WARNING: This page is about a different variant/trim than selected.
  1. Testing Evaporative Emission Running Loss System Monitor -  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 PCM DTCs P0442, P0455, P1443 or P1450 are retrieved, see EVAPORATIVE EMISSIONS DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article for appropriate test procedure. If any other PCM DTCs are retrieved, see DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article for appropriate test procedure. If no PCM DTCs are retrieved, go to next step.

  2. Testing For Restriction In EVAP Test Port Through Canister Vent Solenoid

    Connect Evaporative Emissions System Leak Tester (134-00056) to test port. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure drops immediately, 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, go to TEST D .

  3. Testing For Restriction Between Fuel Tank & EVAP Canister

    Move EVAP tester to fuel filler pipe. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure drops immediately, 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, go to next step.

  4. Testing EVAP Canister Tube Or Fuel Vapor Vent Valve Blockage

    Disconnect fuel vapor vent valve from EVAP canister tube. Pressurize system to 14 in. H2 O (3.48 kPa). If pressure drops immediately, replace fuel vapor tubes between fuel tank and EVAP canister and/or EVAP canister tube. 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 vent valve. 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.
