Hello, after the great gas filler neck recall debacle and almost $4500 in repairs to my fuel system, I’m now getting codes P0164 for the O2 sensor.

I ordered one and it was a 5 pin whereas mine look to be 4 pin. Can anyone tell me exactly where they are located? I do not have any after the big cat and I found 2 just after drivers door on the two exhaust pipes. I have a 2016 LR4 HSE 3.0 SC. I have scoured the web for diagrams and now. My code translates to bank 2 sensor 3 which should be driver side rear?

Any and all help is appreciated

thank you
CM
