PO442-EVAP system small leak detected...Probable causes...Failed vent solenoid, Loose/missing fuel cap (NOT), purge solenoid malfunction,EVAP hose faulty.
PO 446-Faulty vent solenoid, Poor electrical connection, open or short circuit condition

All 3 codes include Vent Solenoid malfunction as probable cause...
Have not yet tried to reset VCS light...Thought I'd wait till I got the CEL problem fixed, hoping the VSC light would then go away...AUTO ZONE DOES NOT CARRY THE PART...I've checked on line but cannot locate a vent solenoid part...
What and where is this part located??? Clueless in Las Vegas...Bobby...

PS...My phone # is 702 328-8866...If you've got the time maybe you can call..

This part you are having issues with is generally located on or around the charcoal canister on almost all vehicles that I can think of... I would have thought AZ would carry that, but you might try Napa and O'Reillys... It is probably named something more along the lines of Vapor Solenoid Valve I would first locate it and check the electrical connections...

Please include the make, model and year of your car so that we can be of more help...
