      *1 Ohmmeter
      *a

      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.

        Tech Tips

        After replacing the fuel injector assembly, perform the "Inspection After Repairs" Click here.

    2. Check the operation.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near any open flames.

        *1 SST (Hose)
        *2 SST (Clip)
        *3 SST (Fuel Tube Connector)
        *4 Fuel Pipe
        *5 Retainer
        *6 O-ring

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

        SST

        *1 SST (Hose)
        *2 SST (Clip)
        *3 SST (Adapter)
        *4 SST (Clamp)
        *5 Vinyl Tube

        Install the new O-ring onto the fuel injector.

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

        SST
        09268-31013   ( 09268-41141, 09268-41410, 90467-13001, 95336-08070 )

      4. Put the injector into a graduated cylinder.

        CAUTION:

        Install a suitable vinyl tube onto the injector assembly to prevent gasoline splashes.

      5. Operate the fuel pump Click here.

      6. A01VJJSE38

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

        Difference between each injector
        12 cm3 (0.7 cu in.) or less

        CAUTION:

        Always do the switching at the battery side.

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

    3. A01VHAR

      Check for leaks.


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