Epc light flashes. What happened?

EPC refers to the engine electronic power regulation system, also known as electronic throttle, which is common in Volkswagen series. EPC indicator light generally means that the electronic throttle system may be out of order, which will definitely affect the normal running of this car. After the key door is opened, the vehicle will start self-inspection immediately, and the EPC indicator light will light up for a few seconds and then go out. If the indicator light does not go out after the vehicle is started, then the mechanical and electronic systems of the vehicle have failed. Electronic throttle is an important regulating part of automobile engine, which consists of engine, throttle and speed sensor. The electronic throttle adjustment system is adopted, and the throttle opening adjustment is more accurate. After the gas enters the throttle valve, it will mix with gasoline to form a combustible mixture, and then burn to do work.
