Hva betyr feilkoden?
The engine control module receives no signal from the EVAP valve and therefore sets the fault code. The fault can be caused by open circuits in the wiring, poor contact in the connector or a damaged valve. While the fault is present, the control with two oxygen sensors is disabled.
Mulige årsaker
- Open circuit in the signal wire
- Open circuit in the supply wire
- Contact resistance in the connections
- Damaged EVAP valve
Hva du kan gjøre
- 1Check the EVAP valve connector for contact resistance and oxidation
- 2Look for chafed or broken wiring to the EVAP valve
- 3Check the fuse for the circuit
- 4Have you got a diagnostic tool: activate the EVAP valve with the ignition on and listen for a click when it opens
- 5Have a workshop measure the EVAP valve resistance and replace the valve if it is damaged
Symptomer du kan merke1
- Malfunction indicator lamp (MIL) is on
Hva feilen kan påvirke1
- Control with two oxygen sensors is disabled
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
