Ambient Air Temperature Sensor
WARNING: This page is about a different car, the 2005 Lincoln Navigator and 2005 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The ambient air temperature sensor:
- is located in front of the condenser core.
- provides a resistance value to a reference voltage from the EATC module that is proportional to the outside ambient temperature. The resulting voltage is then returned to the EATC module where it is interpreted as a temperature reading.
