Cabin Temperature Sensor / Switch: Testing and Inspection

IN CAR SENSOR




1. In-car air temperature sensor is located at crush pad.

Check Resistance Of The Sensor:

2. The sensor contains a thermistor which measures the temperature of the inside. It perceives the inside temperature, changes the resistance value, and enters the corresponding voltage into the automatic temperature control module.

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