It sounds OK, Vacuum in the tank is the bad thing (I've noticed that the temperature outside effects the amount of pressure in my tank, and also it varies depending on the amount of fuel inside, and whether or not i've been on the highway just before checking the cap).

You may just need to replace the solenoid, but there is a few other components that can cause the code; like the charcoal canister itself (it can fill up with gas), the EVAP pressure control valve (the diaphragm can go bad inside it), maybe checking the lines going to the Purge solenoid for any lodged charcoal particles .

^There's a diagram of the EVAP canister system in this thread.
