FUEL INJECTOR INSPECTION


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. A01CCJS

      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 a naked flame.

      5. Set the injector assembly in a graduated cylinder.

        CAUTION:

        Install a suitable vinyl tube onto the injector assembly to prevent gasoline from spraying.

        Difference between each injector
        16 cm3 (0.98 cu in.) or less

        Note

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

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

      Check for leaks.


      1. Disconnect the tester probes of SST (wire) from the battery and check for fuel leaks from the injector.
