The local AutoZone plugged their scanner and pulled trouble code P0442
on my 2002 Sonata GLS. The result said it was "EVAP small leak /
no-flow condition:: 1. Defective or loose gas cap, 2. EVAP canister or
hose cracked / not connected, 3. Purge or vent solenoid defective, 4.
Vacuum leak at engine. The light just came on yesterday afternoon at
90800 miles and is the first time I ever had a check engine light come
on. I checked the gas cap and turned it until it clicked but the light
is still on. Any clue about this one?

I had the same problem/code and, after resetting, the light came on
again within a couple of miles. Ended up replacing the gas cap and
light has remained off and no codes are showing. It will take several
cycles for the light to clear by itself but Autozone should be able to
reset the light for you if you don't have access to a code reader. On
my car, a GM, disconnecting the battery did not clear the code and lamp
remained lit until I canceled out with my scan reader.
