Sensor 2 Bank 2 is the left rear oxygen sensor. It problably is bad
and needs to be replaced before your next inspection. The rear oxygen
sensor just monitors what is coming out and isn’t as important as the
front oxygen sensor. The car will still run properly if you don’t
replace it but will not pass inspection, in most states, if you don’t
replace it. The part is inexpensive (about $30) but is hard to
replace without the proper tool. They make a special socket for
replacing oxygen sensors. You should be able to pick up the socket
for $15-$20. It has an opening for the attached wire. You could try
to remove the old one with an open ended wrench but you will probably
strip it. It’s a 22 mm or 7/8 inch

You don't need the tool, cut the wire off the old sensor which will now
allow a box 7/8 wrench to remove it. when installing it, just use the open
end 7/8 wrench.

Wouldn't hurt to soak the hell out of it with some Liquid Wrench,
WD-40, PB, or some other penetrating oil either. Those ****ers can be
tough to get out and any help you can get would be good.
