Evaporative Emission Canister Assembly Leak Test

Special Service Tool(s)

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 the leak test if the pressure drops below 1.49 kPa (6 inches H2O).
5. Repair any leaks as necessary.
6. Repeat the leak test until the canister and bracket assembly pressure remains above 1.49 kPa (6 inches H2O) after the two-minutes test period.
