Evaporative Emission Control Canister: Description and Operation

Evaporative Emissions Canister:

The Carbon Canister stores fuel vapors from the fuel tank until the vehicle is operated, at which time, the vapors will be drawn by engine vacuum into the engine for consumption. Purging of the fuel vapors to the engine occurs only when certain engine conditions are met and is regulated by the Canister Purge (CANP) Solenoid as controlled by the ECA.
