PCM Diagnostics & Tuning - ses light

My ses light came on so I went to autozone and had them scan it. The guy told me that it was the number 1 o2 sensor in bank 2. Which one is that? Also I have never had my computer tuned, could this be the reason that the o2 fouled out?

Bank 2 sensor 1 is the passenger front O2 sensor.

Bank 1 is drivers side, Bank 2 is passenger side. Sensor 1 is before the cat, Sensor 2 is behind the cat. Got the actual code you could post? They do read them free which is great, but I'd be sure they told you right before replacing it.
