Hva betyr feilkoden?
The engine control module checks both the PWM signal and the sensor's analogue signal. The code is stored when the PWM signal has too low a frequency or stays low for too short a part of each cycle, and the cause can be poor contact, a short-circuited signal cable or a damaged sensor.
Mulige årsaker
- Contact resistance or oxidation in the connectors
- Signal cable short-circuited to voltage or ground
- Open circuit in the signal ground cable
- Damaged accelerator pedal position sensor
Hva du kan gjøre
- 1Check that the fuses are intact. Their locations are given in the owner's manual or on the inside of the fuse box cover
- 2Test the relevant functions during a test drive to see whether the symptoms are present now
- 3Check the connectors at the accelerator pedal for oxidation and contact resistance, and look for chafing or pinching in the pedal wiring
- 4Use a multimeter to check that the signal ground wire to the pedal is not broken
- 5Have a diagnostic tool? Read the pedal signal in live data while you press and release the pedal, and check whether it drops too low or disappears
- 6If the fault returns, have a workshop check the pedal sensor and the wiring
Symptomer du kan merke2
- Text message and warning symbol in the display
- The car performs poorly and lacks power
Hva feilen kan påvirke1
- Engine torque may be limited
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
