Oil Pressure Sensor: Description and Operation

The engine oil pressure sensor is a solid state transducer. The engine oil pressure sensor sends oil pressure information to the PCM. The PCM then transmits the oil pressure information to the IPC via serial data.

Engine oil pressure is displayed on the scan tool in volts. A low voltage reading indicates low oil pressure. As the oil pressure increases, the voltage level also increases. The normal range of the engine oil level sensor signal voltage is 0.5 Volts at 0 kPa (0 psi) to 4.5 Volts at 883 kPa (128 psi).
