Evp valve

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 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
