DIFFERENTIAL OIL TEMPERATURE SENSOR INSPECTION
WARNING:
1. Disconnect the negative battery cable.
2. Disconnect the differential oil temperature sensor connector and remove the differential oil temperature
sensor.
3. Wrap the differential oil temperature sensor with plastic wrap and immerse it into a beaker filled with
water. Gradually raise the water temperature, and measure resistance between differential oil temperature
sensor terminals A and B.
If not as specified, inspect the harness for continuity. If there is normal continuity between the
terminals, replace the differential oil temperature sensor.
