its on the passenger side, near the firewall, over the fuel rail. You will need a 22mm open end wrench.

It will eventually throw a couple of codes, for lean o2, 2nd sensor, 2nd bank, and may also throw a low MAS reading code. These will trigger a check engine light.

I have a stubby 22mm spanner in the center console now, mine comes loose every month or so. When I get some time I'll drill the nut, and safety wire it on properly.
