Foreign exchange shows that the accelerator pedal sensor is faulty.

1. When the accelerator pedal position sensor is broken, it can't generate an accelerator opening signal to the computer, and the computer only injects fuel according to the air intake at idle speed.

2. The accelerator pedal position sensor detects how much the accelerator is depressed, and the computer controls the accelerator motor to rotate at a certain angle according to this signal to meet the air intake under various working conditions.

3. The accelerator pedal is also called accelerator pedal. It is a part of automobile fuel supply system. By controlling the amount of pedaling, the throttle opening of the engine, the air intake and the fuel consumption of the computer, the engine speed can be controlled.
