Can epc light be turned on when the vehicle is shaking?

When the EPC light of Pacific Auto Network is on, if the vehicle shakes, it will not be able to continue driving. The English name of EPC is ElectronicPowerControl, which means electronic adjustment of engine power (electronic throttle), and is often used in Volkswagen series. This light indicates that the electronic throttle system may be faulty, which may affect the normal use of the vehicle.

There are many reasons for vehicle jitter when EPC light is on, and the most likely reason is that the exhaust gas recirculation valve of the vehicle has failed. When the exhaust gas recirculation valve is stuck in the fully open position, the vehicle will emit black smoke, accompanied by weak acceleration, unstable idle speed, increased fuel consumption and insufficient power. The EPC fault light on the instrument panel will light up.

In addition to the exhaust gas recirculation valve, there may be the following reasons: 1, the throttle body is dirty and there is too much carbon deposit. 2, air intake system failure, such as leakage or blockage. 3. Abnormal cylinder pressure and poor working conditions. 4. The fuel selection is not up to standard. 5. If the engine is turned off due to improper operation, this indicator light will also light up and go out after re-ignition, indicating that everything is normal. 6. Accidental failures and false alarms.

One of the more common is that the throttle is dirty. Specifically, you need to go to a 4S shop or a professional auto repair shop in time to find out why. Only when the specific cause is determined can the symptoms be repaired.
