FUEL INJECTOR INSPECTION

PROCEDURE


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. Check the resistance.


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

    2. Inspect the fuel injector injection volume.

      CAUTION:

      Keep the fuel injector assembly away from sparks during the test.

        SST

        (Wire)
        *a Connect

        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
        09842-30080

        Note

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

        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive terminal - Ground terminal Per 15 seconds 47 to 58 cc (2.9 to 3.5 cu. in.)
        Difference between each fuel injector assembly
        11 cc (0.7 cu. in.) or less

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

    3. Inspect for leaks.


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

        Standard fuel drop
        1 drop or less per 12 minutes

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