Hva betyr feilkoden?
The engine control module monitors the EVAP valve. The fault is set when the control module registers a fault in the control of the valve, here in the form of a signal that is too low. The fault may lie in the connector or in the wire that is shorted to ground.
Mulige årsaker
- Signal wire short-circuited to ground
Hva du kan gjøre
- 1Read out the fault code, erase it and road-test to see whether it returns
- 2Switch off the ignition and check the connector to the EVAP valve for looseness, contact resistance and oxidation
- 3Use a multimeter to check that the signal wire from the valve is not shorted to ground
- 4Look for chafing on the signal wire where it runs near the body or any earthed metal part
- 5If the fault remains, have a workshop with diagnostic equipment check the valve and its wiring
Symptomer du kan merke1
- The malfunction indicator lamp (MIL) is lit
