CEL: PO 446 Engine Code - help!

DTC P0446: Evaporative Emission Control System Vent Control

Just pulled this code. I intalled a Turbo Timer and HUD display, but don't see how that's related. Any ideas?

Back from the dead. Ive been getting the same code P0446, was random now its frequent and annoying. Has anyone had the same code and corrected it or dealer fixed? Might just leave it to the dealer.

For 05's outside of CA how long is emissions stuff covered?
