GAH! Stupid P2241!
Oxygen Sensor Pumping Current Circuit Low, Bank 2, Sensor 1, Code P2241 is back AGAIN. Apparently I got a bad sensor out of the box? I am going to try a Denso sensor. I cheaped out and went with a walker (from Amazon) for $30. Guess I wont do that again. If (when) the front bank fails, I'll replace that one with a denso too. So far the only code to return has been the 2241. Whats weird is it comes and goes. If I let the car sit a few days (like over the weekend, the CEL will go away until the car warms up, then typically by the time I get to the freeway (about 5 minutes or so), it comes back again.

Two Thoughts:
1) before replacing a part that has multiple others on the car (like a spark plug, coil, etc), swap it with another one and see if the fault/fault code follows. If not, look beyond the part for the cause.
2) Beyond that, 02 sensors are easy to test on the bench with a voltmeter and a torch. You can google the values/procedure; it is quite simple.

I think I got it. The Denso Air/Fuel Sensor seems to have fixed it. I changed the sensor, cleared the code, and drove it 60 miles. The CEL has not returned, so I am calling it good.
