Print

Proper operation of the evaporative emissions system is important to maintaining low emissions levels. A malfunctioning evaporative system will allow fuel vapors to escape into the atmosphere, polluting the atmosphere.

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

Although the manufacturer does not give a specific inspection schedule, it is a good idea to inspect the evaporative canister at 2,000 mile (48,20 km) intervals.
