Hva betyr feilkoden?
The engine control module monitors the movements and end positions of the throttle disc in the throttle unit, and stores the code when the adaptation of the disc positions is wrong. The fault can come from mechanical damage to the throttle disc, from the connector to the throttle unit or from the unit itself.
Mulige årsaker
- Mechanical damage to the throttle disc
- Damaged connector to the throttle unit
- Damaged throttle unit
Hva du kan gjøre
- 1Clear the code and road test the car to see whether it returns
- 2Inspect the throttle disc for damage and check that it does not stick
- 3Check the connectors at the throttle unit for play, contact resistance and oxidation
- 4Have a diagnostic tool? If it supports activation, run the throttle motor and check that the disc moves between its end positions
- 5If the above does not remedy the fault, have a workshop replace the throttle unit
Symptomer du kan merke1
