Centinel™ Oil Control Valve Circuit – Shorted Low
|Fault Code: 223
Centinel™ oil control valve circuit – shorted low. Low signal voltage detected at Centinel™ oil control valve circuit.
None on performance. Centinel™ system deactivated.
Centinel™ Oil Control Valve Circuit
The Centinel™ oil control valve is controlled by the ECM. The ECM sends a voltage signal to the valve which diverts a preset amount of engine oil into the fuel system to be burned.
Refer to Procedure 100-002 for a detailed component location view.
This fault is logged when the ECM commands the Centinel™ oil control valve ON and detects a lower signal voltage than expected at the output.
Possible causes for this fault include:
- Short circuit to ground in the oil control valve or engine harness.
- Faulty ECM circuit
- Low internal resistance of Centinel™ oil control valve.
