Saw it, thanks! So it's Bank 1 for this code if it comes back and if it's not solved by a reprogram...

If you have a smartphone, you can get a wireless OBDII dongle and the Torque app to monitor the O2 sensor pattern and see how the two banks compare. You may be able to see some differences. See the thread here and healthy O2 sensor signal in post #26

Also good to compare signal generated by old and new sensors once installed.

BTW this is the correct pre-cat one for your car - $102, not too bad

Just to follow up, thanks Ahsai, and the car made it to Indiana and back with no issues, so now it's been about 3000 miles since I cleared the code, no re-occurence since. If it comes back I will inquire about a re-flash and if that's cost prohibitive, replace that one 02 sensor. My least favorite thing to do is to spend money for someone to hook up a wire and press a button for something that should just be an free patch to correct an original fault.

Anytime and thanks for the update. Glad your car made the trip without any issues. Maybe just a fluke.
