      *1

      Component without harness connected

      (Fuel Injector Assembly)

      Check 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 injector assembly.

    2. Check the injection volume.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near any naked flames.

        *3 SST (Hose Band)
        *4 SST (Fuel Tube Connector)
        *5 Retainer
        *6 O-Ring

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

        SST

        *4 O-Ring
        *5 SST (Clamp)
        *6 Vinyl Tube

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

        *1 SST (Tie Band)
        *a Lock

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

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

        Tech Tips

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

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

      6. Install a vinyl tube onto the injector.

        CAUTION:

        Install a suitable vinyl tube onto the injector to prevent gasoline from splashing out.

      7. Put the injector into a graduated cylinder.

        A01ISM9 Connect

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

        SST
        09842-30080
        Standard injection volume
        60 to 73 cc (3.7 to 4.5 cu. in.) per 15 seconds
        Difference between each injector
        13 cc (0.8 cu. in.) or less

        Note


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

        • Always do the switching at the battery side.

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

      Inspect for fuel leak.


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