Citroen c5 accelerator pedal sensor failure.

The failure causes of Citroen c5 accelerator pedal sensor are as follows:

1, the accelerator pedal position sensor is broken, which will lead to the uncontrollable throttle size, because the throttle does not receive the signal of the opening size, or it is not reflected at all when refueling.

2. If one or two sensor signals are interrupted, the fault memory will record the next fault and the electronic throttle fault light will turn on. Comfort functions (such as cruise control or engine torque adjustment) are turned off.

3. The two groups of resistors in the sensor can't detect each other, and the ECU can't get the correct position of the current accelerator pedal, which leads to the failure of engine acceleration. The failure of a group of resistors in the potentiometer caused the ECU to receive an error signal.
