        Condition

        Specified Condition

        1 - 2

        20°C (68°F)

        11.6 to 12.4 Ω

        *1

        Component without harness connected

        (Fuel Injector Assembly)

        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. A273749E02

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

        O-Ring

      2. Install the O-ring onto the fuel injector.

      3. A273750E02

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

      4. A273752E02

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

        Lock
        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.

        Tip:

        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.

      8. Operate the fuel pump (Click here).

      9. A273751E02

        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.

        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

        Connect
        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.

    3. A132391

      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.

        Fuel drop

        1 drop or less every 12 minutes
