    Default Duramax LML Ambient Temp sensor not reading properly

    I had my 2015 Silverado Quad Cab Diesel with the LML motor lifted and EFI-Live installed and now the temperature reading on the radio is reading -40 degrees. The ambient temp sensor was replaced. The ambient air senor is reading correctly on the truck but not communicating it to the radio correctly. The A/C and things work problerly. The radio and bcm are reading properly and even tried reprogramming them both and still the same reading of -40 degrees. I am not sure if it is partly controlled by the dpf filter. Has anyone come across this?

    2015.5? Get a hold of your tuner. It can be a few things, but is related to how the deletes were done.

    It was one of the first ones. I ordered it and picked it up in November 2015. The company the did the work has done other 2015's and they have not seen this.

    From my experience, the Temp not displaying correctly on the dash is because the ECM isnt transmitting the temperature along the CAN Bus. Probably because the message was turned off.
