What to do if a check caught fire in the car. Check Engine (Check Enjin). When you can continue movement

Engine check light Check Engine lights up when the computer of your car detects the problem in force transmission. This may indicate a serious or insignificant complication, but ignoring this will definitely aggravate the problem, which will lead to significant damage and expensive repair. You can avoid all trouble if you know the causes of the signal. However, it sometimes does not turn off, despite the solution to the problem. In this case, you will not hurt to learn how to reset the "check."

Most drivers annoyed if the "check" still does not go out, even if the car malfunction was fixed. In this case, the computer of your car is faulty, and a small intervention is required to solve this problem.

1. Using scanner

Using the diagnostic instrument is the easiest way to reset the engine check indicator. Here are 5 easy operations:

2. Battery Disconnection Method

Disconnecting battery - This is an old way to discharge the engine indicator. Here are three steps to reset the "check" by this method:
Step 1: Disconnecting the cables from the battery. At this stage, you must use a wrench to unscrew the positive and negative cables.

Step 2: Discharge the remaining electricity. The next thing you have to do is press and hold the automotive signal for about 30 seconds. This action will help discharge the car battery.

Step 3: Wait and re-connect the battery. After disconnecting the battery cables and the discharge of the remaining electricity, everything you need to do is wait about 15 minutes, and then connect the battery back. Error codes will be deleted. (Note: This method may not work on some cars). In the event that after this procedure "Check" lights up again, it may mean that the problem is still much more serious.

3. Injection on and off ignition

Similar to the second method, but without disconnecting the battery. You just need to turn on and turn off the ignition of the car three times in a row with the interval per second at each step. After you finish, start the machine and check the indicator dropped or not.

4. Give the engine control indicator to go out

Wait until the "Check" goes out by itself. The easiest method, because you can practically do anything unnecessary. A computer system in most cars will automatically reduce the problems that may activate the error indicator. If this is a minor problem, it will automatically be corrected, and the "check" will go out. However, if the "check" is still burning throughout three days, you need to apply the methods mentioned above to reset it.

If this continues to occur, despite the following reset procedures, you must show your car in the nearest car service and diagnose it by a professional mechanic. Professional diagnostics uses more complex tools and allows you to identify accurate problems.

Remember: You can always contact our car service where your car will gladly provide professional technical assistance. You can also sign up for us on the planned technical inspection! Please read the repair and diagnostics of the car.

Serial equipment of cars with computer systems that allow you to quickly find malfunctions, it began about three decades ago. Connecting such systems to special testers is carried out at the expense of connectors located in them and is carried out only under the terms of the service by specialists. The car owner is noticed about the presence of chack engine light bulb on dashboard.

A similar alert system is used on modern car models - it is installed almost all cars with injector enginesManufactured by the microprocessor. Therefore, the owners of such cars should have an idea of \u200b\u200bwhat to do if the check light is burning and what can be the causes of its inclusion.

Location of Check Engine. What does his trigger mean?

CHECK Engine Indicator location on dashboard

Check Engine light is located on the car instrument panel. The cause of its response is the detection of the electronic control unit in the DVS error in the operation of any system, node or engine unit. The system controls several parameters:

• the number of motor revolutions;
• composition of the fuel mixture;
• functioning of the ignition system;
• work graduation system and fuel injection sensors and many other systems.

The causes of the triggering of the Check Engine system can be much because it follows the work of many vendors of the car. To determine a particular malfunction, not only knowledge of the system is required, but also the availability of special equipment.

Is it possible to operate a car with a tanned check

No worries

Check Engine Light, like other signals on the dashboard, when starting the engine, light up and go out. This triggering is set to verify the performance of all indicators. Car owner It is advisable to pay attention to this test when running the motor to assess the performance of the light bulbs and no error.

When you can continue movement

You can continue the trip by car if the indicator is uninterrupted, but no changes in the management and behavior of the machine are not seen, the engine reacts normally to pressing the gas pedal, the remaining indicators on the dashboard are not lit. Despite the permission of further operation, it is possible to move in such a situation only towards the car service in order to diagnose the system and identifying faults.

When moving is not worth

If the Check Engine indicator flashes, and its triggering is accompanied by failures in the car's work, then you should not move on. Ignoring the system malfunction signal may cause serious consequences that may result in the need for repair work. In such a situation, it is best to call a specialist or a tow truck.

