Actually when I pulled the original sensor the 1164 H02S Circuit/Range Performance, 1166 H02S Heater System Electrical, and 1167 H02S Heater System codes were set. With the Bosch 15734 in there I'm only getting 1166 and 1167.

But guess what I just found out... Stupid racepages.com lists the Bosch 15734 as the universal replacement for my car, right next to a picture of the OEM unit when actually the 15733 is what I found on Bosch's own website. I'm not sure why I trusted racepages.com and I bought the sensor from the local Napa shop so I have no real recourse against racepages.com. I guess I'll give the 15733 a shot. Even after buying both the 15734 & 15733 it'll still be cheaper than OEM. If the 15733 doesnt' work then Bosch can refund my money.

Thanks for all the help.
