Oil Pressure Sensor: Description and Operation
The IPC uses the engine oil pressure sensor signal to determine the engine oil pressure. The
oil pressure sensor signal circuit is solely dedicated to the IPC. The engine oil pressure sensor signal to the IPC is a variable resistance ranging from
0 - 90 Ohms. A sensor resistance of
1 Ohm will display as
0 psi (
0 kPa) and a resistance of
88 Ohms will display as
80 psi (
550 kPa).
