        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
        1 - 2 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. Remove the EFI fuel pipe clamp Click here.

      2. Disconnect the fuel tube sub-assembly Click here.

        *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
        09268-31014   ( 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 then install the O-ring to the port fuel injector assembly.

        *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
        09268-31014   ( 09268-41600, 09268-41300, 09268-41700, 95336-08070 )

        *b SST (Tie Band)

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

        09268-31014   ( 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.

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

      8. 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.

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

      10. Operate the fuel pump Click here.

        *a SST (EFI Inspection Wire H)

        Connect SST (EFI inspection wire H) 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
        09842-30080
        Standard Injection Volume:
        Tester Connection Condition Specified Condition

        Positive (+) battery terminal -

        Negative (-) battery terminal

        		 Per 15 seconds 54 to 65 cc (3.3 to 4.0 cu. in.)
        Difference between Each Port Fuel Injector Assembly
        11 cc (0.7 cu. in.) or less

        Note


        • Make sure that SST (EFI inspection wire H) 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.

    3. Check for leaks.


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

        Standard Fuel Drop
        1 drop or less per 14 minutes

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