On the 2008 Kia Rondo,the P2422 is a fairly straight forward code pointing to a problem with the EVAP Canister Close Valve. The canister close valve is located under the vehicle, towards the rear. For best access, remove the spare tire. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. If the inspection checks ok, you can test the canister close valve with the use of an Ohms meter. The valve resistance should be between 15.5 and 18.5 ohms. If the inspections check ok and the valve is not within specs, replacing the canister close valve will solve the P2422.
