You should be able to clear the code with an OBD II scanner, it doesn't go away by itself even when the problem is corrected. At least, as far as I know but I may be wrong. If you don't have an OBD scanner, any garage should be able to clear but they may charge for that. It only takes a minute.

Or you can just disconnect the battery dor 15 minutes or so, this will reset teh ECU and all the errors.
