My check engine light came on this morning. OBDII returned code P0442: Evaporative System Malfunction. Anyone have any experience with this code? Can anyone post a diagram of the emissions system from a Ford shop manual? Thanks.
Engine does not sound different, no rough idle. I figure I'll start checking hose clamps in the emissions system, sniffing for hydrocarbon odor, checking the fuel filler neck, etc...
Details: 2006 FEH, 93,100 miles. First occurance of this code on this vehicle.
And yes, my gas cap was on tight
