    P0037 Code For The First O2 Sensor?

    Hi there!

    It has been a week since I did the weight loss and tunes.

    I keep getting a P0037 code for the first O2 sensor.

    I have returned the truck to stock each time and re-uploaded the tunes, but still having trouble.

    Tunes are through GDP.

    Does anyone have a solution?

    Thanks all!

    Contact your tuner and tell them what’s going on.

    Maybe they left something out that turns that portion off on the tuner or something.

    I wish I could help you out, bud.

    I do not know about GDPs tuning.

    A few fellas run with them on here; hopefully, they can chime in.

    I may add, did you have a tender hooked up while doing all this?
