Kia Carens: Air conditioning System / Ambient Temperature Sensor Description and operation
The ambient temperature sensor is located at the front of the condenser and
detects ambient air temperature. It is a negative type thermistor; resistance
will increase with lower temperature, and decrease with higher temperature.
The sensor output will be used for discharge temperature control, temperature
regulation door control, blower motor level control, mix mode control and in-car
humidity control.

If the ambient temperature is below 2.0°C (35.6°F), the A/C compressor
will stop.
The compressor will operate manually.
