Hva betyr feilkoden?
The engine control module monitors the accelerator pedal position sensor and stores the code when it registers faulty signals from it, here on circuit 2. The fault can be caused by an open circuit, a short to ground or to battery or reference voltage, or a damaged sensor.
Mulige årsaker
- Open circuit in the signal cable
- Signal cable short-circuited to ground
- Signal cable short-circuited to battery voltage or reference voltage
- Damaged accelerator pedal position sensor
Hva du kan gjøre
- 1Work through the other engine control codes first, and clear this code last
- 2Inspect the wiring to the accelerator pedal sensor for chafing, pinching and breaks
- 3Check the connectors at the pedal for play, contact resistance and oxidation
- 4Use a multimeter to check that the signal cable is not in contact with ground or battery voltage
- 5Have a diagnostic tool? Read the circuit 2 pedal signal in live data while you press and release the pedal, and see whether it drops out
- 6If the wiring is sound but the fault remains, have a workshop replace the accelerator pedal position sensor
Symptomer du kan merke1
- The malfunction indicator lamp (MIL) comes on
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
