What's wrong with the EPC displayed on the car? The EPC light is on, the vehicle shakes, and the throttle does not go.

The car display EPC indicates that the electronic stability system of the engine in the car may be faulty. The most common reason is that the electronic throttle is too dirty and the engine has too much carbon, which leads to the insensitive response of the sensor. It is recommended to clean the throttle every 20,000. The accelerator pedal position sensor fails and the sliding rheostat changes; The throttle circuit is aged and rusted; The brake light bulb of Volkswagen model is damaged, which will also cause the EPC fault light to light up.

The EPC light is on, the vehicle shakes, and the throttle does not go.

When the EPC light is on, the vehicle shakes and the throttle does not go, indicating that the engine management system or electronic control is out of order at this time, which is generally caused by poor oil quality or unclean throttle. It is necessary to change to higher purity gasoline and clean the throttle; In Volkswagen models, the most common reason is that the brake lights are not on, and it is necessary to replace the light bulb or check the brake switch and wiring.

Since the inspection of EPC system fault requires a special decoder, the owner should contact the trailer in time and drag it to the repair shop for electronic troubleshooting and maintenance.

Measures to prevent EPC indicator light from lighting:

1. When the car travels to a certain kilometer, it should be maintained in time and the throttle should be cleaned every 20,000 kilometers. If you run at idle speed for a long time (such as turning on the air conditioner for a long time or traffic jam) or rarely run at high speed, you should maintain it in advance to ensure the best performance of the car and eliminate the EPC fault light caused by engine carbon deposition.

2. The gasoline used in the car should be of the purity specified in the car manual. Appropriate gasoline can effectively reduce the carbon deposition of the engine and ensure the maximum driving power of the car.
