The P0402 code is for the EGR system which is flowing too much gases and the P0422 code is for the catalytic converter is not working as it should for the bank one but it might be triggered because of the first code which should be fixed first. Lets remove the EGR valve so we can check it, this video will show you how, and I have included instructions and the location of the EGR valve in the diagrams below.
