So been getting a CEL code P2241; Air/Fuel Sensor bank 2 sensor 1. Finally ordered the part from Amazon for about $130.00 Denso 234-9051. Used a 7/8 inch open end wrench to remove/replace sensor. Hardest part was unplugging the old one from the connector. New sensor even came with anti-seize compound for the threads.
I've included pics of old sensor, and the box the new one came in with the part number.
Truck has just over 100K miles on it so I guess it's time to start replacing these sensors, I'll get around to the rest of them later.
Hope this helps someone in the future...
