The engine operation in modern cars is managed by an electronic controller (ECU), which receives information from a variety of sensors. If troubleshooting occurs, the system activates the warning indicator "Check Engine" on the instrument panel. Many drivers do not know what to do in a situation where suddenly and without explicit reasons, the engine malfunction lights caught fire.
Why engine malfunction free
In the memory of the electronic unit, a service program is set (as an operating system on a home computer), with which the ECU controls the modes of operation of the motor. If the readings of some sensor differ from the regulatory, the controller remembers the malfunction code and includes the Check Engine warning signal.

Most often, if the engine malfunction has caught fire, this means the failure of nodes or control devices of the following car systems:
In the fuel system: incorrect operation of the nozzles, fuel pump malfunction, adsorber, as well as a tank tightness disorder;
In the ignition system: unstable operation of spark plugs, malfunctions of high-voltage wires and ignition distributor;
In the output systems of the exhaust gases: a malfunction of the oxygen sensor, a breakdown of a catalytic neutralizer;
In the engine control system: Malfunctions of the mass flow sensor, the detonation sensor, idle regulator and other devices.
Machines equipped with an on-board computer with a self-diagnostic function have the ability to display the error codes on the screen. For other models, it is possible to determine why the enhine check, you can only with a laptop with special software that connects to the diagnostic connector through a compatible cable.
If the check caught fire when started on a cold engine
If, when switching on the ignition, there is no characteristic sound of fuel pumping, and the engine icon caught fire on the panel, then, most likely, the relay feeds to the gas station is faulty.
The exact installation location of this device depends on the specific model of the machine and can be in the immediate vicinity of the fuel injection control unit or next to the fuse block. The causes of the lack of relay can be like a malfunction of the device itself and the failure of the protective fuse.
A faulty gas-pump relay must be replaced with a new one, and when the fuse is bothering, it is necessary to determine and eliminate the cause of this problem, since possible closures in the wiring can lead to a vehicle fire.
If there are problems with the launch, the cold engine is unstable, the fuel injectors were probably clormed or their electrical wiring was faulty. To resolve the problem you need to wash the injection device, and eliminate damage in electrical control circuits.
The reason that after starting the engine, the check signal is lit, there may be a violation of the normal operation of the device to absorb the vapor of gasoline - adsorber.
This happens if the absorbing element (activated carbon) is disqualled or the electromagnetic control valve fails.
Many car owners remove the adsorber spent due to the high cost of the new part. In this case, it is mandatory to overwrite the firmware of the control unit to avoid the constant appearance of the error in the system.
Often a warning indicator lights up without malfunctioning due to elementary inattention. A poorly tightened in a hurry plugging of the fuel tank of the fuel tank reduces the pressure in the benzbins due to air transmission. This leads to increased gasoline consumption, which the computer evaluates as a malfunction and then the panel turns on the check lamp.
Another reason may be a fault of the air flow sensor. To ensure the optimal composition of the fuel mixture, the control unit controls the consumption of air using the air flow sensor readings (DMRV). With an irregular replacement of the air filter, the DMMV work element is clogged with dust particles, which leads to a distortion of its testimony.
In such a situation, the ECU enters the calculation of the air-consumed by the air by indirect methods and warns the driver about a malfunction through the included "Check". Also at the failure of the DMRV, the engine is poorly started at a negative ambient temperature.
The replacement of the air flow sensor is quite simple, however the cost of the part itself, depending on the brand and the car model, can reach 10 - 15 thousand rubles. Therefore, it is better not to save on the routine maintenance of the machine and timely acquire and set a high-quality air purification filter.
Control of the occurrence of detonations When combustion of gasoline in the cylinders is carried out using a detonation sensor. In the absence of information or low signal level from the sensor, the computer submits an error message to the dashboard.
The constructive sensor consists of a piezoelectric element and a resistor, so it is not subject to repairs and varies assembly.
For the installation and maintenance of the necessary revolutions in different modes of operation of the motor corresponds to the idle regulator (RXX). The controller opens and closes a specially hole in the height of the throttle assembly for dosing air. As a result, the car can start moving immediately after starting the engine without long warming up.
