 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.
Component Location
The engine oil pressure sensor is located on the left side of the engine block. Refer to Procedure 100-002 in Section E.
