Vent Control Valve P0456 (evap leak)
I posted elsewhere that I was unable to clear my malfunction (check engine) light, but then I finally did. However, when it came on again the next day, I figured it was time to go to the dealer.
Iit was a very small evap leak at the vent control valve. They replaced the valve. So far (10 minutes driving) seems A-OK. :-) I had a similar complaint about a year ago and I know they found a small leak then but I don't think they did anything about it (obviously). They were probably hoping it would just go away, which it did for a year.
