Evaporative Emissions System Small Leak Detected

The engine detected a small leak in the fuel vapor system, allowing a slow escape of fuel fumes that should normally be captured and burned. This could be caused by a small crack in a hose, a faulty purge valve, or a loose fitting in the fuel tank area. Although minor, the leak still violates emissions standards and should be repaired to pass inspection.
