Can anyone tell me where the Evap Canister is located on a 2007 Entourage. I have an engine code coming up that says something about a vent valve close malfunction. This is the second time since ive owned it.. Previously i took it to the dealer 60 miles away and they said it was a filter of some sort that was clogged with dirt and mud.. Of the 60000 miles I have on this van, an estimated 15K is on gravel roads.. They said it was the dust from the gravel roads that caused the problem. I would like to see if this is something I can fix myself.
