    Hva betyr feilkoden?

    Normal engine control reads the throttle position sensor signals as beyond their lower or upper limits, whereas the internal monitoring interprets them otherwise. The code is then set.

    Mulige årsaker

    • Damaged engine control module (ECM)

    Hva du kan gjøre

    1. 1If you have a diagnostic tool: read the throttle position value in live data while the pedal is pressed and released, and see whether it follows the movement
    2. 2Clear the code and test drive the car to see whether it comes back
    3. 3For a permanent fault the engine control module is replaced, which a workshop does

    Symptomer du kan merke4

    • Low maximum engine speed
    • Cruise control does not work at all
    • Uneven idle
    • Malfunction indicator lamp lit

    Hva feilen kan påvirke1

    • Engine speed and torque are limited to a calculated reasonable value

    Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
