Evaporative Canister


The Evaporative Emissions System is designed to eliminate the discharge of fuel vapor into the atmosphere. Fuel vapor from the fuel tank is drawn into the evaporative (EVAP) canister where it is temporarily stored, until it is purged from the canister to the engine, where it is burned during combustion.

The EVAP canister is located on the firewall at the driver's side of the engine compartment on 1993-98 vehicles (except 1998 California emissions). On 1998 California emissions vehicles and 1999-00 vehicles, the EVAP canister is located under the vehicle.


While the EVAP canister requires no maintenance, the factory recommends that the canister and related lines should be inspected every 30,000 miles (24,000 km) or every 24 months, whichever comes first. Any components that are cracked, brittle, or damaged should be replaced. Please refer to Driveability and Emission Controls, Emission Controls, Evaporative Emission Controls, Removal and Installation for the procedure.
