Hva betyr feilkoden?
The accelerator pedal has two sensors, and the ECM compares them with each other. The fault code for sensor 2 is set on a fault in its signal or supply wire, or if the difference between the sensors becomes too large. The engine is then controlled by sensor 1 instead.
Mulige årsaker
- Signal wire shorted to voltage or ground
- Open circuit in the signal wire
- Defective accelerator pedal position sensor
- Supply wire shorted to system voltage or ground
- Contact resistance or oxidation in the connector
- Defective engine control module
Hva du kan gjøre
- 1Switch off the ignition and check the pedal sensor connector for play, contact resistance and oxidation
- 2If you have a diagnostic tool: press the accelerator pedal fully down and release it straight away, and check in live data that sensor 2 follows sensor 1
- 3If the fault comes and goes, it may be oxidation or poor contact, and it can appear at any pedal position
- 4If the fault remains or is permanent, have a workshop replace the accelerator pedal position sensor
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- The engine is controlled by pedal sensor 1 instead
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
