Differential Oil Temperature Sensor Inspection
WARNING: This page is about a different variant/trim than selected.
WARNING:
- Hot differential oil may cause severe burns. Do not perform maintenance while differential oil is hot.
- Disconnect the negative battery cable.
- Disconnect the differential oil temperature sensor connector and remove the differential oil temperature sensor.
- 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.
