P0420 Error Code
Posted: Fri Apr 22, 2022 8:35 pm
Hey there,
Recently upgraded to a new exhaust which has replaced the catalytic converter it seems, as I am now pulling a P0420 Code: which is basically the secondary 02 sensor reading that the emissions aren’t being filtered correctly by the catalytic converter (which makes since since that whole piece has been replaced lol)
Still drives fine of course, so I am curious if it would be safe to simply turn off the secondary o2 sensor in Hondata and reflash the ecu.
Would this turn off the check engine emissions light, and would it be safe to do so?
Appreciate the help :)
