Oil Pressure Gauge: Description and Operation
The case grounded oil pressure sensor is a variable resistor that connects to circuits G60 and G6. Circuit G60 connects to the oil pressure gauge. Circuit
G6 connects to the oil pressure warning lamp.
Circuit F14 connects to the instrument cluster at the left connector and supplies battery voltage to oil pressure gauge. The gauge uses two coils. Current
passing through the coils creates a magnetic field. Position of the gauge needle is controlled by the amount of current passing through the coils to ground
at the sensor.
