  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

      *1
      		Component without harness connected
      (Fuel Injector Assembly)
      If the result is not as specified, replace the injector assembly.


  1. Check the injection volume.

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

    2. Install the O-ring onto the fuel injector assembly.

    3. Connect SST (adapter and hose) to the injector, and hold the injector and union with SST (clamp).

      		Vinyl Tube

    4. Install a vinyl tube onto the injector.

      CAUTION:
      Install a suitable vinyl tube onto the injector to prevent gasoline from splashing out.

    5. Put the injector into a graduated cylinder.

    6. Operate the fuel pump (RAV4_ACA30 RM000001IQZ02QX_01_0001.html ).



      7. Toyota Rav4. Aca30, 33, 38 Gsa33 Zsa30, 35.3Zr-Fae Fuel.Fuel System.Fuel Injector Inspection

    7. Connect SST (wire) to the injector and battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each injector 2 or 3 times.

      SST
      09842-30080
      Injection Volume:
      60 to 73 cc (3.7 to 4.5 cu. in.) per 15 seconds
      Difference between each injector:
      13 cc (0.8 cu. in.) or less
      NOTICE:
      Always do the switching at the battery side.
      If the injection volume is not as specified, replace the injector assembly.

  1. Inspect for fuel leak.

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

      Standard:
      1 drop or less every 12 minutes
