Just restart when the epc light is on. What is the situation?

It is normal to restart after the epc light is on. After the ignition switch is turned on, the fault light will go out after the system checks that there is no fault. In EPC system, the original throttle line is cancelled and the engine control unit is replaced by the sensor of pedal device. According to the position data fed back by the sensor of the pedal device, the optimal target throttle opening is calculated, and a signal is sent to the throttle drive motor to make the throttle rotate to this angle. The following is the introduction: 1. Basic principle: Electronic throttle is generally used in gasoline engines. In order to meet the requirements of three-way catalytic conversion of gasoline engines, the air-fuel ratio should be kept around 1. This requires that the fuel injection quantity is in direct proportion to the throttle opening. The on-board computer will find the fuel injection quantity in this case by calculating or looking up the table according to the throttle pedal opening collected by the sensor and the air intake of the engine, so that the air-fuel ratio of the engine can meet the requirements. 2. Application in automobiles: Generally, automobiles are marked with EPC. After the key door is opened, the EPC indicator light will light up for a few seconds and then go out. If the vehicle does not go out after starting, it means that the mechanical and electronic system of the vehicle has failed. 3. Generally speaking, EPC light has the following possibilities: (1) The throttle is dirty: it should be cleaned. (2) The brake light is not on: it is necessary to check the brake switch and wiring. (3) Oil problem.
