This code means there is a small leak in evap system, usually means the fuel cap or the fuel filler tube is leaking. To test the vent solenoid you will need a vacuum pump. With power/ground applied to solenoid it should hold vacuum then when disconnecting power/ground it should allow vacuum to pass through it. Best way to diagnose this problem is a smoke test which will check system for leaks, this is about $100 to have done at a shop. I would consider just replacing the fuel cap to see if that helps. Let me know if you have questions, thanks.
