Oil Pressure Sensor
The oil pressure sensor is installed into the engine oil filter adapter. The oil pressure is calibrated to close between 26-44 kPa (3.8-6.4 psi).
The engine oil pressure sensor is threaded into the cylinder block. The oil pressure sensor reacts to the pressure of the engine oil in the lube
passage. It is normally closed with engine oil pressure and opens with low oil pressure.
