Confirmed, yes it is, and the connector for it is to the left and forward of the coil pack for the #1 cylinder. When looking at the engine it is the far back left cylinder

ok so i tested out the sensor and it tests out the same as the other sensor which is two months old, can the check engine light be coming on for another reason that isn't due to that sensor being bad?

How are you testing it?
No, that's a cat efficiency code that could be caused by a upstream OR downstream o2 sensor. Chances are very likely that if you have a bank 1 sensor 1 code that o2 is crap.

yea i was testing it wrong, i followed this instruction sheet but after some research figured out that you can't test the O2 sensor without it being connected, i'm going to test it the right way now
sorry for bumping a month old thread btw.
