Purpose
The passenger compartment temperature sensor detects the cabin temperature.
Function
The passenger compartment temperature sensor converts the detected temperature to an electric signal.
Construction
A thermistor-type passenger compartment temperature sensor has been adopted.
The passenger compartment temperature sensor is installed to the lower panel (driver’s side).
Construction/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.
