Evaporative Emission Control Canister: Description and Operation

Fuel Vapor Canister

PURPOSE

Stores fuel vapor until purge operation occurs.

OPERATION

When the Engine Control Module (ECM) energizes the solenoid valve, manifold vacuum draws air through fitting 2 on the canister. Fresh air
being drawn into the bottom of the canister, "flushes" (purges) the canister of fuel vapors. The vapors flow into the engine and are burned in the
combustion process.
