What's wrong with Ruifeng epc lamp?

Generally speaking, the throttle is dirty, just clean it. There are other reasons for epc lights. For example, there is something wrong with the brake lights. In this case, it is necessary to check whether the bulb of the brake light is faulty, or whether there is a problem with the brake switch and wiring.

If the epc fault light is on, it means that there is something wrong with the engine management system or the electronic control system. Generally, when the EPC light is on, the driver can obviously feel that the car is idling unsteadily, and the engine will shake during cold start.

In general, the main causes of epc failure are dirty throttle body, brake switch failure, vacuum leakage of intake system, untimely engine upgrade and so on.

There is another reason that can also lead to the failure of epc in China, and that is the problem of oil products. When the quality of oil is low or the environment in which cars are used is dirty, epc will also fail.

Dealing with this situation is very simple, just drive the car to the maintenance service station for inspection and then clean the throttle.
