FUEL INJECTOR(for Port Injection) INSPECTION

PROCEDURE


  1. INSPECT FUEL INJECTOR ASSEMBLY

    A000TLJE03
    *1 Component without harness connected: (Fuel Injector)

    1. Check the resistance of the injector.


      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 resistance is not as specified, replace the injector.

    2. Inspect the injection volume.

      CAUTION:

      This test involves high-pressure fuel and electricity. Take all precautions regarding safe handling of both the fuel and electrical components. Perform this test in a safe area, and avoid any sparks or flames. Do not smoke.


      1. A000YNL

        Remove the fuel pipe clamp.

      2. A000UAYE71
        *1 Pinch
        *2 Pull

        Pinch the connector and disconnect the fuel tube.

        Note

        Do not use any tools in this procedure.

        Tech Tips

        If the connector and tube are stuck, pinch the connector and push and pull the tube to disconnect them.

      3. A000TG5E08
        *1 SST (Hose)
        *2 SST (Hose Band)
        *3 Fuel Pipe
        *4 Fuel Tube Connector

        Connect SST to the vehicle side fuel pipe.

        SST
        09268-31014   ( 09268-41500, 09268-41700, 95336-08070 )

      4. Install a new O-ring to the fuel injector.

      5. A000TT5E07

        Install SST and the tube to the fuel injector.

        SST
        09268-31014   ( 09268-41700, 09268-41300, 09268-41600 )

        Note


        • Make sure that SST (adapter) and SST (clamp) are not loose and do not rattle.

        • Install a suitable vinyl tube to the injector to contain any gasoline spray.

      6. A000YH6E04
        Text in Illustration
        *1 Lock
        *2 SST (Tie Band)

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

        SST
        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.

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

      8. A000YEVE05
        *1 SST (Wire)

        Put the injector into a graduated cylinder.

        CAUTION:

        Install a strong rubber tube onto the injector to prevent gasoline from splashing.

      9. Operate the fuel pump (turn the power switch on (IG)).

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

        SST
        09842-30090
        Standard injection volume
        84 to 102 cc (5.1 to 6.2 cu. in.) per 15 seconds
        Difference between each injector: 18 cc (1.1 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.

    3. Check for leakage.


      1. A000YZW

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

        Standard fuel drop
        1 drop or less in 20 minutes
