Adaptation of electronic throttle valves Nissan. How to adapt the throttle damper in the car when the electronic pedal is needed

How does the electronic gas pedal work, as its advantages and disadvantages manifest, what faults are most often found, and how to deal with them? All these questions are very relevant, because today many car manufacturers replaced the traditional cable drive to a more modern electronic pedal.

Gas electronic pedal - how does it work?

Modern technologies are aimed at facilitating our lives as much as possible. On the one hand, this is a huge plus, but on the other - they simply deprive us of the opportunity to make any decision, or rather, adjust it, and in such a way that you can not always achieve the desired result. It is clearly visible and when working so popular in the modern automotive industry of the electronic pedal. Although for those who feel intensely behind the wheel, and even more so do not delve into the technical nuances of the car, this innovation is only in plus.

The principle of operation of the electronic pedal of the gas is as follows: After pressing the driver driver, data about pressure angles immediately fall into the control unit by means of special sensors. Next goes ECU, which is calculated by the desired opening angle, and the drive, based on the data obtained, opens it to this angle. At the same time, if suddenly it will be necessary to change the value of this angle (for more economically or security mode), then the control unit does it, without receiving the appropriate command. It turns out that the driver can not regulate this process for all 100%.

When is the replacement of the electronic gas pedal?

Due to the fact that this is an electronic drive, then the main faults in it are associated with electronics. Two sensors are embedded in the pedal bracket, which transmit commands to the control unit. If one of these sensors fails, the light bulb will turn on the panel, which is responsible for the service of the engine control system. In this case, the ECU goes into the standby mode (the turns grow much slower). If two sensors came out of the order, the emergency mode will turn on, and the engine will work as on. Since the repair sensors are not subject to, it is necessary to replace the electronic pedal of gas.

It may also be damaged, and then the throttle work is disturbed. If the electrical engine was worn out, then an error pointing to an accident is also issued on the monitor. These damage can be eliminated, but if the electronic pedal accelerator has been released, which is responsible for the dynamics of the car, then this part should be replaced immediately. How to do it, we will look at just below.

Repair of the electronic pedal of gas - correct the breakdowns themselves

Mostly, with any problems, the replacement of the entire node as a whole is required. But before you begin to such decisive action, it would not hurt to find out the cause of the breakdown. For this, of course, it is worth familiar with the information as to check the electronic gas pedal. To do this, you must disconnect the block and sensors, and then by unscrewing the fastening nuts, dismantle the pedal.

Directly for verification will require a multimeter: connecting it to different conclusions, follow the change in electrical resistance. It should decrease smoothly, if the jumps are observed, then the item is faulty.

In some cases, the repair of electronic pedal of gas is possible, for example, when damaged wiring. So, finding a defect (insulation is broken, the wires themselves are damaged, etc.), you need to act according to the following scheme. After freeing the axis of the fastening of the gear, remove the harness. To do this, you need to disappear wires, freeing the bracket and pull out the cable. Then we produce wire replacement, and, breaking the connector under the pedal, we sing them. Now you can collect the damper and calmly ride.

If the car reacts to pressing the accelerator, so to speak, "with a delay", then a spur is needed (electronic corrector) gas pedals. This device reduces the interval between pressing and opening the flaps to a minimum. This is a separate module that connects to the sensors and transforms the signals supplied to them through the microprocessor, and then supplies them to the controller.

So we see that the electronic gas pedal, the tuning of which is possible in any specialized center, on the one hand, is a clear result of progress, and on the other - somewhat limits our desires. True, if you do not feel about the category of those people who need to "ride with the breeze", but prefer to drive carefully with minimal fuel costs, then this option will be for you.

Modern technologies have now touched almost all parts of the car. If the gas pedal drive was exclusively mechanical, then now, it comes to electronic. In this article, you will learn what kind of electronic gas pedal, the principle of its action, how to adjust its adjustment and repair.

