CEL P0420
CEL P0420
Just installed a RV6 downpipe , a CAI and the uploaded the ktune mods tune . I keep getting this p 0420 code. I have adjusted the sensor elbow almost to the point that it is almost out { per RV6 }., I am lost on what to do now to fix it. Anyone have an idea?
Re: CEL P0420
We can't direct you on disabling emissions equipment. For testing purposes there are off-road use only disable options available in the software.

I’m not looking for that. I’m looking for a fix not a cut off...
Re: CEL P0420
In that case contact the manufacturer of the part that's causing the code.
