Oil Pressure Sensor Circuit

Circuit Description

The oil pressure/temperature 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 oil pressure/temperature sensor is located on the engine block to the left of the fuel filter, behind the air compressor.
