Evap 0446 code question

I have a 2004 Silverado and the CEL came on showing code 0446(evap vent solenoid) I replaced it 4 days ago and have been driving the truck. The scanner still shows "evap not ready" when I check all the emission systems. What else could be going on?

The Evap monitor is the hardest one to bring back online. Drive it for a while longer
