    2005 Prius 170k miles. Car threw code P0446.
    Great, a very generic evap leak. Well I took the good ol' techstream out and ran all the EVAP tests I could. Every test came back nearly perfect except the one labeled "CCV". Min:0.0s Max: 3.8s. My test resulted in 3.9s. I had a look underneath the car and couldn't find or hear any vacuum leaks while the tests were being done. Is this a sign of a sticking valve? I think I might just replace it but I'm having a hard time finding it and what part # it may be. Any help is appreciated :)