Device and principle of operation

To understand how the electronic gas pedal works, you need to know the general principle of operation of the accelerator. The fact is that their functions are extremely similar, but the simplest mechanism is the mechanical drive.

The pedal of the accelerator, or as used to call it - "gas", is a means of controlling the position of the throttle valve.

The throttle, in turn, is responsible for the amount of air supplied in the intake manifold engine. The more oxygen enters the combustion chamber, the higher the turnover of the crankshaft. The pedal is a lever that affects the damper drive. The drive can be cable or lever. All this, one way or another, facilitates the effort attached to the gas pedal.

The principle of the electronic pedal is a bit complicated, but many times makes it easier to control the engine turnover. Such a pedal is applied only on injection vehicles, as it is completely based on the operation of electronic devices. The accelerator includes: a pedal module, a signal conversion module and a throttle position control unit.

When you click on the pedal, the module transmits information about the angle of the lever deviation to the signal conversion module. The transistor system transmits a reinforced signal to the throttle control unit. After agreeing the resulting signal with an electronic control unit, the throttle module determines the angle of its opening. Thus, an electronic way to open the throttle valve is provided.

It is worth noting that the work of the valve module cannot begin until the permission from the ECU is obtained. The fact is that this system should know exactly how much air and fuel is needed by the engine in this mode of operation. Therefore, the position of the damper may vary regardless of how much the accelerator pedal is squeezed.

How to adjust the electronic pedal

Like any mechanism, the electronic gas pedal sometimes also needs adjustments. This event is necessary to maintain the normal operation of the accelerator in the event that the settings were shot down.

Sometimes it happens that when you click on the gas pedal, the car ceases to respond to changing the position of the throttle. This is due to the fact that there was no change in the situation simply. All electronic pedals have a certain free course, in the process of which the voltage supplied to the transistor chain changes. If the voltage changes, the reaction to the position of the pedal also changes, therefore, the car may inadequately behave at. Sometimes this problem can be found in the appropriate indicator on the dashboard or using electronic diagnostics, conducted by the car's side computer.

Adjustment order:

• First of all, it is necessary to remove the pedal from the landing place. This means that when removing the pedal, it is dismantled with it and an angle measurement module. The plug connector must be left in its place, since the power to the pedal will be needed during the adjustment process.
• As soon as the pedal is released, unscrew the screw located on its lid. Thus, it is necessary to free the lid relative to the pedal, giving it the opportunity to rotate freely. Next, you will need reference literature attached to the pedal.
• Connect between the voltmeter connectors and set the corresponding measurement range on it. Turn on the ignition. In the directory to the pedal there are voltage standards that will be different for diesel and injection engine. Turning the pedal cover, you can change the supplied voltage. Configure this parameter according to the documentation and tighten the attachment screw.
• Install the pedal on the seat and try. If the behavior of the car has changed for the better, it means that the electronic pedal adjustment is carried out correctly.

Attention!The reference literature may indicate the voltage range. Two numbers determine the magnitude of tensions with a non-pressed pedal and completely squeezed. Therefore, the setting is performed on the first voltage when the gas pedal is not squeezed.

In addition, the magnitude of the voltage may vary depending on the environment. That is, during seasonal car maintenance, it is strongly recommended to be adjusted and gas pedals, since such a value may vary, inversely proportionally changing resistance.

The repair of an accelerator with an electronic drive is made on the basis of detected faults. Like all parts, such a system also has a certain wear, the appearance of which is impossible to prevent. In this regard, it is important to know how troubleshooting is performed when the electron pedal is cracked.

Usually, the pedal repair is started when the following faults are discussed: a short-term refusal to change the position of the pedal or the full failure of the pedal is observed, regardless of the press angle. Basically, these faults are associated with the lack of nutrition on the executive bodies, or the absence of a signal from the pedal module.

First of all, it is necessary to inspect the electrical wiring for scattering, damage to isolation (short circuits) and the absence of contact in plug connections. Very often, the fault of the wires disappears in the responsible bodies and the pedal simply refuses to work. In case of detection of defective electrical current conductors, they must be replaced immediately.

