Blackwood, Econoline, Escape, Excursion, Expedition, Explorer, F250-550 Super Duty Pickup, Mountaineer, Navigator, Ranger & Windstar

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2002 Mercury Sable, 2002 Mercury Mountaineer, 2002 Mercury Grand Marquis, 2002 Mercury Cougar, and 2002 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
  1. Testing EVAP Canister, Canister Vent Solenoid Flow & Canister Vent Hose -  Connect Evaporative Emissions System Leak Tester (134-00056) to fuel filler pipe. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure drops immediately, EVAP system is not blocked, go to step  6. On models equipped with a canister vent hose assembly, if pressure does not drop immediately, go to next step. On models equipped with canister vent solenoid, if pressure does not drop immediately, go to step  3. On all other models, if pressure does not drop immediately, go to step  4.

  2. Testing Canister Vent Hose Assembly For Blockage

    Disconnect canister vent hose assembly from EVAP canister. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure does not drop immediately, go to next step. If pressure drops immediately, replace canister vent solenoid hose assembly. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURE under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  3. Testing Canister Vent Solenoid For Blockage

    Remove canister vent solenoid. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure does not drop immediately, go to next step. If pressure drops immediately, replace canister vent solenoid. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURE under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  4. Testing EVAP Canister

    Disconnect EVAP canister tube from fuel tank at "F" fitting from EVAP canister. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure does not drop immediately, go to next step. If pressure drops immediately, replace EVAP canister. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURE under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  5. Testing EVAP Canister Tube Or Fuel Vapor Vent Valve For Blockage

    Disconnect fuel vapor valve assembly from EVAP canister tube. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure drops immediately, replace EVAP canister tube and/or fuel vapor valve tube between fuel tank and EVAP canister and bracket assembly. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURE under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed. If pressure does not drop immediately, replace fuel vapor valve(s) or assembly. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURE under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  6. Testing For Blockage Between EVAP Canister Purge Valve & Fuel Tank

    Remove fuel tank fuel vapor hose from EVAP canister purge valve. Turn ignition on. On models with a canister vent solenoid, using scan tool, close canister vent solenoid. Select OUTPUT TEST MODE, FTP and FTP V PID. Select ALL OFF mode. Press START button on scan tool to close canister vent solenoid. On models without canister vent solenoid, plug canister vent hose assembly or plug canister vent cap. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure does not drop immediately, replace fuel vapor hose. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURE under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed. If pressure drops immediately, system has passed. Reconnect all components. On models with a canister vent solenoid, perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURE under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed. On models without canister vent solenoid, perform DRIVE CYCLE PROCEDURE under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.
