Engine Oil Rifle Pressure 1 Sensor Circuit

Circuit Description

The engine oil rifle pressure 1 sensor is used by the engine control module (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 135, check for multiple faults.

Possible causes of this fault code include:

  • Open return circuit in the harness, connectors, or sensor

  • Signal circuit shorted to sensor supply or battery voltage.

Refer to Troubleshooting Fault Code t05-135.