Another fault is linked to breakdown. This error is displayed as a special code "022", or, as it is also called - the "throttle crash". In this case, the motor must be checked. To do this, it is dismantled and connected to the source of electrical energy directly according to the rated current and voltage. If the motor rotates, the fault must be sought elsewhere, although such cases are rare. If the motor does not rotate, then it is subject to replacement.

All other faults are eliminated by the replacement of the module entirely, since their repair is quite complicated and inexpedient. In fact, it is easier and cheaper to change the part of the whole, rather than producing it.

That's all you need to know the driver about the electronic pedal of throttle control. We hope that this article helped you deal with this complex and confusing mechanism.

The value of the throttle adaptation procedure is difficult to underestimate, while not every motorist knows how to perform this operation on its own.

1

During the operation of the throttle node of any modern vehicle on the surface of the choke, many pollution in the form of dust, soot, oils are gradually accumulated. They form a layer of dirt, which makes the air gap between the damper and the car duct less than the set norm. This gap is important for the normal functioning of the "heart" of the car, since, thanks to it, the idling turnover is maintained at the required level.

When it decreases, the electronic control unit of the vehicle (computer of the car) opens the flap by the introduction of coefficients that take into account changes in its cross section. Until a certain moment, the ECU manages to support the air gap at a constant level, but sooner or later still have to be cleaned of dirt. After flushing this node, the engine turnover will necessarily increase due to the fact that the cross section of the throttle exempt from the polluting layer will become more.

The return procedure to the initial (manufacturer given) the position of the damper is called it to be learning or adaptation.

The need for such an operation suggesting the performance of high idle speeds, occurs not only after washing the throttle assembly, but in other cases, in particular, in the following:

• after the full discharge of the vehicle battery;
• after replacing or removing the accelerator pedal;
• after replacing or reconnecting the electronic control unit, the TC.

Undoubted signs that are invited to immediately train the damper, are the following phenomena:

• whistling sweatshirt;
• inadequate motor behavior at idle;
• lack of power at idle or failures.

3 Conditions for the implementation of the idle adaptation process

Before starting training, a number of mandatory conditions should be followed:

• riding a car for 10 minutes;
• provide ankb voltage at idle at least 12.9 V;
• warm up the gearbox;
• tC wheels should stand straight, the steering wheel is in the middle position;
• engine temperature - 70-95 ° C;
• all devices that have the load on the power supply of the machine (glass heating, headlights and so on) should be turned off;
• automatic gearbox selector put on N or R.

Adaptation of these devices is desirable to fulfill before you teach idle. If the sensor cable that sends an accelerator pedal position is disconnected, the following steps:

1. Completely release the pedal.
2. Rotate in "ON" the ignition key, wait at least two seconds;
3. Turn off the ignition, withstand 10 seconds;
4. Repeat the procedure according to claim 2, and after and according to claim 3.

The procedure described (agree, completely simple) will teach the valve to the correct discovery. But to adapt the valve, the position "closed" should perform such operations:

1. Let go (completely) the accelerator pedal.
2. Put the key to the "ON" position.
3. Ignition We switch to "OFF" and wait for 10 seconds.
4. We ensure that the valve lever takes place for 10 seconds (about the fact that the movement is available is indicative of the characteristic sound).

5

Now you can proceed directly to idle training, "armed" by the stopwatch and some patience. The procedure is performed as:

• The engine starts and warms up to the standard operating temperature.
• Ignition turns off, no action is made within 10 seconds.
• The ignition turns on (the accelerator pedal is in the subject), we are waiting for 3 seconds.
• The following actions are performed five times: the accelerator pedal is fully pressed and completely released.
• After 7 seconds, the pedal is pressed again (completely) and is maintained in such a state for 20 seconds.
• Fully (and at the same time without delay) the pedal is released at the moment when the fault indicator flashes on the panel (it should burn with even light).
• Then immediately, without touching the accelerator pedal, you need to run the motor so that it functional at idle.
• We are waiting for about 20 seconds.

