Re: catalytic converter? P0240 Is the error P0240, or P0420? Catalyst system efficiency below threshold is P0420 although it seems that dyslexia on the internet is very common and they get flipped.
I'd visually inspect things to make sure that there isn't any damage to the O2 wiring harness, make sure the plug(s) are tight, etc as well as make sure there aren't any exhaust leaks, reset the code, and go from there.
That's funny, because the first reply I typed "P0420" then realized it didn't match his post and changed it. Guess my subliminal memory should have been obeyed.
