Was bedeutet der Fehlercode?
The engine control module (ECM) monitors the bypass valve signal in the thermostat housing. If the signal is too low, the code is set. The cause may be poor contact, or an open circuit or short to ground in the signal wire.
Mögliche Ursachen
- Contact resistance or oxidation in the connectors
- Open circuit or short to ground in the signal wire
Was Sie tun können
- 1Read the code, clear it and road test the car to see whether it returns
- 2Check that the connector at the bypass valve is fully engaged and free from oxidation and contact resistance. No rust solvent spray or grease
- 3Use a multimeter to check that the signal wire has no open circuit or short to ground
- 4If the fault returns after clearing and a road test, and no cause is found, have a workshop replace the bypass valve
