Circuit Description
The oil pressure/temperature sensor is used by the electronic control module (ECM) to monitor the temperature of the engine oil. If the oil temperature becomes too high and the engine protection is enabled, a derate condition can be incurred, possibly leading to shutdown.
Component Location
The oil pressure/temperature sensor is located on the engine block to the left of the fuel filter, behind the air compressor.
