Dakota 2WD V6-3.9L VIN X (1997)
Oil Pressure Sensor: Description and Operation
Sends a signal from the oil pressure sending unit to the Powertrain Control Module (PCM) relating to engine oil pressure.
CIRCUIT OPERATION
The engine oil pressure sensor is a variable resistor. As engine oil pressure changes the resistance on circuit G60 changes. The G60 circuit
connects to cavity B23 of the Powertrain Control Module (PCM) connector.
Ground for the sensor is supplied on circuit K4. This circuit connects to cavity A4 of the PCM connector. This circuit is the ground circuit for
many of the components in the fuel/ignition system.
