Hva betyr feilkoden?
The accelerator pedal has two sensors. The ECM monitors the power supply to sensor 1, and if that supply is faulty the fault code is set. The engine is then controlled by sensor 2 instead.
Mulige årsaker
- Power supply wire short-circuited to system voltage
- Power supply wire short-circuited to ground
- Defective accelerator pedal position sensor
- Defective engine control module
Hva du kan gjøre
- 1Switch off the ignition and check the accelerator pedal sensor connector for play, contact resistance and oxidation
- 2With a multimeter, check that the supply wire to sensor 1 is not shorted to ground or to system voltage
- 3If you have a diagnostic tool: check in live data that both pedal sensors show reasonable values and track each other as the pedal is pressed
- 4Because the engine is then controlled by only one sensor, have a workshop correct the fault
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- The engine is controlled by pedal sensor 2 instead
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