Under what faults the indicator is on

The exact definition of the cause of the CHECK Engine indicator is possible in the service center in the presence of special equipment. However, getting to short term Before the service is not always possible, so any car owner should be able to independently determine the malfunction.

Definition of Check Engine Error Code in Car Service

When a similar signal is triggered, first of all it is worth checking the most banal things - for example, the plugs of the filling neck for motor oil and gas tank. Many cars today are equipped with special sensors that control the purity of fuel and engine oil. The triggering of such sensors and the CHECK ENGINE indicator is caused. It is also worth looking under the hood - in the presence of open terminals, free cables, the indicator can also work.

Checking the rotor space in case of triggering of the check Engine indicator

If there is no reasons for the triggering of Check Engine, it is worth checking the spark plugs: most often the signal appears precisely because they can pass electricity pulses due to the appearance of nagar and the raid of different metals that are part of the fuel. In addition, the engine malfunction can be associated with gaps between the parts or the appearance of the precipitate on the surface of the injectors.

Spark plugs - one of the reasons for the inclusion of the light bulb Check Engine

Wiring isolation wear with high probability can provoke an indicator triggering. Visually defects are not determined, so they are searched for a special device.

Device for checking car wiring integrity

Serious malfunctions in the car

The reason for the inclusion of the Check Engine indicator may be serious breakdown. Most often have to face fuel pump faults caused by low fuel quality. Diagnostic it is very simple - a working engine is listened. The normal functioning of the motor is accompanied by a smooth sound without interruptions and clicks. If the problem lies in the fuel pump, it is removed, it is thoroughly washed, eliminating garbage and contamination.

The cause of the indicator is a faulty fuel pump

Perhaps the indicator may be due to the ignition coil in cases where it incorrectly distributes the electric charge between the ignition candles. When this breakdown is detected, the part is changed to a new one. If there are individual coils in the car, they find the breakdown with the tester.

Check ignition coil with tester

The lambda sensor breakage and air flow sensor can also be caused by the check engine indicator. Such details are not repaired - only replaced. The failure of the catalytic neutralizer also becomes the cause of the indicator. The non-working exhaust system translates many cars into emergency mode, so the neutralizer is changed necessarily.

Air flow sensor, the failure of which can lead to the ignition of the Check Engine lamp

The control unit is extremely rarely breaking, on which the air supply, fuel injection and other processes depends. The breakdown of such a detail leads to huge costs for the driver. The only way out of the situation is the repair of the device by a qualified electrician.

Additional reasons

Fault power aggregate The car in most cases provoke the inclusion of the Check Engine lamp while driving. In such cases, it is necessary to stop the car, not the gentle engine, and check the remaining indicators on the dashboard. The first thing that should be taken into account is the temperature indicator, the inclusion of which and leads to the triggering of the check engine light bulb. The boiling of coolant can lead to irreparable consequences. Modern models of cars on a critical increase in the temperature of the coolant respond to the triggering of a special icon on the dashboard, symbolizing the thermometer. In this case, it is necessary to either completely stop the car, or continue to go, but on low motor revolutions.

Cooling fluid temperature indicator

The Check Engine lamp can light up in case of operation of the oil pressure sensor. With an extremely low level lubricant Often turns on the laminating indicator. In such situations, the oil level is checked - if it is not enough, then the lubrication is attached. If the level of fluid is normal, then the reason lies in a faulty oil pump. You can eliminate such a breakdown in the automotive service.

Motor oil pressure sensor trigger

Flashing light bulb Check Engine in cases when faulty automatic transmission car. Often, the reason lies in the ECU. When the indicator, the indicator immediately turns on the emergency mode, which affects the engine power and its turns. If the indicator lights up when the engine starts for a few seconds, then there is nothing terrible in it - the control unit is diagnosed with all systems.

How to Reset Check Engine Error

The CHECK ENGINE indicator is always associated with faults and problems. You can define a breakdown by the error code issued using a special tester. However, sometimes the indicator continues to burn even after fixing the problem. In such situations, car owners are trying to reset the error by the method computer diagnostics. The procedure is carried out in a service center on a fee. Reset the Check Engine sensor error on your own.

Reset error as follows:

1. Includes ignition without starting the engine.
2. The hood opens and removes with rechargeable battery Plus terminal.
3. 10-60 seconds and the terminal returns to the place.
4. The hood closes.
5. The ignition turns on and the car starts.

