Description

The evaporative emission control system prevents fuel vapor from accumulating in the fuel tank and escaping into the atmosphere. When fuel evaporates from the fuel tank, the vapor passes through the vent hoses or tubes into the charcoal canister, which temporarily holds the fuel vapor. If the ECM decides to draw the stored vapor into the combustion chambers under certain operating conditions, it uses intake manifold vacuum to move it.
