The system doesn’t require any maintenance, but faults can turn the check engine light, preventing the vehicle from passing an emission test.Ī car has a closed EVAP system, and it immediately captures the fuel tank vapors preventing them from escaping to the atmosphere. The evaporative emission control system is powerful enough to capture raw fuel evaporating from the fuel storage system.