This procedure is sufficient to reset the error. It is advisable to resort to this method in cases of erroneous triggering of the check engine indicator - for example, when entering the fuel of impurities. If the fault is still available, the indicator will work several kilometers after resetting the error.

Check Engine Self-Diagnosis System Faults

Car owners are often faced with the malfunctions of the self-diagnosis system. This is usually accompanied by uneven burning of the check engine indicator, has truncated. The main reason for this is the failure of a diode or a problem with the mass. Experts often adhere to the opinion that the problem is in the dashboard, and this is connected with the features of the car.

The check engine indicator is not a reason for panic and does not always report the need for serious repairs. First of all, it is worth determining the reason for the inclusion of the light bulb and try to eliminate the problem yourself. If you cannot eliminate it on your own, it is worth contacting the specialists in the service center - they will fulfill the system diagnostics and eliminate the malfunction.

No one is insured against the fact that even with the most careful operation of the car, one or another failure in the work of one of its systems will occur. To ensure visual control over the main parameters of the motor and related nodes, a visual tracking system is provided. The so-called control indication allows you to once again react to malfunctions in the engine operation, preventing it in the same way from more serious damage.

Anyway, the test lamp, unexpectedly flashed on the instrument panel, only notifies the driver that the control system has discovered a certain failure. The system only signals a breakdown, but does not allow to judge a particular place and the cause of the problem.

For a more detailed study of the problem, you should use a special scanner for comprehensive diagnostics, more famous among motorists as "Lounch".

Among all other visual alert pointers, an indicator that signals the engine breakdown occupies a special place. IN this case It will takes the operational solution that has arisen. Otherwise, there is a high probability that the engine is simply aroused.

What actions should be taken if the control lamp of the "Check Engine" engine caught fire? Let's try to figure it out in more detail.

When the Check Engine indicator lights up - 10 reasons

In the event that an uncomplicated icon with an image of the engine is displayed on the instrument panel, you should not fall into a panic and immediately contact the nearest one hundred. To begin with, it is necessary to identify the nature and cause of the breakdown.

Special attention should be paid to the manner of behavior control indicator. The fact is that with a certain form of a malfunction, it can burn short-term time, in other cases it burns constantly.

We will get acquainted with the list of the most common causes of the present phenomenon.

1. Low fuel level / fuel tank disorder;
2. Low engine oil;
3. Inappropriate ignition candles;
4. Clogging fuel injectors;
5. Failure of the ignition coil and breakfast bar;
6. The spark discharge is broken into the engine cylinders;
7. Damage to the lambda probe;
8. Violation of the catalyst;
9. Interruptions in fuel supply;
10. Non-quality fuel.

From the first of these reasons, they rarely face, however, it should not be excluded. Often, such a situation occurs when fuel in the tank on the outcome. In such circumstances submersible fuel pump Begins what is called "work in good".

The engine is forced to test fuel starvation. To all other, constructive features The gas station does not allow it to work in this mode for a long time. He simply begins to experience excessive loads that negatively affects its service life and fuel supplies in general. It should also be noted that such a state of affairs is negatively reflected in the work of the lambda probe.

In addition, within the framework of the presented cause, it will not be too easy to mention the lid of the fuel tank.

The fact is that her loose fit to the neck of the tank could cause the appearance of the "check". Indispensable condition of uninterrupted work fuel system It is the tightness and maintenance of optimal pressure. The tank cover equipped with the valve mechanism, in this case plays a far from the last role to ensure the above conditions.

Cause # 2 - low Motor Oil.

Before entering the details of the presented reason, it should be said that any self-respecting car enthusiast, should adopt one simple, but very an important rule - Check the oil level, before each trip. This procedure will not take much time and will save from unforeseen situations.

Where does the engine oil go?

This state of affairs can be caused by the most different factors. For example, the integrity of the engine crankcase can be broken. Due to the mechanical damage to the pallet, the oil can simply lean out. There is also the likelihood that there is an elevated wear of the cylinder-piston motor of the motor.

As a result, the engine compression is reduced, and the oil simply flies into the pipe, as evidenced by the characteristic sIZY smoke exhaust.

"Check" can catch fire and because of faulty spark plugs.

Under failure it is understood that their working surfaces can be strongly contaminated or worn. In addition, you should pay attention to the value of the gap between the electrodes. It must comply with the set parameters.

