DIFFERENTIAL OIL TEMPERATURE SENSOR INSPECTION

id031800805600

Warning
•  Hot differential oil may cause severe burns. Do not perform maintenance while differential oil is hot.

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

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.