Unstable operation of the motor at idle and the engine of the engine fault signal flags about the RHX breakage and the need to replace it.
Check signal worked on the go, the engine troit and works with interruptions
Normal motor operation is impossible without stable ignition of fuel mixture. If "Check Engine" caught fire on an unstable engine running, it may mean the absence of spark or ignition skipping in cylinders due to the following faults:
pollution or failure of spark plugs;
wrong gap on candle electrodes;
test insulation or impaired contacts of high-voltage wires;
ignition coil breakage.
Repair work consist in cleaning the candles and the installation of the correct gap. If the candles have worked a significant period (over 100 thousand kilometers) or have visible defects, they should be replaced with new ones. In addition, even fresh candles can be out of order due to the use of low-quality gasoline. You also need to check the high-voltage wires for damage, make sure that normal sparking, as well as measure the resistance to the coil outputs.
There are no cases when the check is still on after replacing the ignition system parts. If the installed parts are probably working, then you need to erase the error from the memory of the ECU or wait until it disappears automatically through a certain interval (usually from 150 to 300 kilometers of run).
Periodically turns on the "Check Engine" signal, the motor is badly gaining momentum
If the check lights up when moving, and the engine power decreased significantly, it may be caused by faults in the output system of the exhaust gases.
In the exhaust system, the control unit controls the operating mode of the oxygen sensor (lambda probe) installed on the exhaust manifold, and also estimates the state of the exhaust gas catalyst.
The lambda sensor malfunction can be judged by significantly increased gasoline consumption, hanged by carbon dioxide in the exhaust, as well as to reduce the power of the motor. There are several such sensors on modern machines, so you have to either check them in turn, or use the error scanner.
Also, a serious drop in power is a characteristic feature of the malfunction of the exhaust gas purification catalyst. In such a situation, in addition that the engine check was caught fire, the car begins to react very sluggishly to press the gas pedal. Most often, the catalyst breakdown is caused by a malfunction of the oxygen sensor and an untimely replacement of the candles. In order not to bring the situation to an expensive replacement of the catcollector, it is necessary to comply with the regulatory deadlines for replacing incandescent candles.
Warning "Check engine", the machine does not pull, grows the heating of the engine
This problem is caused by the failure of the cooling system. First of all, the thermostat should be carried out, perhaps it is jammed on a small circle, and the hot antifreeze stopped circulating through the radiator.
Another option is the failure of the cooling fan or its control electrical system. In turbocharged models, when the engine overheating, the turbine is automatically disconnected, which leads to a sharp snack of power and a reduction in traction characteristics.
Ultimately, the jammed thermostat can lead to a boiling of the coolant, which often leads to the cliff of hoses and depressurize the system.
Also, the problem may be in a fault of a temperature sensor or poor contact on its connector, which is why the dispensed signal comes into the computer.
Warning check lamp after car washing
Sooner or later, each car owner has to perform a sink of the power unit. This may be due to the leaking of oil or other operational fluids, sedimentation of dust and dirt on a wet motor or need to be required after repair work.
If you pre-protect the nodes from the moisture ingress casually or overdo it with a high-pressure washing, then after switching on the engine, the engine troit and stalls, and the "Check Engine" signal turns on the dashboard.
These problems are most likely associated with a violation of the electrical system of the car: unreliable contacts of high-voltage wires, ignition coils and other electronic blocks. There are cases when the waterproof plugs from the control sensors connectors shot down the water pressure.
Eliminate the malfunction follows by checking and thoroughly dry all connectors in the boilers. For additional reliability in suspicious places, you can apply a voltage-free lubricant for electrical contacts.

In conclusion, it is worth noting that the triggering of the signal "Check Engine" always means that there is some kind of problem. If the check is on, but the engine is working normally, the driver still needs to determine how soon the reason for the power of the warning indicator and eliminate it.
With the end of the era of carburetor systems of preparation of the fuel mixture, their place was taken by the fuel injection system. The widespread introduction of electronics in the car system was accompanied by the appearance of a large number of different sensors, electromechanical actuators and more complex car wiring. All this economy has specialized electronic modules, such as engine control module (ECU), transmission control module (TCU), onboard electronics control module (BCM), etc.
