Description

The ambient temperature sensor is located in front of the condenser and measures the outside air temperature. It is a negative temperature coefficient (NTC) thermistor; its resistance increases at low temperatures and decreases at high temperatures. The sensor output is used for discharge air temperature control, door temperature control, cooling fan speed control, blend mode control and in-vehicle humidity control.
