If you pull off the hose from the evap canister and then pull off the other end up by the purge and blow air through it, see if you get a bunch of vlack pellets

That is the complete diagnostic chapter for that code. Most of the time when I see that code, the evap canister has failed and filled the line from the canister to the purge control valve with the charcoal pellets.

Since you checked that line, and it's clear. Then you need to go through these steps to isolate your issue.
