Oil Pressure Sensor: Description and Operation
SENSOR/SWITCH-OIL PRESSURE
DESCRIPTION
The oil pressure switch is a pressure sensitive switch that is activated by the engine's oil pressure (in the main oil gallery). The switch is a two terminal
device (one terminal is provided to the wiring harness and the other terminal is the switch's metal housing that screws into the engine block).
OPERATION
The oil pressure switch is normally "Closed." The switch changes from a "Closed" circuit to an "Open" circuit, on increasing pressure of 7 psig. The
oil pressure switch changes from an "Open" circuit to a "Closed" circuit, on decreasing pressure, between 2 psig and 4 psig.
