Cabin Temperature Sensor / Switch: Testing and Inspection

IN-CAR AIR TEMPERATURE SENSOR




In-car air temperature sensor is located at crash pad. It is installed with humidity sensor.

CHECK RESISTANCE OF THE SENSOR:

It will detect interior temperature, which will be used for discharge temperature control, sensor fail-safe, temperature door control, blower motor level control, A/C auto control.






NOTE: Negative type thermistor, that resistance will rise with lower temperature, and reduce with higher temperature.
