DME: Trimming, oxygen sensor before cat., Bank 2

[Fifty150hs]

After searching the forum and having found numerous threads about it, I'm totally confused. I hope someone can help me with this. I have a 2006 3.0 that just started throwing the code above. I've cleared it a couple times and it comes back. So I opened up the OBDII and got the live data. The live data is below. I hope someone can tell me what I'm seeing.
