Hi guys,

Its my first post so please bear with me here and feel free to ask questions. I have a 2007 TL-S M/T with two engine codes: P2272 and P0420. I have had the p0420 code for quite a while but I tested the associated sensor (I cant seem to remember which one it was a long time ago) and all seemed okay with it, so to avoid buying a new cat I decided to ignore it. Now however, I have gotten a P2272 code as well and I have decided I want to clear both codes. Are they somehow related and only need 1 part to fix both codes? I can't seem to find a clear answer on what sensors to replace so I figured to make a post of my own and get some more advice. I understand that these codes could be completely uncorrelated but any advice to clear this up will be greatly appreciated. (If it helps the car smelled a little rich before the p2272 and now it's smelling a little more lean)

Thanks guys,

Zinoviy

You might be able to get away with just replacing the o2 sensor (bank 2 sensor 2) make sure you get NTK/OEM

This should be b2s2 if i'm not mistaken
