What fault light is Jetta epc?

Jetta EPC of Pacific Auto Network is the fault light of automobile electronic throttle system. The EPC light is mainly caused by the dirty throttle body, which needs to be cleaned and then matched. After the engine control unit detects the leakage of the air intake system, it will also light the EPC warning light.

Because the throttle is in a key position, it is easy to be polluted and damaged, so many minor faults in the car are related to the throttle, especially the performance and operation process of the car, such as power, start and stop, etc., which will have obvious feelings and some will also affect the normal driving safety of the car. The main symptoms of automobile throttle damage are engine jitter and unstable idle speed. The accelerator is a wearing part and needs to be replaced frequently.

The epc indicator light on the car is on, which is accompanied by the vehicle shaking, because the normal operation of the engine requires sufficient air and fuel injection. If this happens, the engine power will definitely drop, the EPC indicator light will be on, and the vehicle will shake. Throttle carbon deposition is the main factor affecting throttle operation.
