Engine Oil Pressure Sensor/Switch - Circuit Check

Oil Pressure Switch

Circuit check

1. Turn the starter switch to ON.
2. Disconnect the oil pressure switch connector, and confirm that the oil pressure-warning lamp lights when the connector on the harness side is grounded. If the warning lamp does not light up, check the circuit between the meter and the oil pressure switch, and repair the disconnected locations.
