Was bedeutet der Fehlercode?
Even though the code is named over temperature, it concerns the signal wire to valve 2 in the cooling circuit, which the engine control module (ECM) monitors. The code is set when the signal wire is shorted or has an open circuit, and then cooling of the drive components may stop.
Mögliche Ursachen
- Mechanical fault on the valve
- Electrical fault on the valve
- Short circuit or open circuit in the wires to the valve

- 3Use a multimeter to check that the signal wire to valve 2 has no break and no contact with ground (the body)
- 4Have a workshop check valve 2 if the fault remains after these checks
Symptome, die Sie bemerken können2
