What is the reason why the epc light of the car is on?
The light indication of automobile epc is faulty, which is generally caused by two faults, one is the serious carbon deposition of throttle and the other is the fault of braking system. The following is a detailed introduction about the lighting of automobile epc fault light: 1. The constant lighting of EPC fault light means that the engine management system or electronic control fault is often accompanied by unstable idle speed of the vehicle or engine cold start jitter. Solution: This situation is generally caused by domestic oil quality and dirty vehicle environment. It can be solved by cleaning the throttle as soon as possible. 2. When the ignition switch is turned on for function check, the indicator EPC will light up. If this indicator lights up while driving, it means that the engine power electronic control system is out of order. Under normal circumstances, dirty throttle body, vacuum leakage of intake system, broken brake switch and failure to upgrade engine in time may all lead to EPC failure. Solution: The engine must be checked immediately. 3. When the EPC light is on, there are two possibilities. First, the throttle has serious carbon deposition. In another case, if the brake light does not light up, the EPC fault light will also light up because of the oil problem. Solution: the throttle valve should be cleaned. Replace the light bulb or check the brake switch and wiring.
