Hi there:
P0442 - Evaporative Emission Control System Leak Detected (small leak)
This\012 indicates a fuel vapor leak in the EVAP control system. It means a very\012 small leak has been detected. In fact, the leak can be from a hole as \012small as 0.04" in diameter. The (EVAP) emission control system prevents \012the escape of fuel vapors from a vehicle's fuel system.

Fuel \012vapors are routed by hoses to a charcoal canister for storage. Later, \012when the engine is running a purge control valve opens allowing intake \012vacuum to siphon the fuel vapors into the engine.

You likely won't notice any drivability problems.

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

Hope this helps; also keep in mind that your feedback is important\012 and I`ll appreciate your time and consideration if you leave some \012testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
