P00FE — EVAP System Tank Vapor Line Restricted/Blocked
The EVAP tank vapor line is restricted or blocked. Tank pressure cannot equalize properly. The evaporative system captures fuel vapor from the tank and purges it into intake; leaks or stuck purge valves leak hydrocarbons and cause emissions failures.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
