    I've gotten the CEL the other day and the code read p0446, which is an Evap System Errorr. There was also a p0441 pending. I've tightened my gas cap and there seems to be pressure that I can hear releasing when I open it. Is my vapor canister bad or is it more likely the VSV under the hood?

    Its a 2004 Tacoma 3.4L engine.
