Kia Niro: Air Conditioning System / Ambient Temperature Sensor Description and operation

Description

Located at the front of the condenser, the ambient temperature sensor detects the ambient air temperature. It is a negative type thermistor; resistance will increase at lower temperature and decrease at higher temperature.

The sensor output is used to control discharged air temperature, calibrate the sensor, control temperature control door, control the blower motor level, control the mix mode and control the in-car humidity.

  

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

The compressor will operate manually.
