Code B0160 Cadillac Description

The Driver Information Center (DIC) applies 5 volts to the ambient air temperature sensor. The ambient air temperature sensor is a thermistor which varies in resistance as the temperature changes. 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.