In this regard, automakers began to equip cars with additional embedded diagnostic systems. By turning on the ignition, the driver of a modern car, in addition to the traditional control indicators, "Battery", "Maslenka", etc., will see another number of indicators related to the control of the maintenance of the main car systems.
What does the Check Engine indicator mean.
On the shield of car devices with electronic fuel injection, there is no indicator in the form of a stylized engine. It is designed to control the health of the engine control systems. In the English version, this indicator is called "Checkengine", which translated "Check the engine". For brevity, further in the text will use the abbreviation designation of this "CE" indicator.
Based on the author's own observations, some drivers perceive the CE indicator light on the panel as something fatal for the engine and are afraid to continue further movement. Let's look at how serious faults are the inclusion of this indicator and whether to continue moving by car with a burning indicator CE.
The main reasons for inclusion of the "Checkengine" indicator.
The electronic ECU engine control unit based on the algorithm laid in it decides when and how much fuel is supplied to the cylinders when it is supplied to the ignition candle voltage to ignite the fuel mixture when to turn on the cooling system fan, etc. Accordingly, the ECUs are built into the diagnostics tools of these engine systems. Briefly consider which data sources are available for the built-in system of car engine diagnostics.
Source 1. First of all, the engine malfunction is to deviate its parameters of work from permissible values. In the car, the main source of such data is different sensors. If any of the sensors shows the deviation of the controlled parameter from the norm (for example, exceeding the permissible temperature of the coolant), then the diagnostic system is interpreting this deviation as a malfunction in the engine, remembers which sensor recorded the deviation from the norm, enters the corresponding error code and includes CE indicator. To the same fault group can be attributed to the faults of the sensors themselves.
Fuel injection systems.
Source 2.The second data source to diagnose the fault is the wiring of the car. The built-in diagnostic system reveals cliffs and closures in electrical circuits of sensors and actuators, enters into memory the corresponding error codes.
Source 3.. Another source of diagnostic data can be the calculated parameters calculated by the engine control unit. An example is the control of the health of the catalytic exhaust gas convex. Two mounted before and after the neutralizer, on the difference of signals, make it possible to conclude about the efficiency of the neutralizer.
Thus, the inclusion of the CE indicator only indicates the driver that the diagnostic system revealed some deviation from the normal operation of the engine, but this indicator itself is in itself a little-informative and does not allow you to accurately find out which of the engine control systems has occurred. For more accurate diagnostics, it is necessary to read the error code from the ECU memory that the diagnostic system has saved. Specialized scanners are used to read error codes. They are connected to the standard car diagnostic shoe, which is practically in every modern car.
You can highlight "Top 10" most frequent troubleshootingleading to the inclusion of the CE indicator:
1) The failure of a sensor of the fuel mixture system (mass flow sensor, etc.).
2) ignition system malfunctions, ignition pass (, high-voltage wires, ignition modules).
3) failure of oxygen sensors of the release system.
4) Reducing efficiency (resource production) catalytic.
5) air seats through leakage pads and hoses on the inlet or release (laying the intake manifold, gasket of the exhaust manifold, air and vacuum hoses).
6) Cliffs and closures in the wiring (for example, a break or closure of sensor wiring, fuel injectors, fuel pump).
7) Malfunction of engine shaft position sensors (, camshaft position sensor).
8) poor-quality, increased engine detonation.
9) Faults in the power supply system, increased or reduced voltage in the onboard network (generator malfunction).
10) Internal malfunctions of the engine control unit (failure of the unit electronics).
How to pay off the "Check Engine" indicator.
If the diagnostic system has discovered several problems at once, several corresponding error codes will be entered into memory. The CE indicator will burn until there are any error codes in the memory of the diagnostic system. After troubleshooting, you can erase these codes using a diagnostic device. Also, in some cases, errors can erase, simply de-energized the car for several minutes by turning off the battery.
Driver's actions when you turn on the "Checkengine" indicator.
Since the reasons for inclusion of the CE indicator may be many, then the decision to continue the movement should be taken, based on the severity of the fault. In the overwhelming majority of cases, the CE indicator does not require immediate stopping. The manufacturer laid into the engine control system quite high "vitality", and even if some sensors fail, the engine will work, albeit not at the most optimal mode.
