Continental, Crown Victoria, Escape, Grand Marquis & Town Car

  1. Testing Fuel Filler Pipe & Check Valve -  Remove fuel filler cap. Connect Evaporative Emissions System Leak Tester (134-00056) to fuel filler pipe. Turn ignition on. 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. Access PCM PID FTP V. Pressurize system to 14 in. H2 O (3.48 kPa). If PCM PID FTP V is 4.22-4.90 volts, go to next step. If PCM PID FTP V is not as specified, replace fuel filler pipe and check valve. Perform DRIVE CYCLE PROCEDURES under ADDITIONAL SYSTEM FUNCTIONS in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  2. Testing EVAP System For Restriction

    Attempt to pressurize system to 14 in. H2 O (3.48 kPa). On Crown Victoria, Escape, Grand Marquis and Town Car, if system pressurizes, go to next step. On all other models, if system pressurizes, go to step  4. On all models, if system does not pressurize, remove tester from fuel filler pipe and install fuel filler cap. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURES under ADDITIONAL SYSTEM FUNCTIONS in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  3. Testing Canister Vent Solenoid Remote Vent Hose Assembly For Blockage

    Disconnect canister vent solenoid remote vent hose from in-line connector. Pressurize system to 14 in. H2 O (3.48 kPa). If system does not pressurize, repair or replace canister vent solenoid remote vent hose. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system pressurizes, go to next step.

  4. Testing Canister Vent Hose For Blockage

    Remove canister vent hose from canister vent solenoid. Attempt to pressurize system to 14 in. H2 O (3.48 kPa). If system pressurizes, go to next step. If system does not pressurize, replace canister vent hose. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURES under ADDITIONAL SYSTEM FUNCTIONS in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  5. Testing Canister Vent Solenoid Or Dust Separator For Blockage

    Remove canister vent solenoid from EVAP canister. Attempt to pressurize system to 14 in. H2 O (3.48 kPa). If system pressurizes, go to next step. If system does not pressurize, replace canister vent solenoid. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURES under ADDITIONAL SYSTEM FUNCTIONS in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  6. Testing EVAP Canister For Blockage

    Remove EVAP canister tube from EVAP canister. Attempt to pressurize system to 14 in. H2 O (3.48 kPa). If system pressurizes, go to next step. If system does not pressurize, replace EVAP canister. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURES under ADDITIONAL SYSTEM FUNCTIONS in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  7. Testing Fuel Vapor Valve Tube Assembly For Blockage

    Disconnect EVAP canister tube at fuel vapor valve tube assembly. Attempt to pressurize system to 14 in. H2 O (3.48 kPa). If system pressurizes, replace fuel vapor valve tube assembly. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURES under ADDITIONAL SYSTEM FUNCTIONS in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed. If system does not pressurize, replace EVAP canister tube. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLE PROCEDURES under ADDITIONAL SYSTEM FUNCTIONS in SELF-DIAGNOSTICS - EEC-V - CNG & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.
