Oil Pressure Sensor

The engine control module (ECM) calculates the value from the oil pressure switch signal.

ON = the oil pressure switch circuit is closed, signal to the driver information module (DIM) via CAN for lit oil pressure warning lamp.

OFF = the oil pressure switch circuit is open, signal to the driver information module (DIM) via CAN for oil pressure warning lamp not lit.
