Functional Description - Charcoal Canister

WARNING: This page is about a different variant/trim than selected.

A maintenance free vapor canister is used on all vehicles. The Charcoal Canister is filled with granules of an activated carbon mixture. Fuel vapors entering the Charcoal Canister are absorbed by the charcoal filter until they can be drawn into the Intake Manifold during purging and burned by the engine.
