Pinpoint Test F: Unable To Refuel (ORVR)

WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
  1. F1 TEST THE FUEL FILLER PIPE AND THE FUEL FILLER PIPE CHECK VALVE 
    • Remove the fuel filler cap.
    • Connect the Evaporative Emission System Tester to the fuel filler pipe.
    • Close the canister vent solenoid. Refer to CANISTER VENT SOLENOID CLOSING PROCEDURE .
    • Access PCM PID FTP V.
    • Pressurize the EVAP System to 3.48 kPa (14 inches H 2 O).
    • Is PID FTP V reading 3.11 kPa to 3.86 kPa (12.5 to 15.5 inches H 2  O) (4.22 to 4.90 volts)? 
    1. Yes  : GO to F2.
    2. No  : INSTALL a new fuel filler pipe and the fuel tank fuel filler pipe check valve. CARRY OUT the evaporative emissions repair verification drive cycle. REFER to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
  2. F2 TEST THE EVAP SYSTEM FOR RESTRICTION 
    • Connect the Evaporative Emission System Tester to the fuel filler pipe.
    • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
    • Does the system pressurize? 
    1. Yes  : GO to F3.
    2. No  : CARRY OUT the evaporative emissions system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emissions repair verification drive cycle. REFER to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
  3. F3 TEST FOR CANISTER VENT HOSE BLOCKAGE 
    • Remove the canister vent hose from the canister vent solenoid.

    • Connect the Evaporative Emission System Tester to the fuel filler pipe.
    • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H 2 O).
    • Does the system pressurize? 
    1. Yes  : GO to F4.
    2. No  : INSTALL a new canister vent hose. CARRY OUT the evaporative emissions system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emissions repair verification drive cycle. REFER to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
  4. F4 TEST FOR CANISTER VENT SOLENOID BLOCKAGE 
    • Remove the canister vent solenoid from the EVAP canister.

    • Connect the Evaporative Emission System Tester to the fuel filler pipe.
    • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
    • Does the system pressurize? 
    1. Yes  : GO to F5.
    2. No  : INSTALL a new canister vent solenoid. REFER to EVAPORATIVE EMISSION CANISTER VENT SOLENOID . CARRY OUT the evaporative emissions system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. REFER to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
  5. F5 TEST FOR EVAP CANISTER BLOCKAGE 
    • Disconnect the EVAP canister tube from the EVAP canister.

    • Connect the Evaporative Emission System Tester to the fuel filler pipe.
    • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
    • Does the system pressurize? 
    1. Yes  : GO to F6.
    2. No  : INSTALL a new EVAP canister. REFER to EVAPORATIVE EMISSION CANISTER . CARRY OUT the evaporative emissions system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. REFER to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
  6. F6 TEST FOR FUEL VAPOR VALVE TUBE ASSEMBLY BLOCKAGE 
    • Disconnect the EVAP canister tube from the fuel vapor valve tube assembly.
    • Connect the Evaporative Emission System Tester to the fuel filler pipe.
    • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
    • Does the system pressurize? 
    1. Yes  : INSTALL a new fuel vapor valve tube assembly. CARRY OUT the evaporative emissions system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emissions repair verification drive cycle. REFER to EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
    2. No  : INSTALL a new EVAP canister tube. CARRY OUT the evaporative emissions system leak test. Refer to EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, CARRY OUT the evaporative emissions repair verification drive cycle. REFER to the EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE .
