FUEL INJECTOR INSPECTION


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. A01NL9W

      Check the resistance.


      1. Using an ohmmeter, 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 injector assembly.

    2. Check the operation.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near an open flame.

        (Wire)
        *a Connect

        Connect SST (wire) to the injector assembly 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
        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive (+) terminal - Ground terminal Per 15 seconds 85 to 102 cc (5.2 to 6.2 cu.in.)
        Difference between each injector
        17 cc (1.0 cu.in.) or less

        Note

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

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