These codes most likely mean the throttle body is dirty or has failed. Start by cleaning, take throttle cleaner from parts store, spray onto a rag, wipe out throttle bore and throttle plate. If that doesn't help then replace the throttle body but cleaning will usually solve the problem. Let me know if you have questions, thanks.
