What is the reason why the epc lamp of Jianghuai diesel vehicle can't refuel?

Generally speaking, EPC lights have two possibilities. 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.

The EPC of automobile is also the electronic stability system of engine. EPC lights are on mostly because the electronic control part of the engine is out of order or some physical reasons lead to abnormal data of the electronic control system. EPC light is yellow, which is a reminder indicator. At this time, the vehicle can still drive.

Keep driving at a low speed and drive to the maintenance point as soon as possible to troubleshoot. As far as domestic models are concerned, the reasons that cause EPC lights to light up are throttle carbon deposition, brake light failure, air leakage in intake pipe, brake switch failure and so on. In addition, insufficient battery power, poor oil products or wrong model may also cause EPC to turn on normally.

Throttle carbon deposition is the main reason why EPC lights are on, and cleaning the throttle is a maintenance item that most 4S shops will have when EPC lights are on, so 4S shops also recognize that throttle carbon deposition is one of the main reasons why EPC lights are on.
