    Default ambient temp. sensor stuck at 32 degrees (freezing) after tune

    On a 2016 Silverado, after reading codes, reading tune, modifying and flashing I now get a warning about ice and 32 degrees readout on IPC

    Is this normal and how to reset?

    Think I may have found the answer:

    I had that happen once with the e92 reprogram. I disconnected the battery and crossed the power and ground to completely drain all the modules. Then everything re-synced and all was fine. Hope yours is that simple.

    Thank you and that's worth a try to see if it can speed things up albeit there may be minor other consequences to that procedure (radio stations, time, fuel trims, codes) but maybe not.
