Evaporative Emission Canister Assembly Leak Test

Evaporative Emission System Tester:

Special Tools Recommended

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

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