If you do some searching, you'll discover that there is actually a flash update to address this. I think they just increase the tolerance of the reading of the sensor. Same applies to the P0191. When I got this code last time, the P0191 was there too. Anyway, I did nothing and the check engine light went off in a couple of days. I've had it happen twice now. The first time I took it to the dealer. They reset it and told me nothing was wrong. The second time, I found it on this forum and basically was told to ignore it and let it go away on its own - which it did. If you really have a problem with a sensor, I would expect it to be covered under the 7/70 warranty. But, there may be a deductible. I'd just ignore it for now and see if it becomes chronic.
