What is the fault of epc lamp and how to solve it?

When the EPC (Electronic Power Control) light and the engine light of an automobile are on at the same time, it usually indicates that there is something wrong with the engine or electronic system. EPC light indicates electronic power control system failure, and engine light indicates engine system failure.

The main reasons for the failure of automobile EPC light;

1, 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. But for domestic car owners, it is generally caused by domestic oil quality and dirty environment in the car. Drive to the maintenance service station as soon as possible for maintenance, and generally clean the throttle.

2. When the ignition switch is turned on for function check, the indicator EPC will light up. If the indicator lights up while driving, it indicates that the engine power electronic control system is out of order. The engine must be checked immediately. 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.

3. When the EPC light is on, there are two possibilities. First, the throttle is dirty and needs cleaning. In another case, the brake lights don't work. Replace the light bulb or check the brake switch and wiring. Also, due to the oil problem, the EPC fault light will also light up.

In order to determine the specific problem, it is recommended that you immediately send the vehicle to a professional garage for diagnosis and maintenance. They will use the fault diagnosis tool to read the fault code of the vehicle and find the root of the problem. Solving the problem as early as possible can ensure your driving safety and avoid more serious injuries.
