I'm showing codes P0440, P0441, P0446 all somewhat related to this thread but I'm having some trouble. A good friend of mine says my issue is a bad purge control solinoid valve... hsould I also check these vaccumm lines like the beginning of this post?

These codes together mean there is a massive leak somewhere in the Evap system. Usually this is due to a broken or disconnected hose. As a first step, I would carefully inspect all hoses in the Evap system to make sure they haven't fallen off their connector or have broken from age.

Yeah it was a broken hose I found it and posted in another thread. The evap test hasn't run yet since I found and fixed the issue. I found this test only runs with 1/4-3/4 of a tank of fuel wish I knew that before I filled up. Will have to wait until I get back home in the next few weeks....

Thank you for sharing this diagnostic documentation. Is it from EG001R-99?
