Question (P0030) Heated oxygen sensor Bank 1 Sensor 1 location & part #

Hi all,

It's been a while since my last post.

I've been getting an EML lately either due to NOx sensor or oxygen sensor DTCs.
Where are they located? The car has 67k now, so I might as well replace both. The oxygen sensor 1 is on the exhaust manifold? Where exactly, which side? The NOx sensor is somewhere at the bottom?
The P0030-29 code came up today. I don't remember the code for NOx but the description was something similar to the oxygen sensor code.
Where can I find a part number for those two sensors?
I'd really appreciate your help, guys!

It looks like the cat needs to be removed to gain access...
Parts needed:

I took it to a local Jag indi and they had it done within an hour. They even washed my car, lol. All back to normal 👍🏼
It was the heating element, and when tested with a multimeter, no resistance value showed.

Scanning my car with an icarsoft 2 shows heated oxygen sensor temps ~1650 F, whereas catalytic converter only gets to several hundred degrees. Presumably a temperature much lower than this would indicate a problem with the heating element.
