Throttle adaptation is an important step in improving engine performance.


The throttle valve is an integral part of the intake system of all gasoline internal combustion engines without exception. Its main function is to regulate the amount of air entering the car’s engine with the subsequent formation of an air-fuel mixture.

The throttle body is installed between the intake manifold and the car’s air filter. Essentially, the throttle valve acts like an air valve. When the throttle valve is open, the pressure in the intake system corresponds to the atmospheric pressure of the environment. If the damper is in the closed position, the pressure is reduced until a vacuum is created. This property of the shock absorber is often used when the vacuum servo is used in the brake system of a car. This function is also used to purge the canister in the gasoline vapor recovery system.

Given the 2 possible throttle states, every car owner should know how to determine the current position of the part. To do this, there is a procedure called throttle adaptation. The essence of this process is to obtain information about the size of the gap at a particular point in time between the shock absorber and the throttle body. Based on the data obtained, the car owner will be able to obtain more complete information about the state of the resistive layer of the potentiometer, which wears out due to prolonged idling of the engine. Wear and tear often causes the engine to stop, which is a wake-up call for any car owner.

Throttle adaptation is an important step in improving engine performance.

After the motorist is convinced of the need to adapt the throttle, you can proceed to the direct implementation of this process. Just want to clarify that this work does not require much experience. However, like other types of diagnostics, it requires a responsible approach and the ability to wait.

In order for the throttle adaptation not to be interrupted in the middle of its implementation, everyone should have the equipment with them. Its list depends on the year of manufacture of the car.

If the car was produced before 2004, then for successful adaptation it is quite possible to get by with the usual K Line adapter. If the vehicle was built later, a CAN compatible VCDS adapter is required for throttle adaptation. The adapter comes with a program that adapts and informs us about the status of the operation.

Another important procedure, without which it is strictly forbidden to start fitting, is flushing the throttle. To do this, experts use the ABRO Carb & Choke cleaner, which perfectly removes dirt. To get to the car door, you need to remove everything that could interfere with us in this difficult matter. If your car has an AWT engine under the hood, removing the shock absorber will not be difficult for you. But if you have a car with an ADR engine, where the shock absorber is closer to the cab, removing it will require cleaning all the pipes. Having taken out the throttle valve, we take the can and the tube in our hands and thoroughly rinse the valve. At the end of this, we mount the motor in the reverse order. We start the car to make sure the assembly is correct.

2 Procedure for throttle adaptation

After you have identified the necessary equipment and thoroughly flushed the throttle, you can proceed to connect the electronics and perform adaptations. To get a clearer idea of ​​the sequence of actions, it is better to describe the landing in the following algorithm:

  1. Connect one end of the K Line / VCDS diagnostic adapter to a special connector on the car, and connect the other end of the cable to the laptop connector;
  2. Turn on the car ignition and run the program supplied with the adapter;
  3. On the laptop, the program menu should be highlighted, with which we will begin the adaptation process;
  4. In this case, using the "select" action, press the "01" (engine) key. Then press the button "04" (basic settings). If your vehicle’s throttle is electrically operated, press the "60" button. If the damper is cable operated, select channel "98";
  5. After following these steps, you will notice how the percentages are performed on the laptop display. In addition, the message “Adaptation in Progress" will appear on the screen;
  6. After a few seconds, the message “Adaptation OK” will appear, which means that the operation was successful;
  7. The last step is to turn off the ignition and check for errors. To check if the adaptation was successful, run the program again. Of course, we turn on the ignition of the car.

Throttle adaptation is an important step in improving engine performance.

It often happens that the diagnostics we need is not carried out even after a thorough flushing of the throttle valve. If the reason is only in the potentiometer, you can safely throw it away. Another reason for an unsatisfactory landing is insufficient engine force to close the damper during the initial landing phase. In this case, the motor will need your immediate help: press hard on the special "tongue" associated with the axle. After several repetitions of this movement, the engine will definitely return to normal.

Among the masters there are those who do not remove the accelerator, but immediately use a brush and solvent. In these cases, adaptation very often does not occur the first time. The injection system, on the contrary, begins to "gather dust". In these cases, it may be useful to set up the system using a scanner. You need to set an angle of 13 degrees on it, the idle speed can be set as you like.

Throttle adaptation is an important step in improving engine performance.

If throttle adaptation has already been done before and you suddenly decide to flush the throttle as a preventive measure, then know that after flushing the adaptation should be repeated. If you ignore this need, it is quite possible that you will not be able to start the car and at idle it will simply “float”. These difficulties will accompany the car owner for about a week, but then the problem will disappear by itself.

3 Reset damper adaptation: how and why?

Any self-respecting car owner should be able to not only be able to adapt the throttle setting, but also to restore adaptation. Recovery is not difficult for anyone. Consider this operation in more detail in the form of an algorithm of actions:

  • turn on the ignition, but do not start the car itself yet;
  • wait for all devices and sensors to turn on, then wait another 90 seconds;
  • we start the car.

With these simple steps, you can restore the adaptation of shock absorbers on cars of any type and year of manufacture.

Throttle adaptation is an important step in improving engine performance.

Many unfortunate car enthusiasts may wonder why they should be dropped, because with an adapted throttle, the car rides much better than before. There are several answers to this question:

  • first of all, the reset must be carried out immediately after buying a used car, because who knows how the former owner treated the car before you;
  • be sure to restore after some types of repairs;
  • check the operation of the gearbox;
  • every time after the winter period;
  • and finally, restoring the fit can only be done out of curiosity to feel the difference.

Throttle adaptation is an important step in improving engine performance.

As you can see, there are reasons for recovery, and they are more than burdensome. And the need to restore adaptation should not be forgotten, just as about the adaptation itself. In any case, remember that the car is your best friend on the road. And from what interest you treat it, its functionality and efficiency will depend.
