What's wrong with the old Pu Sang epc lamp?

The epc fault indicator light of Pacific Auto Network indicates that there is a problem with the engine electronic stability system, which is composed of some sensors, controllers and other components. There are two possibilities for EPC light to be on. First, the throttle is dirty and needs cleaning. In another case, the brake light is not on, so it is necessary to check the brake switch and wiring.

In vehicle maintenance, faults indicated by epc lights are common. If the light is on, it indicates that the electronic throttle system may be faulty, which may affect the normal use of the vehicle. The light of epc may be caused by the following reasons:
