Oil Pressure Sensor: Description and Operation

Description:

DESCRIPTION
The Engine Oil Pressure (EOP) Sensor is a resistor which changes value based on pressure and is mounted to the rear left top of the engine.


OPERATION
The PCM supplies a 5 volt signal to the oil pressure sensor through a resistor in the PCM and measures the voltage on the signal circuit. By measuring the voltage, the PCM calculates the engine oil pressure.
