      *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.

        *1 SST (Hose)
        *2 Fuel Pipe
        *3 SST (Clip)
        *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

      2. A00DPT3E10

        Install the O-ring onto the fuel injector assembly.

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

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

      4. Install a vinyl tube onto the injector.

        CAUTION:

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

      5. Put the injector into a graduated cylinder.

        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

        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.

        Standard
        1 drop or less every 12 minutes
