Purpose
The evaporator temperature sensor detects the airflow temperature passing through the evaporator.
Function
The evaporator temperature sensor converts the detected temperature to an electric signal.
Construction
A thermistor-type evaporator temperature sensor has been adopted.
A fin-thermo-type sensor has been adopted to the sensor area of the evaporator temperature sensor which inserts between the evaporator fins.
The evaporator temperature sensor is installed to the A/C unit.
Operation
The thermistor changes the resistance according to the surrounding temperature.
The resistance decreases if the temperature increases, and conversely increases if the temperature decreases as shown in the figure.

Fail-safe
Function not equipped.