After all the voiced actions, I accelerate the engine (2-3 times) and make sure according to the standards of the angle of the ignition and idle speed. On this procedure, the valve adaptation can be considered completed.

Sometimes in the operation of the engine failure, and its turnover is knocked out of the specified values. As a result, idling turnover becomes unstable, failures in power occur.

It seems that the motor, from minute to minute, will stall. It is explained by the detail wear, and as a result, an increase in the gap between the throttle body and the flap. The disturbed clearance passes the air more than the norm, and this is the reason for the change in the composition of the fuel mixture.

The result is the engine malfunction. When wearing the damper (Pyatak), it is necessary to replace it. By virtue of the ease of design, it is not difficult to order it with a familiar Turner or find on the Internet from some "Kulibin". The price of the purchase detail will be much higher.

Since new car models are already going with electronic throttle control (electronic pedal), then malfunction of the car can also lead to the work error.

A sharp voltage jump in the car network, the removal / replacement of the electronic control unit, the accelerator pedals - all this can cause a violation of this part of your car. Then it becomes necessary to return all parameters to normal.

When you should not perform adaptation of DZ?

It is worth noting that to conduct the procedures above, using software software and special diagnostic equipment, appropriate in case of damper settings fail. It does not matter whether the electronic parameters are violated or mechanical equipment settings have been shot.

If the operation of the throttle is violated due to wear, then it is more expedient to think about repairing or replacing the part. If suddenly, after the actions described above, the adaptation does not happen, it is worth checking the motor responsible for opening / closing the damper. Perhaps the power is not enough for the proper operation of the node.

On the example of the adaptation of the throttle of the above-mentioned auto, it can be concluded that some common processes are characteristic of absolutely all cars.

So, for example, clean the damper body inside and outside before starting adaptation, it is necessary for any car brand.

In that only the difference that in some cars, the valve adjustment is carried out using a cable, and in others with electronics. This difference will appear in the selection of adaptation parameters.

In order for the car regularly worked and did not appear for a hundred as long as possible, with the exception of maintenance cases, it is necessary to relate to him carefully. One of the important assemblies of the iron horse is the throttle (DZ). This mechanism plays an important role in the operation of a diesel or gasoline engine. Moreover, it does not matter, the carburetor is a power plant or injector. DZ can be both mechanically and electronically driven. In the latter case, sometimes it becomes necessary to adapt the throttle valve. How to do it? Let's try to figure out, at the same time consider the views of this node. Also find out whether it is necessary to do this, and what can be otherwise.

Purpose of throttle valve

Without such an aggregate, like a throttle, not a single car in the world. The mechanism is a transverse channel regulator that changes the amount of leaking fluid or gas. That is, in essence, the flap is an air valve. When it is closed, the pressure in the inlet system is equal to vacuum, and with its open state, it is compared with an outdoor atmospheric.

Pressing the accelerator pedal is regulated by the degree of opening of the flaps. Accordingly, it depends on how much air will be accepted into the engine cylinders. Almost every modern car is equipped with an injection engine, where all important duties takes

As some motorists know, the optimal ratio of gasoline and air is the proportion of 1: 14.7. Determining the position of the throttle and the amount of air with the help of sensors, the computer regulates the operation of the nozzles and the fuel pump. This knowledge is useful to solve the question of how to adapt the throttle.

In other words, the computer gives the team how much fuel must be in the engine to observe the optimal proportions.

Mechanical throttle valve

Currently, the mechanical drive valve can only meet in the budget configuration of the car. In such a mechanism, the flap is connected to the accelerator pedal by means of a metal cable, fixed on the shaft and placed in the housing, which also places sensors:

• the positions of the throttle (DPDZ).

