In-Vehicle Temperature Sensor
WARNING: This page is about a different car, the 2015 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.
The in-vehicle temperature sensor contains a thermistor which measures the in-vehicle air temperature and sends that reading to the HVAC control module. The in-vehicle temperature sensor has an electric fan within the sensor that draws in-vehicle air across the thermistor.
