V8 oxygen sensor question

[SC Joe]

I'm getting the CEL/VSC TRAC light. Checked the code and it is saying its an o2 sensor bank 2 sensor 1. Which side and sensor is that? Is it hard to get to?

Hmm..missed that. Thanks.

Maybe I'm reading pic wrong, but I see two bank 1 sensor 2, and no bank 2 sensor 1?

it's there. Squint, maybe? It is easy, you have 2 on each cat. 1 before, 1 behind. That should get ya to the right area.

Hmmm..I think i see where it should be..I think the pic is mis labeled.

This post clears it up (I think..if I can find the right p/n):
