Question
How to diagnose faulty transmission fluid temperature sensor?
Answer
Compare sensor readings with ambient temperature and test sensor resistance.
Explain
A faulty temperature sensor causes incorrect shift points. CHEPQ tools measure sensor resistance (varies with temperature) and compare to ambient readings—replacing the sensor restores proper transmission operation.
