 Centinel™ Oil Control Valve Circuit
|
Circuit Description
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.
Component Location
The Centinel™ oil control valve is mounted on the intake side of the engine below and towards the rear of the air compressor. Refer to Procedure 100-002 for a detailed component location view.
Shop Talk
The Centinel™ oil control valve, turbocharger control valve, and turbocharger control shutoff valve share the same return wire in the engine harness. If Fault Codes 224, 2355, and 2277 are all active, check the return ground terminal for a faulty ground connection.
Possible causes for this fault include:
- Open circuit in the engine harness, connectors, or Centinel™ oil control valve.
- Signal circuit shorted to a voltage source in the engine harness.
