What does it mean to show epc on the dashboard?

Epc is the electronic power control system of engine, also called electronic throttle. The reason why ecp is displayed on the dashboard of the automobile is that the sensor or control unit of the automobile electronic stability system is out of order.

Why does epc light up:

The unclean throttle causes the epc fault light on the instrument panel to light up, so it is necessary to clean the throttle in time.

The epc fault light on the dashboard lights up due to system false alarm or accidental fault, and it needs to be sent to the 4s shop to check whether there is any fault in the internal circuit of the car.

The quality of the fuel used by the car is not up to standard, which leads to the epc fault light on the dashboard, and it is necessary to replace the high-quality fuel.

Working principle of epc:

In epc system, the sensor of pedal device replaces the previous throttle line, and the engine control unit (ecu) can calculate the optimal target throttle opening according to the position data fed back by the sensor of pedal device, and send a signal to the throttle drive motor to rotate the throttle to this angle.
