bank 2 Sensor 1 location?

[shamu2789]

Long time lurker, first time poster. This site is beyond helpful. I had a check engine light and pulled the codes. Turned out to be a bad oxygen sensor, bank 2 sensor 1. I was able to find the ones downstream, but had zero luck with the upstream one I need to change. Can anyone provide any input or pics as to how to get to it? It wasnt in the Diy posted on the site. For reference, this is an 07 M35X. Thanks all.

If you are under the car, there are two more up the front pipe about a foot or so from the lower O2 sensors. They are extremely hard to get to which is why I didn't bother with them when I made that DIY. IMO, and I do 99% of my own car work, I'd have left that for a shop if that ever went bad. I had ZERO tools that would allow me to get to it.

Oh wow. Yeah I have the tools to do most Diy projects as well, but you seem very capable so I will probably not be able to do it myself either. I was just trying to locate them to see if it was something I can tackle. Will take a look tomorrow. Why would Infiniti make them so difficult to access? Odd! Thanks for the reply man and the welcoming.

No idea but I had the same reaction of WTF? Very bad design IMO.
