I replaced the bank 2 sensor 2 o2 sensor 'twice'. Then reset the code. Within ten miles the check engine light comes back on. The same code appears- p0160. I used an after market o2 sensor purchased from a reputable auto parts store. I am trying to get the check engine light to stay off in order to get the inspection passed. I am now told to buy a OEM Nissian o2 sensor and/or replace the ECM-( Engine Control Module). Could someone help me with the proper trouble shooting -diagnostics, before I start just replacing parts....

You need a charcoal canister and vent control valve.
You also need the EGR solenoid valve (I think it the brown one).
Valve is located in the valley of the V, towards the transmission side of engine.
Do these 1st and reset light. You may have other issues but you have to start here.

this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.

Working on one right now and hooked it up with a Snap On Solus scanner - It gives P0135 for 0/2 sensor bank 1 sensor 1. Check the 0/'2 sensor function and replace as necessary

If the car is pinging you will set a knock sensor code.'
This comes from bad gas and running lean., You really need this professionally inspected to rule out the basics. I have seen alot of nissans with the knock sensor code stored but the light is still off.
Fill up the tank with high octane chevron and some techron injector cleaner and clear the light. If it stays off for a couple days then go get it inspected. Even if the code is stored it will still pass as long as the light is still off and the monitors have run.

I think your sensors are pattern parts and the readings /resistances are not the same as the original parts ,try some bosch units is my first suggestion ,
