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. Using scan tool, close Canister Vent (CV) solenoid. Select EVAPCV PID. Select ALL OFF mode. Press START button on scan tool to close 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.

Testing EVAP System For Restriction

Open 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, 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.

Testing Fuel Vapor Control Valve Tube Assembly For Blockage

Disconnect EVAP emission canister purge outlet tube. Attempt to pressurize system to 14 in. H₂ O (3.48 kPa). If system does not pressurize, go to next step. If system pressurizes, replace fuel tank 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.

Testing Check Valve For Blockage

Remove EVAP canister and bracket assembly from vehicle. Connect Evaporative Emissions System Leak Tester (134-00056) to EVAP canister purge outlet tube. Disconnect check valve assembly. 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 check valve. 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.

Testing Dust Separator For Blockage

Disconnect dust separator and hose assembly. 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 dust separator and hose assembly. 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.

Testing EVAP Canister Vent Solenoid For Blockage

Remove EVAP emission canister vent solenoid. Connect Evaporative Emissions System Leak Tester (134-00056) to EVAP canister purge outlet tube. 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 emission canister vent solenoid. 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.

Testing EVAP Canister For Blockage

Remove EVAP emission canister purge outlet tube. Connect Evaporative Emissions System Leak Tester (134-00056) to EVAP emission canister purge outlet tube. Attempt to pressurize system to 14 in. H₂ O (3.48 kPa). If system pressurizes, replace EVAP emission canister purge outlet tube. If system does not pressurize, replace EVAP emission canister. 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.
