 Engine Oil Pressure Sensor Circuit
|
Circuit Description
The engine oil pressure sensor is used by the electronic 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. The oil pressure value is used by the ECM for the engine protection system.
Component Location
The engine oil pressure sensor is located on the intake side of the engine block, below and to the rear of the integrated fuel system module (IFSM). Refer to Section E for a detailed component location view.
Shop Talk
The engine oil pressure 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 in the harness, connectors, or sensor.
- Signal wire shorted to sensor supply or battery voltage.
