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.
See Figures 1, 2 and 3
Inspect all vapor hoses for tight connections. Carefully inspect hoses for damage and replace as necessary. Hoses, especially molded plastic hoses, are prone to cracking. Replace hoses as necessary.
Inspect the evaporative canister for damage. Replace canister as necessary.
Inspect the evaporative canister valves for proper operation using the procedures in Driveability & Emissions Controls of this repair guide. If valves are faulty, replace the canister as an assembly.
