    INSPECT FUEL INJECTOR ASSEMBLY


    1. Inspect the resistance.


      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 20°C (68°F) 11.6 to 12.4 Ω

        If the result is not as specified, replace the fuel injector assembly.

    INSPECT INJECTION VOLUME AND LEAKAGE

    CAUTION:

    • This test involves high-pressure fuel and electricity.

    • Take every precaution regarding safe handling of both the fuel and the electrical parts.

    • Perform this test in a safe area, and avoid any sparks or flame.

    • Do not smoke.


    1. A01BGZME02

      Assemble SST as shown in the illustration.

      *d SST (Union No. 7)
      *e SST (Hose Band)

    2. Discharge the fuel system pressure (Click here).

    3. Disconnect the No. 1 fuel hose (fuel tube connector) from the fuel tube.

    4. Remove the 2 bolts and disconnect the fuel pressure regulator assembly from the fuel delivery pipe sub-assembly.

      Note:

      Do not disconnect the No. 2 fuel hose from the fuel pressure regulator assembly.

    5. A01BI1XE03

      Connect SST to the fuel tube.

      *1 Fuel Tube
      *a SST (Fuel Tube Connector)
      CAUTION:

      Always read the precautions (Click here) before connecting the fuel tube connector (quick type).

    6. A01BDSYE03

      Connect SST to the fuel pressure regulator assembly fuel inlet with the 2 bolts.

    7. Install the O-ring to the fuel injector assembly.

    8. A01BER5E03

      Assemble SST as shown in the illustration.

      09268-31014 09268-41110 09268-41310 09268-41700 95336-08070

      Note:

      Make sure that SST (adapter) and SST (clamp) are not loose and do not rattle.

    9. A01BFP7E04

      Pass SST (tie band) through the loop on the handle of SST (clamp) to secure SST (clamp) to SST (adapter).

      Table 5. Text in Illustration
      *a SST (Tie Band)
      *b Lock
      Note:

      • As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.

      • Before using SST (tie band), make sure that there is no deterioration, damage or cracks. If there are any abnormalities, replace SST.

      Tip:

      When removing SST (tie band), disengage the lock.

    10. Check that SST (clamp) and SST (adapter) cannot be easily separated.

    11. Install a vinyl tube to the fuel injector assembly.

    12. Put the fuel injector assembly into a graduated cylinder.

      Note:

      Install a suitable vinyl tube onto the fuel injector assembly to contain the gasoline spray.

    13. Operate the fuel pump.


      1. Turn the ignition switch to ON.

        Note:

        Do not start the engine.

      2. Turn the intelligent tester on.

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

    14. A01BEJ4E03

      Connect SST (EFI inspection wire H) to the fuel injector assembly and the battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 times.

      09842-30080
      Standard injection volume
      71 to 86 cm3 (4.3 to 5.2 cu. in.) in 15 seconds
      Standard difference between each fuel injector assembly
      15 cm3 (0.9 cu. in.) or less
      Note:

      Always turn the voltage on and off on the battery side, not the fuel pump side.

      If the result is not as specified, replace the fuel injector assembly.

    15. A01BDY6E01

      Check the fuel leakage.


      1. In the condition above, disconnect the test probes of SST (EFI inspection wire H) from the battery and check the fuel leakage rate from the fuel injector assembly.

        Standard fuel drop
        1 drop or less per 12 minutes
