Oil Temperature Sensor/Switch: Testing and Inspection
1. Disconnect the engine wire harness connector from the oil temperature sensor.
2. Using an ohmmeter and a test thermometer, test the resistance versus the oil temperature relationship of the sensor between the two terminals of
the sensor as shown in the Oil Temperature Sensor Tests table.
3. If the sensor fails any of these tests, replace the faulty oil temperature sensor as required.
