Did you reset the codes after replacing the O2 sensor? It is possible sometimes that the values stored in the ECU for the earlier sensor may be giving the wrong readings. Try resetting the codes and see if it helps. Also, make sure that you replaced the part that was actually needed. If the OBD gives other codes, the problem might not be with the sensor.

Our 09 developed a loud rattle up toward the windshield. Turned out to be the plastic "cowling" that the wipers sit in which runs the length of the engine compartment. I think some servicing requires the cowl's removal so maybe it wasn't reinstalled correctly. Open the hood and along the seam where this cowling attaches to metal trim below (via snap in plastic links), squeeze a thin bit of weather stripping. I actually used a couple of plastic hose nozzle washers in the gap as a test and the rattle disappeared!Its a cheap and easy test in any case.
