Good To Know

Q: What is the function of this water temperature sensor? A: It measures engine coolant temperature and sends that data to the ECU to adjust fuel injection and cooling fan operation.

Q: How can I verify if my sensor is faulty? A: Use a multimeter to check resistance at known temperatures; a defective sensor will show out-of-range readings or no continuity.

Slight variation in finish or dimensions may occur between production runs, and confirm compatibility before ordering.
