FUEL SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK FUEL PUMP WITH FILTER ASSEMBLY OPERATION AND INSPECT FOR FUEL LEAK


    1. Check fuel pump with filter assembly operation.


      1. Connect the GTS to the DLC3.

      2. Turn the power switch on (IG) and turn the GTS on.

        Note

        Do not start the engine.

      3. Enter the following menus: Powertrain / Engine / Active Test / Activate the Circuit Relay.


        Powertrain > Engine > Active Test
        Tester Display
        Activate the Circuit Relay

      4. Check for pressure in the fuel tube sub-assembly from the fuel line. Check that sounds of fuel flowing from the fuel tank assembly can be heard. If no sound can be heard, check the fuel pump with filter assembly, ECM and wiring connectors.

    2. Inspect for fuel leaks.


      1. Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.

    3. Turn the power switch off.

    4. Disconnect the GTS from the DLC3.

  2. CHECK FUEL PRESSURE


    1. Discharge the fuel system pressure.

    6. Remove the cowl body mounting reinforcement LH.

      Click here

    7. Remove the outer cowl top panel sub-assembly.

      Click here

    8. Measure the auxiliary battery voltage.

      Standard Voltage
      11 to 14 V

    9. Disconnect the cable from the negative (-) auxiliary battery terminal.

      Note

      When disconnecting the cable, some systems need to be initialized after the cable is reconnected.

    10. B006HG2C02
      *a Open
      B006IKP Pull

      Open the cover of the fuel pipe clamp and remove the fuel pipe clamp from the fuel tube connector.

    11. A003MOK

      Disconnect the fuel tube sub-assembly from the fuel pipe.

      Click here

    12. B006IY4C03
      *a SST (Pressure Gauge)
      *b SST (Hose Joint)
      *c SST (Hose)
      *d SST (T-joint)
      *e SST (Fuel Tube Connector)
      *f SST (Hose Band)

      Install SST (EFI fuel pressure gauge) as shown in the illustration.

      SST
      09268-45101   ( 09268-41260, 09268-41280, 09268-41700, 95336-08070 )
      09268-00010   ( 09268-00020, 09268-00030 )

    13. Wipe up any spilled fuel.

    14. Connect the cable to the negative (-) auxiliary battery terminal.

      Note

      When disconnecting the cable, some systems need to be initialized after the cable is reconnected.

      Click here

    15. Connect the GTS to the DLC3.

    16. Turn the power switch on (IG) and turn the GTS on.

      Note

      Do not start the engine.

    17. Enter the following menus: Powertrain / Engine / Active Test / Activate the Circuit Relay.


      Powertrain > Engine > Active Test
      Tester Display
      Activate the Circuit Relay

    18. Measure the fuel pressure.

      Standard Fuel Pressure
      304 to 343 kPa (3.1 to 3.5 kgf/cm2, 44 to 50 psi)

      • If the fuel pressure is more than the standard, replace the fuel pressure regulator assembly.

      • If the fuel pressure is less than the standard, check the fuel hoses and their connections, fuel pump with filter assembly, fuel filter and fuel pressure regulator assembly.

    19. Disconnect the GTS from the DLC3.

    20. Put the engine in inspection mode (maintenance mode).

      Click here

    21. Start the engine.

    22. Measure the fuel pressure at idle.

      Standard Fuel Pressure
      304 to 343 kPa (3.1 to 3.5 kgf/cm2, 44 to 50 psi)

      Tech Tips

      Refer to Standard Idle Speed.

      Click here

    23. Stop the engine.

    24. Check that the fuel pressure remains as specified for 5 minutes.

      Standard Fuel Pressure
      147 kPa (1.5 kgf/cm2, 21 psi) or more

      If the result is not as specified, check the fuel pump with filter assembly, fuel pressure regulator assembly and/or fuel injector assemblies.

    25. After checking the fuel pressure, disconnect the cable from the negative (-) auxiliary battery terminal and carefully remove SST to prevent fuel from spraying.

      Note

      When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