Thus, if on the way you saw the CE indicator tagged on the instrument panel, do not panic. If the engine still works stably, and the testimony of other indicators and devices does not show deviations from the norm, then it is quite calm you can get to the place of diagnostics and repair. In this situation, the best option will be the presence in the diagnostic device in the machine that will allow you to find out right on site. Which of the engine systems issued an error, what is the severity of this error and then to make a decision, move on or still reinforce and call the tow truck.
What icon of the dashboard scares the owner "Renault" most? Right, check Engine. Let's try to figure out why the on-board computer records the error in the engine and what to do with it.
Indicator Check and his appointment
Engine icon, Check Engine, which drivers are often called a "check", normally lights up only when the motor starts - and goes out after a few seconds, after the electronics checks the readiness of the systems to work. Literally the indicator value is translated as "Check the engine".
If the "check" does not go out or lights up while driving when the engine is running, it reports that in the operation of the motor and its electronic systems a failure occurred.
To find out the cause of the problem, you need to connect the on-board computer "Renault" through a special cable to a computer and diagnose - read engine errors.
Why does the engine check light up?
Burning Light Check Engine Indicates a variety of problems in the engine. Most often, the owners of Renault are faced with such of them as:
- poor fuel quality / flue tank leak
- bason pump broke, the fuel filter clogged
- insufficient Motor Oil Level
- faulty spark plugs
- lambda probe sensor failed
- the mass flow sensor DMRV failed
- exhaust gas catalyst failed
Caught Check Engine - what to do
As soon as the "Renault" owner sees on his dashboard "Check" while the car in motion, he should stay as quickly as possible, and also listen to the operation of the motor.
- If suspicious sounds are not detected, you can start the inspection of the car.
- If, however, how did Check Engine caught fire, you hear the noise, hum, knock and other extraneous sounds under the hood, the engine troit and loses power - stay as soon as possible and call the tow truck. An attempt to continue moving in such a case of a motor breakdown.
In any case, to the appearance of the "Check" indicator, it is worth a very careful. Discover the battery or throw off the terminal to the rogas icon and continue the movement is not an output. It is necessary to understand the essence of the problem, replace the elements and sensors failed, rather than you to write off everything on "electronics failures".
However, experienced owners can perform a number of diagnostics and even their elimination independently.
What you need to check if "Check" caught fire on Renault
- First it is worth checking hermetically closed Lid Gollard. If the "check" caught fire immediately after refueling - it is possible to guilty poor-quality fuel. In this case, you need to completely merge bad gasoline or Dt from the gas tank and refuel to other, high-quality fuel. If the lid is not tightened enough, or cracked, the indicator will turn around too.
- Open the hood and inspect the engine, does oil and damage spots on it? Then get the dipstick and waiting until the engine cools down, check the oil level, as needed - to make it.
- The main reason why the "Check" on gasoline Renault lights up failure of the elements of the Esud system - Candles of ignition, coils, high-voltage wires, sensors - especially DMRV and lambda probe. Therefore, open the hood, thoroughly inspect the candles, clean them from them, and better - replace, and the whole set is entirely. On how to independently check the ignition coils on Renault, we wrote a separate attention worth paying the insulation of the wiring.
- Diagnostics of sensors better entrust professionals. Oxygen sensor (lambda probe) Over time, covered with oil soot, and cleaning here will not help - the sensor must be changed.
- DMRV "Measures" the amount of air that enters the combustion chamber helps the motor "prepare" the right mixture. If he fails, the engine works unstable, troit, the fuel consumption increases, the "check" lights up - everything is lighting up due to the poor or too rich fuel mixture. The broken mass flow sensor is needed to change the new one. And so that DMRV worked correctly, do not forget about replacing the air filter.
- In diesel "Renault" Indincitor Check Engine can report fuel system malfunctions - The failure of the nozzles or their sprayers, breakdown or corrosion of the parts of the pump. Diagnosis and elimination of problems of high-precision diesel fuel equipment Renault should be entrusted to professionals.
- Also, the "check" can burn because of the failed benzonasosa and deposits scored fuel filter. For the prevention of such a problem, never travel with an empty tank, and on diesel reno, change the filter before cold annually.
