I would NEVER think a code that says "nox sensor" means unequivocally that the nox sensor is bad. Never. Good guess perhaps, but not the only thing that can trip codes.

You're absolutely right. I've run out of ideas so before it gets too crazy, I'm going to have a friend's indy shop take a look at it for me this afternoon.
Also, the code (3 codes) are all referring to the name nox sensor.
they are:
46B4: NOX Sensor before denox cat plausability nox.
4BB3: Nox sensor before denox cat- plausibility nox
4b6a: Nox sensor before denox cat - Plausibility
to me, I'm reading it as the nox sensor before the cat has died.
