Hva betyr feilkoden?

The engine control module monitors the control of the EVAP valve, and a signal that is too high is interpreted as a fault. The cause is a signal wire to the valve that is shorted to voltage.

Mulige årsaker

Signal wire short-circuited to voltage

Hva du kan gjøre

1Read out the fault code, erase it and road-test to see whether it returns
2Switch off the ignition and unplug the EVAP valve connector. Check the connector for loose connections and oxidation
3Use a multimeter to check that the signal wire is not shorted to voltage
4Look for chafed wires that may have touched a live 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
