FUEL SYSTEM(w/o Canister Pump Module) ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

      Note

      Do not start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.


      Powertrain > Engine and ECT > Active Test
      Tester Display
      Control the Fuel Pump / Speed

    5. Check the fuel pump operation.


      1. Check for pressure in the fuel inlet tube from the fuel line. Check that the sound of fuel flowing in the fuel tank can be heard.

        If there is no sound, check the C/OPN relay, fuel pump, ECM and wiring connector.

    6. Check for fuel leaks.


      1. Check that there are no fuel leaks after performing maintenance anywhere on the system.

        If there are fuel leaks, repair or replace parts as necessary.

  2. CHECK FUEL PRESSURE


    1. Using a voltmeter, measure the battery voltage.

    3. Disconnect the cable from the negative (-) battery terminal.

      Note


      • After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work.

    5. A01V8KQC01
      *1 SST (Pressure Gauge)
      *2 SST (Hose Joint)
      *3 SST (Hose)
      *4 SST (T Joint)
      *5 SST (Fuel Tube Connector)
      *6 SST (Hose Band)

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

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

    6. Wipe up any gasoline.

    7. Reconnect the cable to the negative (-) battery terminal.

    8. Start the engine.

    9. Measure the fuel pressure at idle.

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

      If the pressure is not as specified, check the fuel pump and injectors.

    10. After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST and the fuel tube connector to prevent fuel from spilling.

    11. Reconnect the fuel tube.
