SOURCE: error codes p0442 & P0455
Those are both Evaporative Emission Control System related.
442 is a small leak has been detected.
455 is a bigger leak has been detected.
Check all your connections, (electrical & vacuum lines) as well as check for any cracked, loose vacuum hoses in the system, as well as clean "O" ring on your gas cap well and threads in filler pipe & make sure gas cap is tight. Do the gas cap first & see if codes dissappear, but it may take a new gas cap. These codes commonly appear shortly after getting gas, due to cap not back on tight.

P0430 Catalyst System Efficiency Below Threshold (Bank 2)
P0441 Evaporative Emission Control System Incorrect Purge Flow
with p0441 did you replace the gas cap on all the way? that will cause this code every time. and or have you ever replaced the gas cap?

A lot of times, an evap code can be set by running the vehicle with the gas cap off. Also, if the gas cap is faulty, it can set the code as well. You may want to check the cap first (at least it's fairly inexpensive) and make sure it's sealing correctly. You can have the code reset at Auto Zone or Advance Auto Parts. If the code comes back, you may want to consider changing the cap, but make sure you replace it with the correct one. Not all gas caps will do the trick, resulting in the code just coming back. I would recommend purchasing it from the dealer.
I hope this helps to get you started! :)
