Question
How to test faulty automotive differential oil temperature sensor?
Answer
Monitor sensor resistance and compare with oil temperature.
Explain
A faulty differential oil temperature sensor causes incorrect temperature readings. CHEPQ tools measure sensor resistance (varies with temperature) and compare to actual oil temperature—replacing the sensor ensures proper differential operation.
