DTC Descriptor
DTC B0160: Outside Air Temperature Sensor Circuit LowDiagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
Ambient Air Temperature Sensor Signal Circuit | B0160 | B0161 | B0161 | -- |
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.
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. |

Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the ambient air temperature sensor.
- Ignition ON, verify OC is displayed on the DIC display.
- If all circuits test normal, test or replace the ambient air temperature sensor.
| ⇒ | If OC is not displayed, test the ambient air temperature sensor signal circuit for a short to ground. If the circuit tests normal, replace the instrument panel cluster (IPC). |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
