Which Oxygen Sensor is this? - Honda Pilot

Good Afternoon Folks!
My '05 EX has presented me with a weekend project. I get this code from the OBDII - P2237 Rear Air/Fuel Ratio (A/F) Sensor (Bank 1, Sensor 1) IP Line High Voltage. My take on this is that it is the OS on the rear cylinder bank exhaust manifold. The darn things are too expensive to just start replacing them until the light goes out. What do ya'll think?

Yes bank one sensor one is in the manifold by the firewall. Have you tried resetting it and waiting to see if it comes back?

Not yet, but that's first on the agenda this morning after coffee!
Thanks a bunch,
