You can do a smoke test on the car to find the leak.

Take wd40 on a rag and clean where the gas cap seals, then take off the bottom vapor line from the purge valve (push in on the white locking clip and pull off the line) start the car and put you finger over the purge valve where the line was and see if you feel vacuum if you do the purge valve is leaking replace it. Rock auto has them

Has anyone had an issue with emission system leak PO442. Tried everything including smoke test. Any ideas?
I am getting a check engine light on indicating a PO442 Evaporative Emission System leak. Ford did a smoke test and could not find any leaks. I am able to turn off the light off using a check engine scanner but light comes back on after 100 miles approximately. Issue does not affect drivability. Does anyone have any experience with this problem?

Actually, it is probably a Franchised Ford Dealership, not Ford, which often has flunkies working there doing the easy stuff like smoke tests. They didn't do the test properly because the computer isn't telling you there is an EVAP leak for no reason. One thing we know for sure, they did not do their job or you would not still have an Evap leak. Did you pay them? Because I wouldn't have paid them a dime if they didn't fix it.
Resetting codes serves no purpose unless it's after you found and repaired the problem and want to expedite the CEL being turned off.
Yes, start reading on Post #1 of this thread.

Are you filling your tank even more AFTER the auto-shutoff on the gas pump clicks off? Try ending your fillup as soon as the handle pops off. Worked for me...