Do not write off from the account and some of our Russian realities regarding the quality of fuel. Low quality of gasoline cleaning as well unreasonable replacement Filters can lead to clogging fuel injectors. Should consider that these elements fuel equipment Very sensitive react to the quality of gasoline.

In addition to the fuel system, there is a system of electrical equipment of the car, which accounts for much most of all malfunctions. The appearance of a hated light may be due to failure ignition coils.

For example, due to its breakdown, a spark is broken into the engine cylinders. Do not forget about high-voltage wires. They have a property lose their insulation properties and simply "short for mass".

The next reason for the situation in question may occur when interfering with the car distribution system GRM.

Its essence is reduced to the fact that the phases of gas distribution are disturbed. Thus, the spark is submitted at the end of the compression tact, as it should be. Such a situation could arise, for example, when incorrect.

Among the causes of the indicator "Check Engine" may be faulty the Lambda probe. During operation, this simple node is susceptible to increased temperature and mechanical loads.

In this regard, in its work there may be different kinds of interruptions:

• breakdown of the heating part
• low signal level,
• crane chain and others.

To obtain the most reliable data on its performance, the scanner and the tester should be armed.

The culprit of the events described may become catalyst car. He, like any other consumility, comes in disrepair over time. This is a greater extent contributes to the low quality of the fuel used.

Due to the presence of third-party impurities and low level Cleaning fuel, catalyst cells are clogged faster, which adversely affects its throughput. Thus, the engine does not develop turnover, it disappears its thrust and richness.

In addition, the improper fuel quality displays key fuel equipment nodes. The fuel supply is worse in the engine cylinders of the car. This situation cannot remain unnoticed for sensors.

The electronic control unit in turn, analyzing the incoming data from these sensors, signals the driver about the presence of problems with the help of the "Check Engine" control indicator known to us.

Is it possible to go with a burning bulb check

The presented situation may cause the surprise of any car enthusiast. It's one thing when it happened in the city feature, where there is an opportunity to use the services of a tow truck or contact the staff of the service station.

But what to do in the current circumstances, away from the city, on the deserted track? Let us try to find out when it is allowed to continue moving at a burning bulb "Check".

Below is a sequence of actions to be followed in a particular case:

• First, pay attention to whether any additional indicator is lit. Auxiliary control lamp, pointing to a failure in a specific system, will allow the audit of a particular assembly of the car.

For example, if the pressure lamp is on, it can be assumed that in the lubrication system is not enough oil. The temperature indicator can signal a low level. In this case, to solve the problem, refill filling fluids.

This situation forces the driver to significantly change the familiar driving manner. You need to move evenly, adhering to low speed. Do not allow a sharp increase in revolutions and reduce gas. When an oil pressure indicator appears, there is a possibility that the crankshaft liner has occurred.

In this case, a characteristic metal knock may appear. Further movement in this case may result in expensive engine repair. However, in emergency caseIf you do not have a choice, except to continue the independent movement, the gear shift as it is possible.

• With such a fault, it is recommended to move what is called in the tension: evenly, in the range of speeds somewhat smaller than it requires this transmission. The engine must work with a small load.
• Some time after the movement, you should stop. At this time, it will not be superfluous to check the oil level and coolant. Looking into the open space, carefully inspect the engine and its "jamming" for the presence of leaks and oil spots.

Of course, further movement on the car with the engine malfunction included is an unjustified risk. To resort to this follows only in the most extreme case.

Anyway, even strictly follow these recommendations will not give a complete guarantee that you will safely reach the nearest one hundred.

How to pay off the check indicator

There is at least 2 ways with which you can turn off, the so-called "check".

The first method is quite simple and does not require any auxiliary means. To make it in life enough to throw the terminal, after which it again put it in place.

The algorithm of this reception is as follows:

• werewind cars to operating temperature;
• removing "+" terminals of the AKB;
• after 10 minutes. Return the terminal to the right place;
• turn on the ignition and wait 30-60 seconds;
• turn off the ignition.

This procedure will lead to the fact that the data in the control unit will be updated, and all existing error codes will be stranded. Nevertheless, this method does not always lead to the desired result.

In this case, they resort to the use of a special device - scanner or "LOUNCH". This diagnostic device is connected to the installed diagnostic connector. It is usually located under the steering column or near the pedal node.

This scanner allows you to identify violations in the operation of systems and nodes of the car, providing the driver a complete list of errors. If you need, you can reset the error.

