Mine gets similar codes all the time, and usually it's the O2 sensors faulting. The dealer will replace them under warranty in most cases, unless they are shady and try to blame your HFC. The light will go off and stay off for a while, but has always come on again later on as temperatures vary. I've had the secondary and primary sensors changed at least 4 or 5 times already. I've learned to ignore it when it comes on now, and it goes away after a 1000 miles or so. I usually get the CEL when it's hot as hell outside. I think it's the F.I. HFC's or my uprev tune causing it.
