What is the phenomenon that the accelerator of the car is broken?

If there is something wrong with your car, the mechanic tells you that there is something wrong with the accelerator of your car and it needs to be replaced. So under what circumstances do you need to change the throttle? The following are some common causes of throttle damage:

1. If the throttle valve is broken, the EPC light on the instrument will light up. This indicates that there is something wrong with the electronic throttle control system.

It is not easy to start the cold car, and it is also difficult to stop at the valve. Idle speed is unstable. Black smoke.

3. The vehicle can't be started, the diagnostic instrument checks, and the engine system reports that the throttle valve is damaged or the sensor is unreliable.

When the vehicle taxies, it is usually closed.

5. Measure the throttle opening with a diagnostic instrument to see if it is within the normal range. If the throttle angle is still too large after cleaning the throttle, the throttle needs to be replaced.

6. The basic setting of throttle valve was unsuccessful. After troubleshooting the wiring, battery and engine control unit, the throttle valve needs to be replaced.

The above are the common manifestations of vehicle throttle damage. Of course, there are other external factors that can also cause throttle damage. In this case, it is necessary to drive the vehicle to the 4S shop or repair shop for inspection to determine what caused it.
