Hey all, can someone please help with a oxygen sensor question?

I have a 2000 gs300 and it has a check engine light on with codes PO141 and PO161, bank 1 sensor 2 and bank 2 sensor 2 is I'm guessing "bad". Can anyone give me more info about this problem? And where are these things located at? Any help will be greatly appreciated!

THANKS A BUNCH!

Or anyone actually...

Thanks a bunch!

ANYTIME...

Hi Shawn, would you be so kind to help me on where bank 1 sensor 2 is on a 2000 gs300? Mine throw a PO161 (bank 2 sensor 2, which you provided us with a nice pic) and a PO141.

THANKS!!!
