Evaporative Emission Canister Assembly Leak Test

Evaporative Emission System Tester:

Special Tools Desired


CAUTION: The evaporative emission system must not be pressurized to more than 3.48 kPa (14 inches H2O) or damage to the evaporative emission system may occur.

1. Connect the Evaporative Emission System Leak Tester to the evaporative emission canister port.
2. Apply 12 volts to the canister vent solenoid.
3. Pressurize the evaporative emission canister to 3.48 kpa (14 inches H2O).
4. Monitor the system for two minutes, the canister fails leak test if the pressure falls below 2.0 kPa (8 inches H2O).
5. Repair any leaks as required.
6. Repeat the Leak Test-Evaporative Emission Canister and Bracket Assembly until the system remains above 2.0 kPa (8 inches H2O) after the two-minute test period.
