As the resistance of the ambient air temperature sensor increases, the DIC senses a larger voltage drop across the sensor, indicating a lower temperature. As the resistance of the ambient air temperature sensor decreases, the DIC senses a smaller voltage drop across the sensor, indicating a higher temperature.
