2002 Dodge Ram Check engine codes P0422 and P0455

2002 Dodge Ram V8 Four Wheel Drive Automatic 122000 miles

Looking for a little help diagnosing problems that are causing codes P0442, P0420, and P0455. I know a new gas cap would be a cheap way to see if 455 gets taken care of but looking for a little direction in general.

Do you
have the same problem?
