Thread: Code P0418

Im getting the secondry injection code but im not exactly sure how to tackle this problem or where to check for a failure. Im also getting a p0420 code, i know my catalytic is messed up it rattles and im having that replaced soon. I wanted to get the remaining code fixed and have a clear dashboard.

I found this with a description all the way towards the bottom regarding p0418 but i dont know what it means.
