your ecm (cars computer) is storing codes could be as simple as a loose gas cap could be a phantom code check gas cap disconnect battery (neg first) for 1 min start and drive light should be off at this point if it comes back on take it to auto zone for free diagnostics they can even save you the hassle of disconnecting battery they can read and reset ecm for free
Sounds like the Fuel Evap Purge Valve is stuck. When open, this valve channels gas vapors from your tank into your intake when you crank the engine. If it gets stuck open, then it could lead to additional air in your intake which upsets your fuel/air mix and leads to poor performance. Have the dealership check it out for you.
Also, make sure your gas cap is on tight. The code is thrown when the pressure in your gas tank is off which indicates a possible problem with the valve but a loose cap can also cause the code.
You need to read the code using a CAN code scanner and reset it. Most common fault is EVAP which indicates the cgas cap may have been loose. Look for rust around the top of the filler neck and clean it off with fine sandpaper then apply light grease and reinstall cap.
The cap might need a pressure check. Just because it stays on and tight doesn't mean it is functioning properly. It must meet EPA standards to function properly. Your cap is special part of your emission system and if it is not working properly you will need to replace it and have the light reset. If you owed a code reader it would tell you the same. Auto zone does do free code reading. The check engine light usually is not a big problem,but... I will leave it at that.
The computer that read the code for you can also reset it. If you don't have one, you can go to your local auto parts store and have them reset it for you. This is what your code means P0442 Evaporative Emission Control System Leak Detected (small leak). This is what Causes it and possible fixes:
CausesA code P0442 most likely means one or more of the following has happened:
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
A small leak/hole in a fuel vapor hose/tube
Other small leak in EVAP system
Faulty vent o-ring seal
Possible SolutionsWith a P0442, the most common repair is to:
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, or
Inspect the EVAP system for cuts/holes in tubes/hoses
