Hi all, I'd like to start a new thread on this since the others seem to be six or more years old. I have a 2004 CRV showing a p0497 check engine code (EVAP system low purge flow.) Anyone else have recent experience with this? I saw on another thread that it can get "very expensive", I'm wondering how much. I'm trying to work on it myself, so technical suggestions are appreciated too. Thanks!