Video: How to count and decrypt engine errors

We bring to your attention a video material, thanks to which the driver will be able to familiarize themselves with the methods of counting and decrypt engine errors.

Table: The most common error codes

We provide your attention a review table of the most common error codes.

Modern cars have diagnostic systems at which light bulbs occurs to indicate the driver to an existing specific problem. The main pointer on the panel is the indicator called Checkengine, which is responsible for controlling the operation of the engine control system. This feature has a list of properties so great that the breakdown area is determined solely by means of a special code that appears on the panel. You can find out why the engine check is caught fire, you can very simply, what will be discussed.

Description of the system

The tanning icon is far from all cases serves as a marker breakdown system control system. When the larva turns into the ignition lock, this sign will testify to the connection.

If they deepen into translation, "Checkengine" denotes "Check the engine". Control LED on different models Auto done in a different way. It can be a silhouette of a motor with different inscriptions. When the ignition turn is performed, all diagnostic indicators begin to light up. At the time of launching the engine, they must be ground.

A lightning mark with a running engine serves as a signal of a breakdown of equipment that is controlled.On many TS, this LED is also expressed by the accompanying sound to draw the driver's attention.

Initially, the system controlled the electronic control unit. The responsibilities of this bulb included the management of the system through the injector. Special sensors were used. However, it's time, and the device was connected to the computer, and the duties appeared more. Modern indicators adjust multiple control units.

How to remove the icon

On different models, the auto diagnostics functions differently. Some of them when rotating the key and pressing a separate number of times on the pedal, the indicator lights up. After that, you should consider the number of fires, search in the interpretation table. The remaining stamps appears cipher on the screen when you start the diagnostics through a combination of buttons.

In other brands, contacts begin to bridge. An excellent solution is the acquisition of a special scanner, which allows you to control the operation of the motor and understand that it was failed.

If you are interested in the question of how to remove the engine check, then it is possible to make the most affordable way. In a short period of time, disconnect from the battery. Then the device will be reset, and the lights should go out. But this is done only after an error is correctly defined. There are many other reset methods, for example, the application of the scanner, the installation of special programs, the closure of the contacts.

We establish the causes of sunbathing on the carburetor engine

The main reasons why the engine check is burning, the following factors may be:

1. Poor quality gasoline. It is recommended to cast a liquid from the tank and refuel the quality product.
2. If there is no spark on the candle, it makes sense to check the health of all the mixture fire devices. If necessary, make a replacement of the candle.
3. In the absence of spark on the ignition, you should check the device for goodness.
4. It makes sense to monitor the lambd probe for goodness. The device, failed, should be replaced.
5. It makes sense to examine the device not only because of the tanned icon, but also with bad car indicators. The catalyst breakdown requires substitution, riding without it is strictly prohibited, it can lead to the strongest breakdowns in the design and regular lighting light bulb.
6. When the nozzles were clogged, their cleaning should be performed.
7. If the fuel pump does not produce the necessary pressure, it is recommended to check the fuel filter.
8. If the stress wires are penetrated, the situation adversely affects the functionality of the motor. You need to check the functionality of the caps, contacts and isolation.

Causes of sunbathing on diesel

The device operating on the solarium is subjected to serious loads. All this has an impact on the change of the number of revolutions. To find the required mode, you need to use the control unit.

The electronic device changes performance taking into account the load. Due to this, the device regularly maintains the pressure that is required for the adjustable operation of the nozzles. Why the engine check flashes in this case is quite difficult to say. Recommendations will be as follows:

1. If necessary, framed oil.
2. Take the car to a good car service to check all control systems. You will check the functioning of the system using professional equipment.

If you glow in Polkanal

When the check is on half, everything can be several reasons. Among them are a bad mass on the car, the establishment of incandescent lamps, malfunction with wiring and so on. Enable the diagnostic process and check the code.

See how absolutely all light bulbs work. The diagnostic indicator is of great importance in identifying malfunctions in control systems and other devices. The main goal is to define breakage. This can happen even until the problems begin to manifest themselves on changes in the behavior of the power instrument. At the same time blinking the check and the engine troit, gasoline consumption increases. The most basic task is to determine the problems in time for their liquidation.

Can I go when sunbathing indicator

The reasons why engine malfunction is burning, a lot. If the motor malfunction is completely dangerous.The situation is significantly complicated by the fact that it is quite problematic to identify the problems of the modern aggregate.

It is necessary to refer to the masters that the scanner will determine the problem.

