Rottten muffler cause engine code

Is it possible that a hole in your muffler could cause an obd code of p0430? My muffler is starting to rot out at the end. I know its a far cry,but maybe...

I would consider it unlikely.

Re: Rottten muffler cause engine code

Are you sure you're talking muffler? P0430 is a catalytic converter code, and if one/both are bad, you'll get code(s). They are located in front of the muffler.....one for each cylinder bank. They are fairly small, maybe a foot long, or so. Your muffler (if stock) is gigantic and is located on the passenger side around the middle of the vehicle. As said, a bad muffler won't cause this code.
