Thats right. Bank 2 is right in front of you when you open your hood and look down. The 1st 3 cylinders you see are 4,5&6 and that is bank 2. Toward the bottom of the cylinders (the exhaust manifold) there will be a greenish / blue plug with a couple of wires coming out of it. That is the O2 sensor 1st position. if you follow that pipe down under the engine it runs to one of your catalytic converters where you would find another O2 sensor for 2nd position bank 2.
