My check engine light is on and the code is P0446 Evaporative Emission Control System Vent Control malfunction.

Any suggestions on how to fix this

It may have come on because of a loose/bad gas cap, it must click 3 times after getting fuel. Or check to see if your evap cannister valve is working, they get dirt and stick
