What is the reason for the failure of the new Ming Rui e pc?

The failure of epc in new Ming Rui is due to the failure of electronic throttle system, which will affect the normal use of vehicles. 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. Also, due to the oil problem, the EPC fault light will also light up.

Basic principles:

Gasoline engines generally use electronic throttles. In order to meet the requirements of three-way catalytic conversion of gasoline engines, the air-fuel ratio should be kept around 1.

In this way, the fuel injection quantity is required to be proportional to the throttle opening, and the on-board computer will find the fuel injection quantity in this case through calculation or table lookup according to the throttle pedal opening collected by the sensor, so that the air-fuel ratio of the engine can meet the requirements. That is to say, the power of the engine is indirectly controlled by controlling the opening of the electronic throttle of the engine.