When, after the secondary launch of the machine, the light bulb was not dead, you can only go to the car service. Experts will perform a comprehensive diagnosis of the motor and all components.

Application vehicle with a fitting indicator contributes big flow gasoline, instability of the operation of the engine, decrease traction properties. The driver in this situation has every chance to lose guarantees for the repair of its vehicle.

In what situations the indicator lights up

In modern TS, the control system is functioning responsible for the diagnosis of the motor and other fixtures. This feature provides a computer. It is equipped with a special program controlling the functionality of the processor. When the car works in normal mode, the computer systematically checks the function of the system. As soon as violations arise, the accident is started. Instead of problems with the block parameters, the desired program value is set. The backup indicator will be entered into the device's memory.

To inform the chauffeur about this situation in combination of equipment, the indicator lights up. You can visually see this value, taking into account the species of the ECU. The ignition of the LED may be provoked:

1. Breakdown.
2. Closing.
3. Connect a voltmeter to contacts.

Flashs are certain codes with minimal information.. They include several indicators talking about the problem in a special table. All these codes serve as an addition to operational papers.

There are also instant codes that mean a huge information for diagnosing the system.

It is worth noting the fact that all components react poorly to exposure from the outside. Any preparatory work Must be performed when the ignition is enabled.

Movement and acceleration

If the engine malfunction was caught fire at the time of departure, systematically flashes at the time of movement of the machine, as a result of acceleration, it is recommended to replace the oil. Stay and check the operation of the engine. You must hear unnecessary sounds, tapping. If the oils are very little and nothing to add to him, you can carefully reach the house, take the car to the service in order to determine the oil reduction factor with accuracy.

Troit engine

Why a check and troit engine? As a rule, such a phenomenon makes itself felt after the motor need to gain sharply turns. When the machine functions at idle, everything is normal. It makes sense to suspect a ignition problem. No need to conduct experiments in this situation. This can be done by multimeter.

When the behavior of the vehicle is limited by the operation of the motor not all cylinders, should be slowly sent to the nearest car service. It is better to give a certain amount to real masters than its wrong actions to harm the technique. Surround, as you know, pays twice.

Problem after gas station

If tightness fails to comply with this phenomenon.When there is flaws in the tank cover or it is badly closed, a light bulb can light up. Here it is recommended to replace the cork. Another weighty reason serves a fuel in fuel of poor quality. It is recommended to fill fuel and change the gas station.

When raindrops fall inside the system and so on, the problems will not know about themselves not immediately, but only after time. In this case, it is necessary to remove moisture with a dry vein and a powerful drying of all parts.

Light bulb is glowing in different modes

The normal functioning of the system depends on the whole set of reasons. It is worth out of order at least one element, so immediately the motor will start functioning badly. If there are suspected problems, the motor will not respond to certain actions. What should be done:

1. Determine the temperature on the street.
2. Find out how much the engine is heated.
3. Under what circumstances the instability of the engine work is expressed.
4. What light bulbs are ignited.
5. What repair work was last carried out.

The usefulness of the motor functioning can be checked with a paper strip that is presented to the pipe. She must deviate back and stay in this position with minor fluctuations. If there is little fuel, it can be reflected by the air of the check.

The reasons for the ignition of the indicator placed on the car panel, there is a huge set. Each of these malfunctions implies its actions and a certain strategy for solving the issue. Some problems can be solved and yourself.

The unquestioning follows of all the rules of professionals will help extend the period of operation of your unit and will help to obtain real satisfaction in the process of movement.

Modern models of machines have a special indicator on their instrument panel or that translated into Russian means "Check the engine". She signals that in power installation Auto or other nodes and units have a problem, which can negatively affect the quality and safety of movement. Consider in more detail what Check Engine means and what actions need to be taken when such a signal appears.

Tableted Check Engine icon Indicates the presence of a problem

Purpose of the diagnostic system

When Check Engine light is on, it suggests that the electronic motor control unit has detected an error in the operation of any of the engine nodes. The following parameters are subject to control using this system:

• motor turnover,
• operation of gasoline injection sensors and exhaust system,
• functioning of ignition and much more.

Considering the number of controlled nodes, the causes of the check engine indicator can be quite a lot. And to identify them, some knowledge and skills are needed, and in some cases special equipment.

