Evaporator Temperature Sensor: Description
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The evaporator temperature sensor is a thermistor with a sensing probe that is inserted between the fins of the A/C evaporator at its coldest point. The evaporator temperature sensor prevents condensate water on the A/C evaporator from freezing and obstructing A/C system air flow. The sensor probe is filled with a special silicone-based thermal grease. Two terminals within a molded plastic connector receptacle on the sensor connect it to the vehicle electrical system through a wire lead and connector of the HVAC wire harness. See Fig 1.
