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. H2O (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 CYCLES in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

Testing EVAP System For Restriction

Attempt to pressurize system to 14 in. H2O (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 CYCLES in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

Testing Canister Vent Hose For Blockage

Remove canister vent hose from canister vent solenoid. Attempt to pressurize system to 14 in. H2O (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 CYCLES in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

Testing Canister Vent Solenoid For Blockage

Remove canister vent solenoid from EVAP canister. Attempt to pressurize system to 14 in. H2O (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 CYCLES in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

Testing EVAP Canister For Blockage

Remove EVAP canister tube from EVAP canister. Attempt to pressurize system to 14 in. H2O (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 CYCLES in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed.

Testing Fuel Vapor Control Valve Tube Assembly For Blockage

Disconnect EVAP canister tube at fuel vapor control valve tube assembly. Attempt to pressurize system to 14 in. H2O (3.48 kPa). If system pressurizes, replace fuel vapor control valve tube assembly. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If system passes, perform DRIVE CYCLES in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & 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 CYCLES in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article.
