Purpose
The ambient temperature sensor detects the ambient temperature.
Function
The ambient temperature sensor converts the detected temperature to an electric signal.
Construction
A thermistor-type ambient temperature sensor has been adopted.
The ambient temperature sensor is installed to the shroud panel on the back side of the front bumper.
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.
