Re: 02 Sienna - DTC code 0446
Here is EG007-05
I would personally do this and then replace the CCV-vsv (they are known for being bad.) Its just a guess without the TOYOTA scan tool. You have to be able to watch the pressures and readings inside the tank to actually see where the leak or restriction is.
Good Luck.