- Finally, the reason for the problem with the Check Engine indicator is worth searching in Faults of the exhaust gas catalyst. The catalyst cleans the exhaust of the diesel engine, and when the mud itself is clogged, the engine power drops, the "check" lights up. The problem is characteristic of Renault with an impressive mileage. The solution is to replace the catalyst, but due to the high cost of car owners simply cut it out, replacing the flamesector.
About why the ABS icon appears on the Renault dashboard, we wrote
At this time, all types of cars are equipped with self-diagnostic systems, which, using light bulbs, prompt the driver about faults or deviations from the level of coolant level, engine oil, the absence of a battery charging, critical wear of the brake pads and other indicators. The main light bulb on the instrument panel is the Check Engine indicator controlling the operation of the motor control system. At the check "Check the engine" the coverage of the parameters is so wide that the fault location is determined only with the help of a special code that is displayed on the light bulb panel and remains in the device's memory. Find out why he caught fire in your car or burns on the car panel you are going to buy, you can quickly.
CHECK ENGINE indicator caught fire - Causes and ways to solve
A lightning check of the motor does not always mean a malfunction signal in the control systems of a working power unit. When turning the larvae in the ignition lock into the included position, the light bulb signals the function of connecting the connection to the current source.
What denotes the inscription
Check Engine can display the cause of malfunction
Translated from the English name of the Check Engine indicator gives the driver to the prompt - "Check the engine." The performance of the control light on different types of cars is made differently: in the form of a silhouette of the engine with various options for the inscriptions or without them. When the ignition key turns into the working position, all self-diagnosis lights light up. When starting the engine, they should go out. A luminous indicator with a running motor is a signal of a malfunction of that equipment that it controls. On many cars, the Check Engine LED is accompanied by a friend to attract the driver's attention.
What does this signal mean
Initially, the Check Engine indicator was led by an electronic engine control unit. The task of the signal light bulb included control over the operation of the engine mixing system with injection through the injector. The functioning of the fence and air purification, nozzles, fuel pump was tracked. For this, special sensors were used. But over time, the light bulb was connected to the on-board computer and her duties were added. Today, the "Check Engine" indicators control several engine control units: ignition, combustible mixture, crankshaft revolutions, idle regulator and other systems.
Video: What does Check Engine indicator mean
Causes of the combustion of the check on the carburetor engine with an injector
Why caught fire on the diesel
The motor operating on the solarium, as well as any engine, is always subjected to variable loads. They affect the change in the number of crankshaft revolutions. The selection of the desired mode to maintain the constant pressure injection system is assigned to the control unit.
Diagnostics of diesel engine
This electronic controller changes the performance of the fuel pump depending on the load that appears. Due to this, the system constantly supports high pressure, which is necessary for stable nooks. On the diesel engine, the reason for the lighting of the Check Engine light bulb is much more difficult than on the gasoline engine. Therefore, the Council is:
- Check the oil level in the crankcase, if necessary, fall to normal.
- Turn the machine to the reliable car service to diagnose all motor control systems, automatic transmission and other devices. There, the work of the on-board computer will be checked with professional equipment.
When you can continue moving with this indicator, and when not
It is necessary to understand that from the correct actions of the driver at the time of the discharge of the light bulb "Look the engine" depend on the consequences for the further operation of the car. The glow of the self-diagnostic element during the working power unit prompts the car owner that the on-board computer or the motor control unit recorded the malfunction.
CHECK ENGINE LED caught fire. What to do?
Continue movement is allowedIf the indicator is on constantly (does not blink), and noticeable changes occurred in the car. It also instantly reacts to a sharp pressing of the accelerator pedal. No power loss is observed. The oil level in the engine and antimony crankcase in the cooling system is normal. The remaining bulbs of self-diagnosis are not lit. You need to get to the nearest car service, to install and correct the cause of the management system using computer diagnostics.
But if negative changes in the car work began to be observed: the engine power decreased, suspicious knocks, vibration, began to feel the smell of Gary, and the Check Engine light flashes - further movement is prohibited. The engine must be immediately drowning to avoid serious consequences. Suspicion of overheating of the power unit, the pressure drop in the motor lubrication system and other reasons can lead to breakdowns that will require high costs of money, time and strength.
