Just light the epc light and then light it.

EPC system is called engine electronic throttle system, which can also be referred to as electronic throttle system for short. The system consists of engine adjusting unit, engine wiring harness, throttle, accelerator pedal, brake switch and manual transmission clutch switch. When the EPC light is on, the vehicle will shake and vibrate and often break down. The main reasons include too much carbon deposit in the throttle valve and the problem of opening; Engine misfire and cylinder loss affect the abnormal operation of throttle valve; Air leakage at the rear of the throttle causes abnormal detection data of the intake pressure sensor. These conditions will basically light the EPC lamp. If the vehicle has the above problems, you can stop first and turn off the ignition switch. After restarting the engine, if the fault light goes out, it is an unexpected fault problem. At this time, you can continue driving and go to the maintenance agency for maintenance as soon as possible. However, if the fault indicator does not go out after restarting the engine, it means that the fault still exists and you should drive at the same place or at a low speed. If there is no response behind the refueling door, try to avoid driving. If the throttle and engine acceleration are basically normal, you can continue driving and go to the maintenance agency for maintenance as soon as possible.
