  1. My car only has 25,000miles. Your right Loren, im sorry, I did lots of searbing regarding the P0161 & P0056 codes, but did not think to do a search on the banks. Thanks for the suggestion :)
  2. Hey guys, Heres the story. Recently I was getting the P0420 & P0430 CEL due to my High flow cats, so I decided to get O2 extentions and install them. Now that Ive installed the Oxygen sensor extentions Im getting P0056 & P0161 Error codes. I looked up the codes and they both seem to be related to post cat Sensor on Bank 2. I have 2 questions; 1-Which is bank 2? 2-Did I break that sensor? SHould I order a new one? *EDIT*: Sorry guys in the tittle I stated error code P0121, but the actual error code is P0161. It was a Type O, sorry :) THanks Nick
