Engine Oil Rifle Pressure 1 Sensor Circuit


Circuit Description


The engine oil rifle pressure 1 sensor is used by the ECM to monitor the lubricating oil pressure. The ECM monitors the voltage on the signal pin and converts this to a pressure value.


Component Location


The intake manifold 1 pressure sensor is located in the air intake. Use the following procedure for a detailed component location view. Refer to Procedure 100-002 in Section E.

Shop Talk


The engine oil rifle pressure 1 sensor shares supply and return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Before troubleshooting Fault Code 141, check for multiple faults.


Possible causes of this fault include:


  • Signal circuit open or shorted to ground in the engine harness or sensor

  • Supply wire open or shorted to ground.


Refer to Troubleshooting Fault Code t05-141.
