Description

The evaporation control system prevents the emission of fuel tank vapors into the atmosphere. When fuel evaporates
in the fuel tank, the vapors pass through vent hoses or tubes to an activated carbon filled vapor canister. The vapor
canister temporarily holds the fuel vapors. The Engine Control Module (ECM) allows intake manifold vacuum to draw
fuel vapors into the engine to be burned during certain operating conditions.

Operation

1 - Fuel Tank
2 - Fuel Vapor
3 - Vapor Canister
4 - Vapor Canister Vent
5 - Hose
The ECM will only energize the vapor canister control valve solenoid when the engine is at operating temperature,
but will de-energize it during periods of deceleration. When de-energized, no vapors are purged. The pulse-width
modulated canister control valve modulates the fuel vapor purge rate from the vapor canister and fuel tank to the
engine intake manifold.
