Special Tool(s)

Evaporative Emission System Tester 310-F007 (134-00056) or equivalent
Worldwide Diagnostic System (WDS) 418-F224, New Generation STAR (NGS) Tester 418-F052, or equivalent scan tool

CAUTION: The evaporative emission system must not be pressurized to more than 3.48 kPa (14 inches H 2 O) or damage to the evaporative emission system may occur.

1. Connect the Evaporative Emission System Leak Tester to the evaporative emission test port.

2. Close the canister vent solenoid. For additional information, refer to Canister Vent Solenoid Closing Procedure in this section.

3. Pressurize the evaporative emission system to 3.48 kPa (14 inches H 2 O).

4. Monitor the system for two minutes. The system fails the leak test if the pressure falls below 2.0 kPa (8 inches H 2 O).

5. Repair any leaks as necessary.

6. Repeat the leak test until the system remains above 2.0 kPa (8 inches H 2 O) after the twominute test period.
