Hva betyr feilkoden?
The control module checks the PWM signal from the accelerator pedal position sensor. The fault code is set when the signal frequency is incorrect.
Mulige årsaker
- Loose or high-resistance connections on the PWM signal wire
- Interference on the PWM signal cable
- Damaged accelerator pedal position sensor
Hva du kan gjøre
- 1Read the fault code status with the ignition on. Check that the fault is not active when the test is finished, then clear the code
- 2Check the PWM signal wiring at the pedal and at the control module: the connections should be firmly seated and free from contact resistance
- 3Check whether anything could disturb the wire, such as chafing or running close to live cables
- 4If the connections are in order and the fault remains, have a workshop check or replace the accelerator pedal position sensor
Symptomer du kan merke2
- A message is shown in the information display
- The accelerator pedal is ignored during braking
Hva feilen kan påvirke2
- The control module uses the analogue signal via CAN instead
- If the brake is pressed at the same time, the pedal position used is the released position
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
