    Given those two codes together, I'm going to guess it's the EVAP cannister purge valve. This is a common problem on your type of car and a sticking or leaking valve will definitely throw both those codes.

    I can't say it's the right answer, but it's an educated guess, so unless you want to take it to a qualified technician, this is the best we can do for you from this distance. Good luck with it.

    I have replaced the purge valve, If i have made the proper repairs Will the codes clear right away or do you have to drive it for a certain amount of miles?
