Oil Pressure Warning Lamp/Indicator: Description and Operation
The case grounded oil pressure sensor is a variable resistor and switch. The variable resistor in the sensor connects to the oil pressure gauge on circuit
G60. The switch in the sensor connects to the oil pressure warning lamp on circuit G6.
Circuit G5 connects to the instrument cluster and supplies battery voltage to oil pressure lamp. When the switch in the sensor closes, voltage flows
through the oil pressure warning lamp through the switch to ground.
