Volkswagen epc explains what is wrong.

Volkswagen epc shows that the electronic throttle is faulty.

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine. Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic.

Epc shows that the throttle body is dirty and there is too much carbon deposit; Air intake system failure, such as leakage or poor blockage; Fuel selection is not up to standard.

Cleaning and maintenance methods of cleaning throttle valve:

1. If there is a plastic heat shield on the engine, it needs to be removed first.

2. Remove the engine hood, and the throttle can be seen under normal circumstances. There are some air pipes around the throttle, which need to be removed, and the position of each pipe should be clearly recorded.

3. After removing the air pipeline on the throttle, you can remove the whole throttle.

4. The side of the throttle near the combustion chamber is generally dirty with traces of black carbon deposition, which is the main part that needs cleaning.

5. Cleaning the throttle is mainly to remove carbon deposits on it, and special throttle cleaning liquid or cleaner can be used. It should be noted here that the cleaning principle of this cleaning agent is to dissolve carbon deposit, and its composition is harmful to human body. It is best to wear gloves and masks when cleaning.

6. Spray the cleaner to the position with more carbon deposits on the throttle, and wait for about 5 to 10 minutes to dissolve the carbon deposits. Using brushes can speed up the removal of carbon deposits.

7. When you see that the stain on the accelerator has completely dissolved, you can wipe the detergent inside the accelerator with a clean towel.

8. Install the cleaned throttle valve on the machine body according to the original position, and then install all air pipelines to complete the whole process of cleaning the throttle valve. After all the hardware is installed, throttle needs to be initialized.
