That is a good link to read up about your fault code. But it's incomplete. If you attempt to over fill your gas tank the charcoal canister can get saturated with too much liquid gasoline and take a long time to purge. Stop when the nozzle clicks, don't add any more gas to 'round it up' to the next dollar. the evap charcoal is supposed to collect fumes to prevent them from releasing in to the air, then get sucked out, purged by normal vacuum to intake but if gas runs down the hose it can collect in a low point in the hose to the canister also.
