1. INSPECT FUEL INJECTOR ASSEMBLY


    A030449E01

  1. Measure the resistance between the injector terminals.

    Standard resistance:
    13.4 to 14.2 Ω at 20°C (68°F)

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



  1. Inspect the injector injection.

    CAUTION:
    Keep the injector away from sparks during the test.

    1. Install the fuel tube connector to SST (hose). Then connect the tube connector to the fuel pipe (vehicle side).

      SST
      09268-41048   (09268-41500, 90467-13001, 95336-08070)

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



      3. A100668E01

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

      SST
      09268-41048   (90467-13001, 09268-41110, 09268-41300)

    4. Put the injector into the graduated cylinder.

      CAUTION:
      Install a suitable vinyl tube onto the injector to contain gasoline spray.

    5. Operate the fuel pump.



      6. A075915E04

    6. 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.

    7. Operate the fuel pump.

    8. 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
      09842-30070  

      Injection volume:
      60 to 73 cm3 (3.7 to 4.5 cu in.) per 15 seconds

      Difference between each injector:
      13 cm3 (0.8 cu in.) or less

  1. Connect the intelligent tester to the DLC3.

  1. Connect the battery's negative (-) cable to the battery.

  1. Turn the engine switch on (IG), and push the intelligent tester main switch ON.

    NOTICE:
    Do not start the engine.

  1. Select the Active Test mode on the intelligent tester.

    HINT:
    Refer to the intelligent tester operator's manual for further details.

  1. If no intelligent tester is available, connect the battery's positive (+) and negative (-) leads to the fuel pump connector.



    A075915E05

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

    SST
    09842-30070  

    Injection volume:
    60 to 73 cm3 (3.7 to 4.5 cu in.) per 15 seconds

    Difference between each injector:
    13 cm3 (0.8 cu in.) or less

  1. Inspect the fuel leakage.

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

      SST
      09842-30070  

      Fuel drop:
      1 drop or less per 12 minutes

    2. Turn the engine switch off.

    3. Disconnect the cable from the negative (-) battery terminal.

    4. Remove SST.

      SST
      09842-30070  
      09268-41048  

    5. Disconnect the intelligent tester from the DLC3.

    6. Reconnect the fuel inlet hose (rear fuel pipe) to the fuel main tube.
