FUEL INJECTOR INSPECTION


  1. INSPECT FUEL INJECTOR ASSEMBLY

    A01GIDUE01

    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 the electricity. Perform this test in a safe area, and avoid any sparks or flames. Do not smoke.


      1. A01GJ12

        Remove the fuel pipe clamp.

      2. A01GM9XE01

        Disconnect the fuel tube.

      3. A01GN6VE01

        Connect SST to the fuel pipe (the vehicle side).

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

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

      5. A01GI0PE01

        Install SST and 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.

        *1 SST (Tie Band)
        *2 Lock

        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. A01GNTFE01

        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 engine 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. A01GI6P

        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
