Evaporative Canister


The evaporative emission system stores gasoline vapors which rise from the sealed fuel system. The system prevents these unburned hydrocarbons from polluting the atmosphere. It consists of a charcoal vapor storage canister, valves and interconnecting lines. The system should be inspected every 60,000 miles (96,000 km).

For more information on the evaporative emission system, please refer to Driveability & Emission Controls of this guide.
