FUEL INJECTOR (for Port Injection) INSPECTION


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. Measure the resistance of the fuel injector assembly.


      1. A015ZFVE05

        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 fuel injector assembly.

    2. Inspect the injection volume.

      CAUTION:

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


      1. A016175

        Remove the fuel pipe clamp.

      2. A0160AKE23

        Disconnect the fuel tube.

      3. A01605IE01

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

        SST
        09268-31012   ( 09268-41500, 90467-13001, 95336-08070 )

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

      5. A015ZMSE02

        Install SST and tube to the fuel fuel injector assembly.

        SST
        09268-31012   ( 09268-41160, 09268-41300, 90467-13001 )
      6. A0163I4E02

        Put the fuel injector assembly into a graduated cylinder.

        CAUTION:

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

      7. Operate the fuel pump (turn the engine switch on (IG)).

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

        SST
        09842-30090
        Standard injection volume
        72.3 to 75.2 cm3 (4.4 to 4.6 cu in.) per 15 seconds
        Difference between each fuel injector assembly: 18 cm3 (1.1 cu in.) or less

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

    3. Check for leaks.


      1. A0162JZ

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

        Standard fuel drop
        1 drop or less in 24 minutes
