    P0125 Disable or fix???

    Hey guys im fighting a P0125 code and looking for suggestions on how to remedy this, The car is on SD with both front and rear O2 sensors off with temp set to 300F, i'm assuming this is why im setting this code, should i just disable the dtc in the tune or do i have another option?? Just dont like disabling dtc if i dont have to TIA

    Insufficient Coolant Temp code? I'm not on computer to look. If so I always disable that one. When you set the enable temp to a high number it will set that code thinking something is wrong keeping it from ever warming up enough to go closed loop.

    It's possible disabling Upstream O2s would keep it in open loop and not cause code but never tried that way.
