P0056 & P0121

[Mtl996tt]

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

1. Please do a search I have posted engine bank layouts many times.

2. Maybe or maybe it was just it's time to go. About 60,000 miles is where many O2 sensors start to degrade.

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 :)

Anyone know where I can get oxygen sensors for a better price than the Stealership? they're over 300$ each here in Canada.
