The oil pressure switch is located in a threaded port in the bank 2 cylinder head. The sensor is connected directly to the Body Control Module/Gateway Module (BCM/GWM) assembly.

The sensor is not connected to the Powertrain Control module (PCM) but is supplied with a reference voltage from the BCM/GWM. The sensor ground is through the sensor body and the engine. When the oil pressure falls to below a predetermined threshold, the switch contacts close, completing a circuit from the BCM/GWM. This circuit is sensed by the BCM/GWM which displays and appropriate warning message and warning lamp to alert the driver.
