I know an auto forum would be the best place for this question, but I don’t have a presence on any. I also know the collective forum knowledge will probably have an answer
Could a broken engine air intake hose cause the catalytic converter to throw a code?
07 Honda Odyssey. Was driving home tonight and the check engine light came on. Put on the OBD reader when I got home and got code P0420, which is the catalytic converter. The lowest hanging fruit for causes was a clogged air filter. I was pretty sure that was fine, but it’s also the easiest to check/fix. It was extremely clean, but I found that the air intake hose was brittle and cracked in several places. If that’s causing air problems and messing up the fuel/air mix, could it register as an issue way at the other end?
I’m going to replace it first thing tomorrow morning because it’s bad, but do I have any chance of actually fixing the code I have? If that does fix it, how long might it take for the code to clear on its own? Or, do I need to clear it myself and see if it trips again?
