- Introduce smoke from the smoke machine emissions tester into the EVAP system. For additional information, refer to the manufacturer's instructions.
- Use the halogen light provided with the smoke machine emissions tester to look for smoke coming from the EVAP system. This will indicate a leak point.
- Repair any leaks as necessary.
- Repeat the leak test until the system passes.
CAUTION:
The canister vent solenoid must not be energized for more than 9 minutes at one time. Once the canister vent solenoid is energized and de-energized, adequate time must be allowed for the component to cool adequately. Failure to allow the component to cool may create a false failure in the diagnostics, causing unnecessary repairs.
