Mai Rui Bao xl accelerator pedal sensor failure

There are many reasons for the failure of the accelerator pedal sensor, which are generally manifested as refueling failure, intermittence and throttle sticking. When a fault occurs, it should be checked immediately to find out the cause of the fault. The function of the accelerator pedal sensor is to sense the depth of the accelerator pedal and send the signal to ECU to control the accelerator opening.

Common faults include: the harness of the accelerator sensor is broken, the connector falls off, one signal fails, the ratio of the two signals does not meet the requirements, the throttle opening conflicts with the brake pedal logic, and ECU thinks that the signal of the accelerator pedal sensor is faulty. If the fault light is on, a fault code will be generated, the throttle will fail and the engine will limp.

Steps for fault detection of accelerator pedal position sensor:

1. Remove the accelerator pedal assembly.

2. Locate the accelerator pedal sensor.

3. Find the signal output line corresponding to the accelerator pedal sensor.

4. Use a multimeter to measure the line.

5, pull the accelerator pedal, at the same time observe the change of multimeter measurement, in order to judge whether the fault.

6. Different models need to be measured according to their standard measurement steps. Please refer to the maintenance manual.

If the accelerator pedal sensor fails, it should be handled in time. If you can't judge the reason for the failure, you should go to the 4S shop as soon as possible. (Photo/Text/Photo: Li Linwei) @20 19
