What is the reason for the low temperature and bright epc in winter?

The EPC fault light is always on, indicating that there is a fault in the engine management system or electronic control, which is often accompanied by unstable idle speed of the vehicle or engine cold start jitter. But for domestic car owners, it is generally caused by domestic oil quality and dirty environment inside the car. Drive to the maintenance station as soon as possible for maintenance. Generally, cleaning the throttle can solve the problem.

Introduction of EPC

When the ignition switch is turned on for function check, the indicator EPC will light 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. Under normal circumstances, dirty throttle body, vacuum leakage of intake system, broken brake switch and untimely engine upgrade may all lead to EPC failure.

The automobile epc lamp represents the electronic throttle, which is generally common on Volkswagen models. When the epc light is on, it indicates that the electronic throttle system may be faulty. The fault of electronic throttle may affect the normal use of the vehicle, which requires the owner to deal with it in time to avoid other faults.
