Oil Pressure Sensor Circuit
SMALL | MEDIUM | LARGE

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.

Shop Talk

Does the fault occur only in cold weather? If so, allow the oil to warm up and see if the fault goes inactive.
