Does anyone have a link to search error codes on an 01 Gt? I plugged it in to a scanner and it showed P420 Catalyst system below threshold bank 1. Any suggestions? I am thinking maybe an 02 sensor. The car has pretty much been stored for over a year for my son who is returning next week from the military overseas. Any opinions would be appreciated. Thanks

Error code

Thanks for the link it says. "P0420 Catalyst System Efficiency below Limit - Bank No 1." But what does that mean?

That is a common one, try a search of 4.6 tech and I am sure you will find the answer.

P0420 is usually caused by the cat (bank 1 in this case) not doing is job anymore. It's a good reason to buy an O/R mid pipe with MIL eliminators . On the our cars the cats all come together as part of the mid pipe so you'd have to buy another stock mid pipe which is very $$$$ new.

A diagnostic test by a GOOD tech would be able to confirm 100% that the cat is the problem.
