Except Tribute

  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 switch on, engine off. Connect scan tool to DLC. Select EVAPCV PID. Select ALL OFF mode. Press START button on scan tool to close Canister Vent (CV) 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 in appropriate SELF-DIAGNOSTICS 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). If system pressurizes, go to next step. 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 in appropriate SELF-DIAGNOSTICS article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  3. Testing Canister Vent Hose For Blockage

    Remove hose from CV 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 CV hose. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST  . If system passes, perform DRIVE CYCLE PROCEDURES appropriate SELF-DIAGNOSTICS article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  4. Testing EVAP Canister Vent Solenoid For Blockage

    Remove CV 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 CV solenoid. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST  . If system passes, perform DRIVE CYCLE PROCEDURES in appropriate SELF-DIAGNOSTICS article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  5. 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 in appropriate SELF-DIAGNOSTICS article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

  6. Testing Fuel Vapor Valve Tube Assembly For Blockage

    Disconnect EVAP canister tube at Fuel Vapor Vent (FVV) valve tube assembly. Attempt to pressurize system to 14 in. H2 O (3.48 kPa). If system pressurizes, replace FVV valve tube assembly. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST  . If system passes, perform DRIVE CYCLE PROCEDURES in appropriate SELF-DIAGNOSTICS 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 in appropriate SELF-DIAGNOSTICS article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.
