Code U11E2 Description

This diagnostic determines the availability of the Atmospheric Pressure signal sent by the Powertrain Control Module (PCM) via a Controller Area Network (CAN) message. The diagnostic determines the availability by checking the received value is not equal to the Signal Not Available (SNA) default value. When the signal is not available, the PCM sends an SNA default value. If the Transmission Control Module (TCM) reads this value then the Diagnostic Trouble Code (DTC) U11E2 is set.
