Oil Pressure Gauge: Description and Operation
CIRCUIT OPERATION
The case grounded oil pressure sensor is a variable resistor that connects to circuits G6O 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 and supplies battery voltage to oil pressure gauge. The gauge uses two coils. One coil receives fixed
current, circuit G60 connects the other coil to the pressure sensor. As oil pressure changes, the variable resistor in the sensor changes the current
flow through the second coil in the gauge. A change in current flow alters the position of the gauge pointer.