At what faults light bulb lights up
On board a modern car, a microprocessor control system is installed, which is responsible for self-diagnosis of the engine and other aggregates. This probability provides onboard computer. In its permanent memory (ROM) there is a program that manages the actions of the microprocessor. With normal vehicle modes, the computer regularly checks electronic and electrical systems. If deviations from standard values \u200b\u200bappear, an emergency mode is turned on in the controller. With it, instead of the erroneous parameter of the defective block, a suitable value from the laid program is inserted. In this case, the backup will be entered into the controller's memory as a malfunction.
For the driver's information about this situation in the instrument combination, the Check Engine LED indicator will light up. Microprocessor electronic control unit remembers a special malfunction code. You can read this indicator visually depending on the type of ECU. These may be outbreaks of the LED light bulb of different duration caused:
- fault itself;
- closing the given contacts of the diagnostic connector;
- connect analog voltmeter to certain pinch contacts that serve to connect the read devices.
Fault codes of the ECU "January 4" - reading codes
Flashing Check Engine is the so-called slow codes that carry a small amount of information. They consist of two digits denoting a malfunction in a special table. This encoding of codes is an application to operational documents. The first digit is denoted by long flashes (up to 1.5 seconds), the second is short (up to 0.5 seconds). Between them pause. It is a few seconds.
There are "fast codes" that are able to issue a large detailed amount of information for diagnostic equipment.
It must be remembered that all elements of electronic control react poorly to the external effect: voltage jumps, static electricity and other factors. Therefore, any preparatory work must be kept when the ignition key is turned off.
Table fault codes of the controller type "January-4" VAZ 2110, VAZ 2111, VAZ 2112
| The code | Fault |
| 12 | Feebility of the diagnostic chain of the control lamp |
| 14 | High cooling fluid temperature sensor signal |
| 15 | Low cooling fluid temperature sensor signal |
| 16 | Increased on-board voltage |
| 17 | Reduced onboard network voltage |
| 19 | Invalid crankshaft position sensor signal |
| 21 | Throttle Position Sensor Sensor Sensor Voltage |
| 22 | Insufficient throttle position sensor signal signal voltage |
| 24 | There is no signal from the vehicle speed sensor |
| 27 | High signal level co-potentiometer |
| 28 | Low signal level SO-potentiometer |
| 33 | Invalid air flow sensor signal (high frequency of the signal at the output of the sensor) |
| 34 | Invalid air flow sensor signal (low signal frequency at the output of the sensor) |
| 35 | Idle speed |
| 43 | Invalid detonation sensor signal |

| 53 | Error electrically programmable storage device (EPZU) |
| 61 | Communication error with immobilizer |
In motion when acceleration
If the "engine service" indicator lights up: when touching from the place; burning constantly while driving a car; With its acceleration, the reason is in the insufficient level of oil in the crankcase. You need to stop the car, listen to the engine operation. In this case, extraneous noises, tapping, rattling should appear. Move the motor, check the dipstick. If the oils in the system are not enough, and add nothing to do - it is allowed to get to the house gently. In such cases, it is recommended to move the car to the car service, to accurately find out the reason for reducing the oil level and eliminate it.
The check flashes, the engine troit and does not pull, the car is shaking, turns float
Usually this situation occurs when moving when the engine needs to dramatically add speed. When working at idle turns, everything is fine. The suspicion in the first place falls on the failures in the ignition system. In this case, it is not necessary to experiment with a gasoline engine for checking sparks in the coil, for candles and other manipulations. This can only be done using a multimeter. If the behavior of the car is limited only to the engine from the engine not all cylinders - you need to carefully, carefully, slowly go towards the nearest car service. It is better to pay some money to professionals who are able to find and eliminate the cause than because of their ill-conceived actions to fail the on-board computer or other gentle electronics. In this case, the costs will be much more.
