    Sorry for the late reply here. That code is for Ambient Air Temperature Sensor. It is either the sensor, or the connector/harness. Take a look for a sensor near the mirror, or somewhere that exposed that it would read the outside temperature.

    You can look at www.TruckFaultCodes.com (or the mobile apps) to find this as well.
