I have a trouble code of P2270 What do you think the problem is on 2006 Ford Expedition

I have a 2006 Ford Expedition with 48ooo miles on it. I got this code about a month ago and the oil dip stick was not seated correctly. I pushed the dip stick all the way down and the code went away when I started the engine. Now the code has come back and the oil dip stick is seated properly. another suggestion i got was a bad O2 Sensor for Bank 1 Sensor 2. Where exactly is bank 1 sensor 2 located?
