Evaporative Emission System Leak Test Procedure
WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
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.
- Connect the Evaporative Emission System Leak Tester to the evaporative emission test port.
- Close the canister vent solenoid. For additional information, refer to CANISTER VENT SOLENOID CLOSING PROCEDURE .
- Pressurize the evaporative emission system to 3.48 kPa (14 inches H2O).
- Monitor the system for two minutes. The system fails the Leak Test if the pressure falls below 2.0 kPa (8 inches H2O).
- Repair any leaks as required.
- Repeat the Leak Test until the system remains above 2.0 kPa (8 inches H2O) after the two-minute test period.
