Hi-- I have a 2009 Journey. About a week ago, the engien light came on. It is running fine, no issues. I took it to AutoZone and had the code read- it showed code P0660-dual plane intake system dash control solenoid. Does anyone have any idea what this coiuld be? We bout it used from the dealership-had 27,000 miles on it, not has 67,000. Wewould prefer to try and fix it ourselves instead of taking it right away to the dealer. Thanks for any help..
