Hyundai Sonata: Description and Operation
Description
The Evaporative Emission Control System prevents fuel vapor stored in
fuel tank from vaporizing into the atmosphere. When the fuel evaporates in the
fuel tank, the vapor passes through vent hoses or tubes to a canister filled
with charcoal.
The canister temporarily holds the vapor in the charcoal. The ECM will
control the system in order to draw the gathered vapor into the combustion chambers
during certain operating conditions. Engine manifold vacuum is used to draw
the vapor into intake manifold.
