Flip open your gas tank cover, unscrew your gas cap, then screw it back on and get a few clicks past the resistance. CLICK CLICK CLICK CLICK.
Disconnect the black cable from your battery and wait a few minutes.
Reconnect cable and start up the car. Hopefully the code is cleared and will not come back which means it was the gas cap.
If the p0442 comes back, it may be a dirty EGR.
GOOD LUCK!!! I hope it's just the gas cap for you. Sometimes if I get full serve gas, I hope out of the car and turn that gas cap so it makes noise if I don't hear the attendant doing it.
