Code U110E Description

The Ambient Temperature Sensor signal is a direct input to the Body Control Module (BCM). The BCM transmits the ambient temperature message to the Powertrain Control Module (PCM) over the Controlled Area Network (CAN) C bus. The Diagnostic Trouble Code (DTC) sets when the PCM doesn't receive the ambient temperature signal over the CAN C bus from the BCM. The circuit is continuously monitored. One Trip fault.
