1. INSPECT FUEL INJECTOR ASSEMBLY


    A154756E02

  1. Check the resistance.

    1. Measure the resistance according to the value(s) in the table below.
      Text in Illustration 
      *1
      		Ohmmeter

      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.



  1. Check the operation.

    CAUTION:
    Perform the inspection in a well-ventilated area.
    Do not perform the inspection near any open flames.

    4. Put the injector into a graduated cylinder.

      CAUTION:
      Install a suitable vinyl tube onto the injector assembly to prevent gasoline splashes.

    5. Operate the fuel pump (Click here).

      		Specified Condition
      Positive terminal - Ground terminal
      		Per 15 seconds
      		47 to 58 cm3 (2.9 to 3.5 cu in.)

      Difference between each injector:
      12 cm3 (0.7 cu in.) or less

      CAUTION:
      Always do the switching at the battery side.

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

  1. Check for leaks.

    1. In the condition above, disconnect the test probes of SST (wire) from the battery and check if the fuel leaks from the injector.

      Fuel Drop:
      1 drop or less every 12 minutes
