Re: P0420 Code
What vehicle are you referring to?
Re: P0420 Code
I'm having the same issue. 2018 2.0 6mt stage 2 with flexfuel. Just installed the catted street pipe from PRL and after 100 miles the p0420 code appeared. I cannot even clear it with the hondata mobile app. Any ideas? Thanks!
Re: P0420 Code
Emissions error codes cannot be disabled in the CARB FlashPro.
I'm not sure if the downpipe you are using is emissions legal, but it should not trigger an error code if it is.

Interesting, yes this is a high flow cat I thought it was emissions legal since it has a cat...but I don't know. It's from PRL.
