Okay, so the real world picture shown is the downstream sensor, correct?

Maybe this will help.   This is the catalytic convertor (part) for my vehicle.   Is the hole in the highlighted upstream or downstream? 

I tried looking for it but can't find it.  I'm lost.  if you zoom the picture, you will see the oxygen sensor.   The photo is facing towards the engine. 

Hello.  I own a rebuilt 2018 Ford Edge SEL 2.0.  I'm getting a P0036 code (P0036 - HO2S Heater Control Circuit Bank 1 Sensor 2).   Where is the rear oxygen sensor located at?   See picture;  it this the correct one?

Is anybody else having this same problem?   Thank you for your help.
