Ambient Temperature Sensor / Switch HVAC: Description and Operation
Ambient Outside Air Temperature Sensor Description
The outside air temperature sensor is a temperature-sensitive resistor. The resistance of the outside air temperature sensor varies inversely with the
outside air temperature. As the outside air temperature increases, the resistance decreases. As the outside air temperature decreases, the resistance
increases.
The Electronic Climate Control (ECC) module monitors the outside temperature signal and uses this information in order to help determine command
signals.
NOTE: The sensor will not update when the vehicle is traveling less than 5 mph.
