Bank 2, Sensor 1 replacement?

[x37mfini]

Hi everyone long time lurker but first time posting. I have a 2011 Infiniti M37x with these codes, p1168, P0302, P0150, and P0153. I've ordered some new spark plugs and I'm hoping that with replacing Bank 2 sensor 1 (upstream) could get rid of these codes. However, I don’t know what sensor I should use. Can anyone lead me in the right way? I see 2 on Rock Auto but they have different connectors. These are the two I’m talking about: Denso 2349135 or Denso 2349036. Which should I choose? If links help I can provide those too. Any help is greatly appreciated.

The Nissan/Infiniti part number is 22693-1MR0A (original) or 22693-3RC0A (supersession). Use those numbers in the Part Number Search tab on Rock. Never search for electronics stuff by MMY, it's a fool's errand. Getting the right N/I part number is easy by plugging your VIN into https://www.infinitipartsdeal.com.

Hi again! so i’ve replaced that upstream sensor and now I need to replace the downstream sensor. what’s the part number? Is it possibly the Rear heated oxygen sensor? sorry for the questions!

Yes, "downstream" refers to the rear HO2S. The database shows the same sensor on both sides on all '11's, p/n 226A0-ET000, no supersessions.
