Oil Pressure Gauge: Description and Operation
CIRCUIT 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.
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.
