You mean the ECU reflash recall? I had the same one on mine and they did not replace the sensor; they just did the necessary reprogramming. I never had a CEL before, and I haven't had one in the 1000 miles since I had it done. But random CELS was why they issued the recall. Just bring it in and have them do it. If it still throws CELs, just bring it back to have it checked out.
