2006 rav4 oxygen sensor locations

A recently triggered CEL , indicated a faulty Bank 1, Sensor 2 Oxygen Sensor. What do the references Bank 1 & Bank 2 mean with respect to location? I realize that Sensor 1 is Upstream & Sensor 2 is Downstream. I haven't been able to locate a diagram to help pinpoint the exact locations. Can anyone provide the exact location of the Bank 1, Sensor 2 Oxygen Sensor?

bank 1 typically means the bank with number 1 cylinder on it, number 1 cylinder is usually the first cylinder at the front of the engine on v engines one cylinder head sets a little further forward than the other that cylinder head should be number 1 for most manufacturers.
you can also look up engine firing order diagram for your engine size to determine where cylinder 1 is.
