FUEL INJECTOR INSPECTION


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. A01HYVL

      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 result is not as specified, replace the fuel injector assembly.

    2. Inspect the injector injection.

      CAUTION:

      Keep the injector away from sparks during the test.

      5. Install a vinyl tube onto the injector.

        CAUTION:

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

      6. Put the injector into the graduated cylinder.

      7. Operate the fuel pump.

        (Wire)
        *a Connect

        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
        09842-30080

        Note

        Always switch the voltage on and off at the battery side, not the injector side.

        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive terminal - Ground terminal Per 15 seconds 87 to 105 cc (5.3 to 6.4 cu.in.)
        Difference between each injector
        18 cc (1.1 cu.in.) or less

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

    3. Check for fuel drop.


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

        Standard fuel drop
        1 drop or less per 20 minutes

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