I had that code also for a long time. Car drove fine for a while and everytime I went to clear it, the code came back time and time again. It is a faulty sensor for sure, but when it finally takes a crap you will know for sure as the car will misfire and won't allow you to apply half or full full throttle. You can cruise with it normal but as soon as you got WoT it will sputter and misfire. I would tell them to change it out.
