2004 Ford Freestar V6-4.2L VIN 2SECTION Service Precautions
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.
- The canister vent solenoid must not be energized for more than nine 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.
