FUEL INJECTOR INSPECTION


  1. FUEL INJECTOR ASSEMBLY


    1. Inspect injector resistance.


      1. Using an ohmmeter, measure the resistance between the terminals.

        Resistance:
        11.6-12.4Ω at 20°C (68°F)

        Tech Tips

        If the resistance is not as specified, replace the injector.

    2. A01BCE6E01

      Inspect injector.

      Note

      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 spark or flame. Do not smoke.

      2. Remove the pressure regulator from the delivery pipe.

      3. Install the O-ring to the fuel inlet of the pressure regulator.

      4. A01BCIYE01

        Connect SST (hose) to the fuel inlet of the pressure regulator with another SST (union) and the 2 bolts.

        Torque:
        8.5 N*m  { 87 kgf*cm, 75 in.*lbf }

      5. Install the O-ring to the injector.

      6. A01BDPUE01

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

      7. Put the injector into a graduated cylinder.

        Tech Tips

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

      8. Operate the fuel pump

      9. A01BE8SE01

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

        SST
        09842-30080
        Result
        Volume Difference between each injector
        71 to 86ml 15ml or less

        Note

        Be sure to switch at the battery terminal side.

        Tech Tips

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

    3. Check for leakage.


      1. A01BDY6

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