I will give you a hint to find bank one you must find bank 1 bank one is the cylinder that is the closer to the main crank pulley in a V engine one cylinder is going to be farther forward than the rest you can tel by looking at the cylinder head or valve cover after you have found cylinder one the other side will be bank 2

Now about the HO2S ( that is code for heated oxygen sensor) s2 or sensor 2 is located after the main cat aka down stream. Now that you have found it you must find out what is wrong

Start with the DTC ( diagnostic troble code) that is telling you why you need to replace it keep in mind the ecu does not all ways know what is right
