Hva betyr feilkoden?
The engine control module monitors the injector output stages and how long each injection lasts. If the injection time for one of the valves is wrong, the code is set. The last digit of the code shows which cylinder is concerned, here cylinder 1.
Mulige årsaker
- Contact resistance, oxidation or poor contact in the connections
- Open circuit in the signal cable (+)
- Open circuit in the signal cable (-)
- Damaged injector
Hva du kan gjøre
- 1Read the codes and clear them, road test and see whether the code returns
- 2Check the connector on the injector for cylinder 1 for play, contact resistance and oxidation
- 3Use a multimeter to check the two wires to that injector for breaks and for short circuits to ground or supply voltage
- 4If the code returns after clearing and a test drive with no fault found, have a workshop check and, if needed, replace the injector
Symptomer du kan merke2
- The engine lacks power and runs poorly
- A message and a warning symbol appear in the display
Hva feilen kan påvirke2
- Engine speed is limited
- The car can be driven in limp-home mode
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
