Dealership should be able to confirm.
For Bicohon (and anyone else),
The Rear OEM O2 Sensor part number is: 89465-30730
Covers both Left & Right sides attached to mid-pipe
You can buy them from Desno directly

Or slap the OEM one on for them and make them happy..
It's not uncommon for the O2 sensor to fail as seen with Bichon's issue.
You just have to know which one failed.... Sometimes those front exhaust gaskets fail too..

For those following my saga, I figured I'd post a follow-up. Two days after my check engine light came on with the P0420 (and before replacing the sensor or phoning my dealership), it went off by itself. I figured it would be back, but after six days of driving that included long trips, short trips and my usual commute, it is still off.
One of my acquaintances mentioned that he often gets CEL for a few days around this time of year when the stations change to winter blend gas. (he didn't check his car, not a Lexus, to see what code was set) An interesting thought, though I am skeptical that it is related to my problem.
At the moment, I'm tempted to do nothing but wait to see if the problem returns.
