B0160

DTC B0160

CIRCUIT 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.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B0160 Outside Air Temperature Sensor Circuit Low

CONDITIONS FOR RUNNING THE DTC
The DIC must be fully operational within a continuous voltage supply of 9-16 volts.

CONDITIONS FOR SETTING THE DTC
The sensed temperature must be greater than 60°C (140°F) for more than 2 seconds.

ACTION TAKEN WHEN THE DTC SETS
SC is displayed by the DIC in the compass/temperature mode when the condition is present.

CONDITIONS FOR CLEARING THE DTC
- DTC B0160 status changes from current to history when the condition is no longer present.
- History DTC B0160 will clear after 100 consecutive fault free ignition cycles.
- The DTC can be cleared with a scan tool.

TEST DESCRIPTION
