Check engine light comes on after I fill up my gas tank ...· Hi. I have a 2013 Honda Accord Sport with 115k miles. Since September, my check engine light comes on 5 minutes after I fill up or when the tank gets down to 1/4. It goes off in a couple of days and stays off until I fill up again. My fuel mileage has also gotten terrible. I got it tested and the code P0420 came up. The guy at Auto Zone (seemingly inexperienced) told me it was the catalytic ...
