Hva betyr feilkoden?
This code applies to the injector valve on cylinder 3, where the injection time has been incorrect. The control module has its own output stage for each injector and compares the time of every injection with the expected value. The last digit of the code shows cylinder 3.
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, clear them and road test to see whether the code comes back
- 2Check the connector on the cylinder 3 injector for play and oxidation
- 3Use a multimeter to check that the two wires to cylinder 3 are not broken and have no contact with ground or supply voltage
- 4If the code returns after clearing and a test drive and no fault is found, a workshop should try a new injector valve
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
