A code never identifies a bad part, just a failed system. The fact it came on so soon says you have an electrical issue with the wiring.
Get a shop to check it for you so you dont throw any useless parts at it.

Bank 2 is the right bank, hope you have not mistakenly replaced the wrong sensor. The other thing is non OEM sensors sometimes do not work.
