Bank 1 is the right bank (firewall side). Bank 2 is the left bank (radiator side).

ok i am asking because i just replaced the o2 sensor (on bank 2) and i am still getting code 147. It's just annoying seeing that check engine light. I'm also getting a code 603 i believe. WTF.
Thank you for the info.

That is the aft-CAT sensor.

After CAT, easy fix on a lift, $50 + or -, from any of several suppliers in here.....

Just as an aside, as long as you'll do the after CAT sensor, why not do the remaining bank sensor so they're all 3 "new" and hopefully sending the same voltage signals.......O2 sensors do get "lazy".
