Introduction of epc lamp:
When the ignition switch is turned on for function check, the indicator EPC usually lights up. If this indicator lights up while driving, it indicates that the engine power electronic control system is out of order. The engine must be checked immediately. The throttle valve body is dirty, the air intake system leaks vacuum, the brake switch is damaged, and the engine is not upgraded in time. EPC failure may occur.

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.
