Hva betyr feilkoden?
The control module receives no signal from the EVAP valve in the evaporative emission system. The cause is an open circuit in the signal wire or the supply wire to the valve. Without a signal, the control module cannot monitor how the valve is working.
Mulige årsaker
- Open circuit in the signal wire to the EVAP valve
- Open circuit in the supply wire to the EVAP valve
Hva du kan gjøre
- 1Check that the fuse for the circuit is intact. Their locations are shown in the instruction manual or on the fuse box cover
- 2Switch off the ignition and unplug the EVAP valve connector. Check the connector for looseness, contact resistance and oxidation
- 3Use a multimeter to check that the signal and supply wires to the valve have no open circuit
- 4Look for chafed wires to the EVAP valve, especially where they run near mounting points and moving parts
- 5If the fault remains, have a workshop with diagnostic equipment check the valve and its wiring