Actions when acknowledge is detected

Consider what to do if CHECK Engine caught fire? Immediately, it should be noted that the flashing of this light bulb does not always mean breakdown. If she flashed at the start of the motor and instantly extinct - it is not necessary to worry. But if she worked during the movement of the car and flashes a long time - attention should be paid attention and take measures to detect a problem.

The reasons why this happens can be divided into 2 groups: easily corrected and more critical for the machine operation. In the latter case, you must immediately go to the service for diagnosing and correcting breakage. In many other cases, you can cope with the trouble yourself.

Causes of triggering indicator

In most cases, the reason why Check Engine light was caught fire, are:

1. Unlocked gas tank cover. It can be poorly twisted or lost while driving. This affects the pressure inside the fuel system, it deviates from the norm, which and reports the driver indicator. To resolve the problem, you need to close the tank more closely or buy a new lid.
2. Moisture hit. The indicator can light up during the rain or after the engine washing, when water falls on the spark plug wires, causing short circuits, perceived by the control system as a malfunction. In such situations, it is necessary to be more attentive and after washing to ask the employee to dry the compounds of high-voltage wires by air flow.
3. Poor quality gasoline. Even a small amount of impurities in gasoline affects the operation of the spark plug, as a result they give failures. Review this helps the presence of nagar on them. If the cause of the indicator is triggered in this, it is recommended to drain low-quality fuel and replace it with another.
4. Insufficient oil level. When the CheckenGine lamp flashes during the movement, you need to stop, open the hood and listen to the noise and sounds published by the engine. If some suspicious and warming sounds are not heard, and the inspection of the motor did not reveal any visual defects and herds, it is necessary.

However, sometimes this signal may be a consequence and more serious problems:

1. Ignition Candles with faults. Inspection can reveal big Clearance between the electrodes or crack in the insulator. In the first case, the clearance value is not more than 1.3 mm, in the second - replace the candles.
2. Fault of the ignition coil. It is necessary to figure out whether the spark is issued, as well as measure the amount of resistance on the conclusions of the coil. If there is no sparks or a multimeter shows a large discrepancy from the nominal value, the part must be replaced.
3. Breakdown - lambda probe. The inoperability of this element often entails the triggering of the check engine light bulb. If the test confirmed this, the best output from this situation will be replaced by a damaged part.
4. Catalyst problems. The catalyst is verified for the presence of defects and in case of detection of problems changing to a new one.
5. Problems with nozzles. If there is a suspicion that they work incorrectly, you need to check if they were not clogged, and clean. If this event did not help, you need to change the nozzles to new ones.
6. Incorrect operation of a fuel pump or fuel filter. Change the malfunction by replacing the defective or served your items.
7. Low pressure in the ramp. It is necessary to check that this indicator is at least three atmospheres. Otherwise, you should clean the filter or change the fuel pump.
8. Defect of high voltage wires. To check them, you need to perform the following steps. In a saucepan of aluminum or stainless steel, pour the salt solution based on the proportion of 1 liter of water 1 tablespoon of salt. Lower there the wire so that the tips are above the water. Attach to one tip of the megommeter, other strengthen on the saucepan. If the indicator is less than 500 com, then the resistance is insufficient and should be replaced with the wires.

Diagnosing a problem with a special computer

Many drivers face a situation when Check Engine is burning, but there is no car that would indicate a specific problem. Then it is necessary to use a diagnostic scanner, which, when connected to the onboard car, gets access to electronic block Engine control and gives a damage code.

Computer program Check Engine with a special adapter allows the driver to use the usual PDA, mobile phone, Laptop or CAR PC as a diagnostic device that can determine the cause of the indicator's response.

Using the mentioned software and hardware complex you can:

• read, decrypt and delete fault codes according to the manufacturer's manufacturer;
• perform control of the parameters of the operation of the motor, such as turnover, temperature, state of sensors, and so on;
• control gasoline consumption;
• take into account the distance, time, middle speed And other parameters of the movement of the machine.

How to remove the error from the dashboard

After troubleshooting the indicator itself on the dashboard does not go out. Therefore, let's look at how to remove Check Engine error after completed repair.

It can be removed from on-board computer manually, but only after you checked the presence of the above causes of the indicator's operation and eliminated the problems. If I could not do anything - it is better to contact the car service to specialists, so as not to harm the car even more.

If you carefully follow the check engine, on time and correctly react to its signals, identify possible reasons His triggering and quickly eliminate them, then your car will serve you for a long time without the need for overhaul.