Check caught fire after refueling
Bad gasoline - the cause of unstable engine operation
This problem may arise from the tightness of the fuel system. One of the reasons is a poorly swirling gas tank cover or a defect in it. If necessary, the plug should be replaced. Another reason for the combustion of the check is gasoline refueling with a low octane number or poor-quality fuel. In the latter case, change the gas station. If the fuel is so bad that the car is not stable - it needs to be merged. In all other cases, it is possible to do this: dilute with high-quality gasoline fuel, and readings Check Engine reset the removal of the minus terminal from the battery for a few minutes.
If moisture is inserted inside the engine with an injection injector after washing, heavy rain, when forceing the river, water drops can get on the high voltage wires, the ignition coil, wiring connectors. Here the danger is that the fault does not appear immediately, but after a while. The consequences can be dangerous if the car rides on the motorway. The "Check Engine" LED will light up, and the motor may unexpectedly conjure, lose the enemy or even stall. It will help the removal of moisture with dry rag and drying of all components of the power block with warm air (with a hair dryer).
Check Engine LED lights up on different engine modes
Why Troit Engine
Normal operation of the power unit with an injector depends on many reasons. It is necessary to enhance one of the installed sensors controlling fuel supply systems, air purification, mixing, ignition, and other control units, as the engine begins to work nertramically, unclean, abnormally. When there is a suspect for a malfunction, that is, the engine incorrectly responds to certain acts of the driver, you need to pay attention to the following circumstances:
- What is the temperature on the street?
- Does the motor hear?
- In what conditions does the unstable operation of the engine manifest - when starting from the place, overclocking, constant speed?
- What indicators of self-diagnostics light up?
- When the car was the last time in the car service, what repair work was performed?
Prior to the start of diagnosing the engine control systems on their own or in the car service should be monitored and eliminated such faults as:
- tosola leaks, engine oil, fuel;
- cracking or weak tightening of vacuum hose clamps;
- oxidation of battery terminals;
- violation of contacts in wire connectors;
- smoke, smells, unusual sounds;
- check the level of engine oil, coolant and brake fluid.
The uniformity of the engine operation can be monitored using a paper strip that you need to bring to the exhaust pipe. The leaf should deviate back from the jet of gases and remain in this position with small oscillations.
If there is little gasoline in the tank, it can lead to a check of the check on the instrument panel.
The battery must be maintained in a technically good condition. Voltage on terminals should be within 13.5-15 volts.
Check Engine indicator can light up if:
How to pay off LED Check Engine. Reset mistakes
At different brands of cars, the process of self-diagnosis is launched in various ways. In some turn, the ignition key and by pressing a certain number of times on the gas pedal through some intervals. The engine fault light flashes and you need to read the flashes, translate them into error code and find the explanation on the table. Other error code is displayed on the display of the onboard computer, if you run the process of self-diagnostics through a combination of buttons.

Thirdly for this purpose, certain contacts are brought into the diagnostic connectivity.
A great option that will help save a lot of money on a trip to Car service - buy an automotive OVD-2 or other brand. With it, you can regularly check the engine operation to identify errors to understand which sensor requires a replacement, or which adjustment is broken.
Reset errors through the removal of the battery terminal
Reset errors in the onboard computer or the computer can be the most accessible way - to disconnect the terminal from the battery for a short time. The memory of the electronic devices is reset and the indicator should be ground. But it is necessary to do this only after the error has been decrypted, detected and fixed. There are other ways to reset errors: with the help of a scanner, installing special programs on a smartphone, contact contacts in the diagnostic connector.

If it burns right
Check Engine burns right
The reasons for glowing half of its power of the indicator can be a lot. This is a bad mass on the car, the installation of incandescent bulbs is not the power and type, problems with electrical wiring and other reasons. The advice can be given this: run the process of self-diagnosis and see the error code. Independently checking the reliability of contact on the minus terminal of the battery and all connections with mass terminals. Pay attention to the performance of all light bulbs: in headlights, turns, dimensions, brakes.
Check Engine Self-Diagnosis Indicator Plays a very important role in detecting malfunctions in engine operation management systems and other machine units. Its main task is to draw the driver's attention to malfunction in the operation of the motor, the automatic transmission change box. Moreover, this may occur before this malfunction will begin to reflect on changes in the behavior of the power unit and automatic transmission. The engine will tackle, lose power, fuel consumption may increase. The main purpose of this test light bulb is timely malfunction detection to eliminate them on time.
