If you have P-0440-P0441-P0446, you can usually trace that condition to a loose fuel cap, or a fule cap that has a bad rubber o-ring, or rust build-up where the cap's o-ring seals against, at the filler neck opening. The cap is about 15 dollars, and the replacement filler neck is about one hundred sixty dollars

The EVAP cannister is part of the emissions system. Excess exhaust runs thru it-purge flow is when it is released. Check all the vacuum lines going to it. I don't you will find a parts listing for a purge flow valve or vent or solenoid. Your light will probably come on again shortly.
