What is your question?
Will not pass emissions test because of these codes. Will cleaning the EGR ports fix the problem or at worst case replacing the EGR Valve fix it. Is this the only thing it could be?

Cleaning, maybe? If old enough will likely need egr valve. Can also clean port area while apart before install new. May not have egr problem, could be external problems. Elec connections, etc. Components that work with egr?
