Just wanted to post this because I saved a few hundred dollars doing the repair myself
I got the code read at Autozone
P1166
bank 2 sensor 2
bank 2 = left/driver
Sensor 2 = downstream
very easy the replace, the hardest part was disconnecting the old harness because I wasn't familiar with it.
the fault light is not going to go out right away but it will after a few days(give it about a week or so)
