        *a

        Component without harness connected

        (Port Fuel Injector Assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        E7-1(#7) - E7-2(#70) 20°C (68°F) 11.6 to 12.4 Ω
        E12-1(#8) - E12-2(#80) 20°C (68°F) 11.6 to 12.4 Ω
        E8-1(#9) - E8-2(#90) 20°C (68°F) 11.6 to 12.4 Ω
        E13-1(#10) - E13-2(#100) 20°C (68°F) 11.6 to 12.4 Ω
        E9-1(#11) - E9-2(#110) 20°C (68°F) 11.6 to 12.4 Ω
        E14-1(#12) - E14-2(#120) 20°C (68°F) 11.6 to 12.4 Ω

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

    2. Check the operation.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near an open flame.


      1. Discharge fuel system pressure.

      2. B006DA2C01
        *A for LHD
        *B for RHD

        Disconnect the fuel hose sub-assembly.

      3. B006FWBC19
        *a SST (Hose)
        *b SST (Hose Band)
        *c SST (Fuel Tube Connector)
        *d Fuel Pipe (Vehicle Side)

        Connect SST (fuel tube connector) to SST (hose) with SST (hose band), and then connect them to the fuel pipe (vehicle side).

        SST
        09268-31015   ( 09268-41500, 09268-41700, 95336-08070 )

        Note

        Make sure the SST (fuel tube connector) O-rings are not damaged and are free of foreign matter as they are used to seal the connections between the fuel tube connector and fuel pipe.

      4. Apply a light coat of gasoline to a new O-ring, and install the O-ring to the port fuel injector assembly.

      5. B006C4CC03
        *1 O-ring
        *a SST (Adapter)
        *b SST (Hose Band)
        *c SST (Clamp)
        *d SST (Hose)
        *e Vinyl Tube

        Connect SST (adapter) and SST (hose) to the port fuel injector assembly, and hold the port fuel injector assembly and union with SST (clamp).

        SST
        09268-31015   ( 09268-41410, 09268-41600, 09268-41700, 95336-08070 )

      6. Install a vinyl tube to the port fuel injector assembly.

        CAUTION:

        Install a suitable vinyl tube to the port fuel injector assembly to prevent fuel from spraying.

      7. B006BA9C01
        *a Lock
        *b SST (Tie Band)

        Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.

        SST
        09268-31015   ( 09268-41800 )

        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 wear, damage or cracks. If there are any abnormalities, replace SST.

        Tech Tips

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

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

      9. Set the port fuel injector assembly into a graduated cylinder.

      10. Connect the GTS to the DLC3.

      11. Turn the engine switch to ON.

        Note

        Do not start the engine.

      12. Turn the GTS on.

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


        Powertrain > Engine > Active Test
        Tester Display
        Activate the Circuit Relay
      14. B006G1ZC01
        *a SST (EFI Inspection Wire K)

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

        SST
        09842-30110
        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive (+) battery terminal - Negative (-) battery terminal Per 15 seconds 67 to 82 cc (4.1 to 5.0 cu.in.)
        Difference between Each Port Fuel Injector Assembly
        15 cc (0.9 cu.in.) or less

        Note


        • Make sure that SST (EFI inspection wire K) is securely connected.

        • Always switch the voltage on and off at the battery side, not the port fuel injector assembly side.

        If the injection volume is not as specified, replace the port fuel injector assembly.

      15. Turn the engine switch off.

      16. Disconnect the GTS from the DLC3.

    3. Check for leaks.


      1. Disconnect SST (EFI inspection wire K) from the battery and check for fuel leaks from the port fuel injector assembly.

        Standard Fuel Drop
        1 drop or less per 20 minutes

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

      2. Connect the fuel hose sub-assembly.
