Can anyone tell me the O2 sensor locations on an 08' Xterra?

Long story short, my mother recently purchased an 08' Xterra. She had codes come up regarding emissions, more specifically the O2 sensor. Nissan dealer is claiming it is located inside the driver side rear bumper. I find this very hard to believe, but having not looked myself I cannot confirm or deny that claim. She lives too far away for me to travel to/from in a day to take a look, so I was hoping someone could help me out with some info on this.

Thanks in advance.

joey, pm me the codes shes getting, I have lots of freinds at the nissan dealership, they might be able to help out too.

I have mitchell on demand at home, but I think it only goes up to 07......and no, o2 sensors will not be behind the drivers rear bumper.....

do you know if any other year (05-08??) would be the same?

Also, which sensor are you needing to locate exactly. B1S1, B1S2, B2S1, B2S2?

From what little info I found, looks like both banks, the first sensor is a wideband a/f sensor, and both downstreams are standard o2's.
