So my car thru a code 2 days after buying it, turns out it's p0430 cat system bank 2, which side of thr motor would that be?

 

Drivers side

 

thanks man, funny thing is that cat converter was just replaced a few days ago.. wonder why its throwing a code.. hmmm 🤔

 

Why was the original cat replaced (same code)? regardless, if the work was done by a shop, you might want to take it back. If you or a friend did the work, then you might want to dive under there and make sure everything is tight and the O2 sensor wires are not pinched or damaged. G-Trivia: the driver's side is the difficult one to work on, not saying the other side is easy, but...

 

It was done professionally at the shop I work at. The guy that did it is going to take a look at it soon. As for why it was replaced.. I'm not sure, it came thru my shop for an inspection before it went to the dealer, where I bought it. My boss said he believes there was a rattle noise coming from the cat, so they replaced it

 

Did you use some aftermarket cat as a replacement?

 

well it looks like the factory one does, but I'm sure it is aftermarket

 

I bought a aftermarket one too and I would have the light come on randomly so I would just reset it until the next time. Assuming everything is okay with the install I think it's just a roll of the dice when dealing with aftermarket cats.

 

Update to this... it most definitely is an aftermarket cat, and as of now I just keep clearing the code. Pops up every now and again.
