EPC is the full name of engine electronic stability system, and many people also call it electronic throttle. The system consists of some sensors, controllers and other components. When the sensor fails or senses an abnormal situation, the control system will take corresponding measures according to the set program.
The EPC fault light is always on, indicating that the engine management system or electronic control is out of order, which is often accompanied by unstable idle speed of the vehicle or engine jitter during cold start. However, for domestic car owners, it is generally due to the quality of domestic oil products and the dirty environment in the car, so they should drive to the maintenance service station as soon as possible for maintenance. When the ignition switch is turned on for function check, the indicator EPC will light up.
