WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.

E1 TEST THE EVAPORATIVE EMISSION (EVAP) RUNNING LOSS SYSTEM MONITOR
- Complete the evaporative emission repair verification drive cycle. Refer to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
- Are PCM DTCs retrieved?
Yes

For DTC P0442, P0455, P1443 or P1450, Refer to the PCM DIAGNOSTIC TROUBLE CODE (DTC) INDEX . For all other DTCs, Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE .

No

GO to E2.
E2 TEST FOR RESTRICTIONS IN THE EVAP SYSTEM FROM THE EVAPORATIVE EMISSION TEST PORT THROUGH THE CANISTER VENT SOLENOID
- Connect the Evaporative Emission System Leak Tester to the evaporative emissions test port.
- Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H₂ O).
- Does the pressure drop immediately?
Yes

CARRY OUT the evaporative emission system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. Refer to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE . GO to E3.

No

Go To PINPOINT TEST D: HISS WHEN OPENING FUEL CAP .
E3 TEST FOR A RESTRICTED TUBE BETWEEN THE FUEL TANK AND THE EVAPORATIVE EMISSION CANISTER
- Connect the Evaporative Emission System Leak Tester to the fuel filler pipe.
- Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H₂ O).
- Does the pressure drop immediately?
Yes

CARRY OUT the evaporative emission system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. Refer to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .

No

GO to E4.
E4 TEST FOR EVAP CANISTER TUBE OR FUEL VAPOR VENT VALVE ASSEMBLY BLOCKAGE
- Disconnect the fuel vapor vent valve assembly from the EVAP canister tube.
- Connect the EVAP System Leak Tester to the fuel filler pipe.
- Pressurize the EVAP system to 3.48 kPa (14 inches H₂ O).
- Does the pressure drop immediately?
Yes

INSTALL a new EVAP canister tube and/or fuel vapor tube(s) between the fuel tank and the EVAP canister and bracket assembly. CARRY OUT the evaporative emission system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. Refer to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .

No

INSTALL a new fuel vapor vent valve(s) or assembly. Refer to FUEL VAPOR CONTROL TUBE ASSEMBLY VALVE . CARRY OUT the evaporative emission system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
