See pic - is this the sensor in question? just want to verify before buying and swapping in a new OEM one.

Also, is this the replacement? BL3Z-9G444-A again, looking to verify so I'm not returning parts.
-Threw this code earlier in summer (truck runs fine), looking to replace the sensor (unless there is something else you suggest?) I use Stabil in the fuel as its not always driven a ton and thought that may have been the issue, but, that gas was run through this summer and new gas put in (no Stabil).

Thank you!

Maybe this will help. From a 2013 manual.

Have you checked for any vacuum leaks? I wouldn't just throw an o2 sensor at it without verifying that first. These trucks are starting to age and hoses will crack. I believe the hose that runs from the brake booster, air intake caused this code on my 5.0 but it's been almost 2 years and I don't remember the lean code it was setting.

If you want to replace the drivers rear o2 sensor that's the correct part number.
