Oil Pressure Warning Lamp/Indicator: Description and Operation
Circuit Operation
CIRCUIT 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 from fuse 17 in the fuse block connects to the instrument cluster and supplies battery voltage to the oil pressure lamp. When the switch
in the sensor closes, voltage flows through the oil pressure warning lamp through the switch to ground.
