DTC Descriptor
DTC B0160
- Outside Air Temperature Sensor Circuit Low

Diagnostic Fault Information





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.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the ambient air temperature sensor.
2. Ignition ON, verify OC is displayed on the DIC display.

• If OC is not displayed, test the ambient air temperature sensor signal circuit terminal A for a short to ground. If the circuit tests normal, replace the instrument panel cluster (IPC).

3. If all circuits test normal, test or replace the ambient air temperature sensor.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
