Hva betyr feilkoden?

Even though the code is named over temperature, it concerns the signal wire to the A/C shut-off valve, which the engine control module (ECM) monitors. The code is set when the signal wire is shorted or has an open circuit, and then the air conditioning is affected.

Mulige årsaker

Mechanical fault on the valve
Electrical fault on the valve
Short circuit or open circuit in the wires to the valve

Hva du kan gjøre

1Read the code with a diagnostic tool and see whether it is active or only stored
2Check that the connectors to the valve are secure and free from oxidation
3Use a multimeter to check that the wires to the valve have no break and no contact with ground (the body)
4Have a workshop check the valve if the fault remains
