4WD/AWD Rear Differential Unit Temperature Sensor

Where it lives

For C0094, the part to look at first is the sensor named here.

Check these first

• The differential temperature sensor fouled by oil
• A failed sensing element inside the sensor
• A drifting or erratic temperature signal
• A sensor that does not match the differential unit
• A loose or corroded sensor connector

What to do next

1. Compare the sensor reading to the fluid temperature
2. Inspect the sensor and connector for leaks or damage
3. Check the rear differential fluid level
4. Replace the sensor if the signal stays wrong
5. Clear the code and retest
