A 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 Solutions With 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
