In-Vehicle Temperature and Humidity Sensor - Hybrid
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The in-vehicle temperature and humidity sensor contains 2 thermistors, which separately measure the in-vehicle air temperature and humidity and send those readings to the HVAC module. The in-vehicle temperature sensor has an integral electric fan within the sensor that draws in-vehicle air across the thermistors.
The in-vehicle temperature and humidity sensor is mounted to the instrument panel to the right of the steering column.
