O2 Bank 2 Sensor 2 is on the driver's side post-cat.

my cat is on the pasenger side and there is no sensor after the cat going into the tailpipe it goes up over the axel and to the muffler

Our 2001 Pathfinders have two catalytic converters.

[oldfordman68]

not this one you can see where they come off the manafolds the left side crosses over into one catalytic converter on the right then stays on right side to muffler

You are mistaking a resonator for a catalytic converter. See both #11 Three Way Catalyst:



Also see #3, which is the O2 sensor you are looking for.
