upper EVAP canister purge valve fitting. For additional information, refer to
the manufacturer's instructions.
- Connect the scan tool and open the EVAP canister purge valve.
- Using the scan tool, close the EVAP canister vent solenoid. For additional
information, refer to the manufacturer's instructions.
- Using the VACUTEC Smoke Machine Fuel Evaporative Emission Tester, pressurize
the EVAP system.
- Monitor the indicator flag on the VACUTEC Smoke Machine Fuel Evaporative
Emission Tester. If the measurement is below the indicator flag, the system
has passed the leak test and the test procedure is complete. If the measurement
is above the indicator flag, the system has failed the leak test. Proceed to
Phase 2.

a leak point.
- Repair any leaks as necessary.
- Repeat the leak test until the system passes.