All this looks like a separate unit. There are still various pipes, the coolant is supplied and the cooling fluid is applied, and the crankcase is ventilated through others and the fuel pairs are trampled.

Thanks to the PXX, when the valve closed, the required number of crankshaft revolutions is supported. The regulator itself consists of a stepper motor and a special valve. Together they control the amount of air, and independently, in which position is the throttle. Typically, problems regarding how to adapt the throttle, in the case of a mechanical drive does not exist.

Electromagnetic throttle valve

The electronic analogue, in contrast to the mechanical unit, allows you to achieve the optimal torque value at any mode of engine operation. The level of fuel consumed is reduced, and riding on such a car is comfortable and safe. The main distinguishing features (and in this case and advantages) are the following:

• idling is regulated by moving the throttle;
• there is no mechanical connection between the pedal and the damper.

Due to the fact that there is no mechanical connection, the torque can be controlled by electronics instead of gas pedal. The damper module itself consists of the following elements:

• hull;
• the damper itself;
• electric drive;
• reciprocal mechanism;
• caller position sensors.

Installation in a module is not one, and two valve position sensors will increase reliability. To do this, magnetorevatory devices or potentiometers having sliding contacts can be used. Just because of the breakdown of these elements, it is necessary to decide how to adapt the throttle on many cars.

If the electric drive occurs, due to the return spring mechanism, the flap is driven into an emergency position. At the same time, the module itself is to be replaced, which is made only in the collection.

Close of throttle valve and cleaning periodicity

From time to time, the throttle valve is inevitably clogged, which is manifested by different signs. In this regard, there is a reasonable question: with what periodicity should it be cleaned? It is not possible to unambiguously answer it, since there is no recommendations about this. Some car owners visit Automaster if the engine is suspected.

Someone believes that the flap needs to be cleaned after every 40000-50000 km of mileage. Others adhere to other opinions and clean the damper more often, after 300,000-40000 km of mileage.

Usually, black nagar on the flap testifies to low fuel quality. During the operation of the car with such gasoline, there is a risk of formation of oily sediments. After that, it should not be a question if you need to adapt the throttle.

As a rule, if the piston group is experiencing some problems, then the characteristic feature is to lock the flap with soil with oily impurities. Sometimes this indicates clogging of ventilation of crankcase gases.

Signs of clogging valve

When clogging the throttle, the engine begins to work in unstable mode. Characteristic features of the manifestation of a malfunction in this case are:

• increased idling;
• belated engine response to press the accelerator pedal;
• during the movement of the car, jerks are observed, and sometimes the vehicle is independently, without the participation of the driver, changes the speed;
• sharp release leads to stopping power plant.

In some cases, the Check indicator lights up on the dashboard. Sometimes resinous sediments settled on the throttle roller, which leads to it. Then the gas pedal is pressed with a noticeable effort.

Before switching to solving the problem, how to adapt the throttle on the "Skod" or any other car, it is necessary to make sure the diagnosis is accuracy by conducting a visual inspection of the mechanism. To do this, you need to remove everything you can, in order to open access to the module. Should show attentiveness to accidentally not disconnect

Cleaning DZ.

If the reason for the unstable engine operation is a dirty damper, it is necessary to move to its cleaning. For this you can contact a reliable service station. Among the large number of workshops, you can find the one that specializes in concrete stamps (Audi, Volkswagen, Toyota, Mercedes and others). However, the owner can do all the work independently, since much experience and skills are not required in this matter.

At maintenance stations, the cost of the procedure may depend on a number of factors:

• the complexity of work - in some cars for access to DZ, the dismantling of many parts will be required;
• the service level is as a rule, the larger the organization, the more expensive;
• area information - in large megalopolis, you can leave more money than in the periphery.

Purification of the DZ is a simple procedure, after which it is usually necessary to think about how to adapt the throttle on the "Nissan" or any other car.

Any car owner can perform this procedure independently. There are no special knowledge and skills here. Everything you need to get to the flap is tools and rags (better soft). Also, do not do without a special means - mostly uses the cleaner for the carburetor "Carbcliner" (Carb Cleaner).

