The electronic throttle sensor is broken. What are the symptoms of diesel vehicles?

The electronic throttle sensor is broken, so the fuel can't be added, and the throttle is stuck intermittently. 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. But when the sensor is broken, it can't generate the throttle opening signal to the computer, and the computer only injects fuel according to the intake air at idle speed.

Common faults of electronic throttle and their elimination methods are as follows:

1. Loose or poor contact of the accelerator pedal position sensor or the plug on the accelerator pedal position sensor of the electronic accelerator system will interrupt the signal transmission between the computer and the accelerator pedal position sensor or the accelerator position sensor, thus lighting the warning light (EPC) of the electronic accelerator system, and the accelerator pedal will feel empty; Slippery sensor;

2. When one accelerator position sensor is damaged and the system uses the signal of another sensor, and the response to the accelerator pedal remains unchanged, there will only be acceleration weakness, shift impact, cruise system shutdown, EPC light on and fault code storage; Slippery sensor;

3. The throttle of a vehicle equipped with an electronic throttle is too dirty, usually because there is too much carbon deposited on the inside of the throttle, which will cause the EPC light to light frequently, and the vehicle will suddenly turn off and shake all the time while driving. Remove the throttle valve, thoroughly clean it, and then re-match it to eliminate the fault.
