Are you observing any symptoms other than the light coming on?

The evaporative system prevents hydrocarbon (HC) vapor escaping from the fuel tank into the atmosphere where they would form photochemical smog. Gasoline vapor is collected in the charcoal canister. The Canister Close Valve (CCV) closes off the air inlet to the canister for leak detection of the evaporative emission system. The CCV also prevents fuel vapors from escaping from the canister. When the engine purges HC vapor from canister, the clean air comes into the canister through canister air-filter and CCV.

I went to the Hyundai Webtech site. I can not find that code. However, I did find these two.
 
DTC P0445
 
EVAP Emission Control System Purge Control Valve Circuit Shorted
 
and
 
DTC P0447
 
EVAP Emission Control System Vent Circuit Open
 
Both give detailed instructions on how to test and correct. Visit the Hyundai webtech site for more info.

I ran into that issue early on. It has something to do with Java and Microsfts Virtual Machine software. All I did was upgrade my explorer to 7 and added Sun Java. Worked fine after that. If you continue to have issues let me know and I will take screen shots for you and send them via e-mail.

I sent both - Screen prints and the text only versions. I also included two other charts that " DO " list your code 446. Review them all. I hope it helps. Let me know how you make out.

UPDATE:
 
Sorry to keep the rest of you in the dark. Code 446 seems to be missing from the list on the Hyundai Webtech site. Codes just before and after ( In this case 444/445/447 ) detail diagnostics on the electrical part of the system. The site allows you to e-mail the document to someone but when it arrives the pictures are missing. Real strange. I created screen prints and placed them in a word doc and sent them to short79572. I also included two charts that do in fact list the code and seem to point to a Canister Close Valve Malfunction or Stuck in valve closed position (CCV)
Faulty CCV.