Independent procedure for cleansing

If the flap with an electronic drive, then it is better to remove the negative battery terminal. Next, everything can be done by simple instructions:

• dismantle the air filter, for what to spin the clamp pipe;
• disconnect all throttle module connectors and other nozzles;
• push off the air filter receiver to the side so as not to interfere, and start cleaning the damper;
• upon completion, assemble the damper module in the reverse sequence, checking whether everything is in its place;
• after assembly, start the engine and check the idle speed.

In some cases, before starting to adapt the throttle on the "Toyota", "Nissan" or "Skoda", it is necessary to remove the throttle itself, which allows you to fully clean the damper. This will require a hexagon of 5 mm to unscrew the 4 fasteners. Remove the choke should be with great care, since there is a risk of damaging the gasket.

If after cleaning the DZ, elevated speeds are observed at idle, it means that you need to adapt the damper. About what it is, further in the topic of the article.

The need to adapt DZ.

Under this definition, the operation (or training) is understood, which is carried out in order for the ECU "knew", in which position is the throttle to the degree of pressing the accelerator pedal. This procedure is simply necessary in case of unstable engine operation at idle.

Most cars brand "Toyota", "Lexus", "Mercedes", "Nissan", "Audi" adapt the throttle must, as it allows you to eliminate a malfunction. The procedure is performed in the following cases:

• with a critical fall of the on-board network voltage (the battery disconnected or completely discharged);
• replaced the ECU;
• the damper with the removal of the throttle was performed;
• when replacing the throttle module itself;
• the accelerator pedal was replaced, as a rule, electronic.

It is worth noting that due to the layer of dirt, the gap is changing between the DZ and the body, and after cleaning the flap, its position has changed. But about this, the ECU "does not recognize" and continues to lead the supply of fuel according to previous testimony (before the cleansing operation). Adaptation will completely eliminate this space and restore the engine performance.

The simplest way to adapt

Now the question is whether it is necessary to adapt the throttle after cleaning, it should not be exactly necessary if there are still doubts. The easiest operation is to carry out a simple discharge only to start it is worth warmly warm up the engine to the operating temperature, for which make a small trip. Then, stopping the motor, disconnect the minus terminal of the battery and wait. Depending on the brand of the car, the waiting time can be 10-30 seconds or 15-20 minutes.

During this period, all parameters of the ECU should be returned to the original (factory) settings. Next, it remains to be connected to the terminal and start the engine - the turns must be normalized.

Adapting on the example of some cars

Another way, which we consider on the example of one famous German brand, also implies adaptation without a computer. Here you should warm the engine to a temperature of about 70-99 ° C. The battery voltage must be at least 12.9 volts with a non-working engine. The scheme of action as to how to adapt the throttle on "Volkswagen", will be approximately as follows:

• Warming up and muffled the motor, you should wait a small gap (5-10 p.).
• When the gas pedal is released, turn on the ignition and wait 3 seconds.
• After 3 seconds, it is necessary to click on the accelerator pedal 5 times until you stop and release back. Act quickly, as it is given only 5 seconds.
• After the 5th exercise it is worth waving a pause.
• After 7 seconds, press the pedal again until it stops and keeping in this position until the "Chek" indicator will flash (≈ 10 s.), Then it should be buried constantly (yet ≈ 20 p.).
• When the indicator will burn constantly, to take up to three and only after that let go of the pedal.
• Make the engine launch (repeat if necessary), wait a pause of seconds 20, then slightly gazal (2000-3500). If the XX tachometer shows 700 revolutions (+ - 50), it means that the adaptation is performed successfully.

At the same time, it is necessary to accurately adhere to the time intervals of each setting step. Only that ECU's training will be smooth. But before this it is worth studying the features of adaptation and the possibility of manual procedure for its car. Perhaps only experts hundred will be able to help.
