GENERAL PROCEDURES
Canister Vent Solenoid Closing Procedure
CAUTION: 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.
1. Connect the scan tool and select the output test mode.
2. If PID monitors are not active, select PIDs.
3. Select the fuel tank pressure (FTP) and the volts (V) parameter identification (PID) for monitoring.
4. Select the ALL OFF mode.
5. Close the canister vent solenoid by pushing the START button on the scan tool.

GENERAL PROCEDURES
Evaporative Emission System Leak Test
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 two-
minute test period.

GENERAL PROCEDURES
Evaporative Emission Repair Verification Drive Cycle
Drive Cycle Recommendations
NOTE:
The following procedure is designed to execute and complete the evaporative emission repair
verification drive cycle and to clear the Ford P1000, inspection and maintenance (I/M) readiness code.
When the ambient air temperature is below 4.4°C (40°F) or above 37.8°C (100°F), or the altitude is
above 2,438 meters (8,000 feet), the EVAP monitor will not run. If the P1000 must be cleared in these
conditions, the powertrain control module (PCM) must detect them once (twice on some applications)
before the EVAP monitor can be bypassed and the P1000 cleared. The EVAP bypassing procedure is
described in the following drive cycle.
1. Most OBD II monitors will complete more readily using a steady foot driving style during cruise or acceleration modes. Operating the throttle in a smooth fashion will minimize the time
necessary for monitor completion.
2. Fuel tank level should be between one- half and three-quarters full with three- quarters full being
the most desirable.
3. The evaporative monitor can only operate during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth
fashion to minimize fuel slosh.
Drive Cycle Preparation
NOTE: For best results, follow each of the following steps as accurately as possible.
4. NOTE: This step bypasses the engine soak timer and resets OBD II monitor status.
Install the scan tool. Turn the key ON with the engine OFF. Cycle the key off, then on. Select
the appropriate vehicle and engine qualifier. Clear all diagnostic trouble codes (DTCs) and carry
out a PCM reset.
5. Begin to monitor the following PIDs: ECT, EVAPDC, FLI (if available) and TP MODE. Press Diagnostic Data Link, PCM, PID/Data monitor and record, press trigger to select each PID, then
start.
6. Start the engine without returning the key to the OFF position.
Preparation for Monitor Entry
WARNING: Strict observance of posted speed limits and attention to driving conditions

REMOVAL AND INSTALLATION
Evaporative Emission Canister
Removal and Installation
1. WARNING: The evaporative emission system contains fuel vapor and condensed
fuel vapor. Although not in large quantities, it still presents the danger of explosion or
fire. Disconnect the battery ground cable from the battery to minimize the possibility of
an electrical spark occurring, possibly causing a fire or explosion if fuel vapor or liquid
fuel is present in the area. Failure to follow these instructions may result in personal
injury.
Disconnect the battery ground cable. For additional information, refer to Section 414 - 01 .
2. Raise and support the vehicle. For additional information, refer to Section 100 - 02 .
3. Remove the left rear wheel. For additional information, refer to Section 204 - 04 .
4. WARNING: Do not smoke or carry lighted tobacco or open flame of any type when
working on or around any fuel- related component. Highly flammable mixtures are always
present and may be ignited. Failure to follow these instructions may result in personal
injury.
Disconnect the canister vent solenoid hose assembly.
5. Disconnect the connector.
6. Disconnect the evaporative emission (EVAP) canister purge outlet tube.
