It will clear by itself or you can clear it. If you wait the CEL might go out soon but the scanner will still show a code set, idk for how long or if it will at all. So I'd probably clear it.
If you clear it yourself all the emissions monitors will reset but not the fuel mapping, so mileage won't suffer.
