F150 Pickup

WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2003 Mercury Sable, 2003 Mercury Mountaineer, 2003 Mercury Marauder, 2003 Mercury Grand Marquis, and 2003 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
  1. Testing EVAP Canister & Canister Vent Solenoid Flow -  Connect Evaporative Emissions System Leak Tester (134-00056) to fuel filler pipe. Pressurize system to 14 in. H2O (3.48 kPa). If pressure drops immediately, EVAP system is not blocked, go to step  5. If pressure does not drop immediately, go to next step.

  2. Testing Canister Vent Hose Assembly For Blockage

    Disconnect canister vent hose assembly from EVAP canister. EVAP canister is under rear of vehicle near left frame rail. Pressurize system to 14 in. H2O (3.48 kPa). If pressure does not drop immediately, go to next step. If pressure drops immediately, replace canister vent solenoid hose 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.

  3. Testing Canister Vent Solenoid For Blockage

    Remove canister vent solenoid. Canister vent solenoid is located next to EVAP canister. Pressurize system to 14 in. H2O (3.48 kPa). If pressure does not drop immediately, go to next step. If pressure drops immediately, 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.

  4. Testing EVAP Canister For Blockage

    Disconnect EVAP purge outlet tube from EVAP canister. Pressurize system to 14 in. H2O (3.48 kPa). If pressure does not drop immediately, replace the EVAP purge outlet tube between the EVAP test port and EVAP canister. Repeat step  1 to verify the repair. Then go to next step. If pressure drops immediately, replace EVAP canister. Reconnect all components. Repeat step  1 to verify the repair. Then go to next step.

  5. Testing EVAP Fuel Vapor Vent Valve(s) Or Assembly

    Disconnect battery ground terminal. Connect leak tester to fuel filler pipe. Pressurize system to 14 in. H2O (3.48 kPa). If pressure drops immediately, reconnect all disconnect components. Perform evaporative emissions system leak test. See EVAPORATIVE EMISSIONS SYSTEM LEAK TEST . If pressure does not drop immediately, replace fuel vapor vent valve(s) or EVAP canister assembly. After repairs, 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.
