Fuel Injector - Inspection(2009/01 - )

1. Inspect fuel injector assembly

​

1. Measure the resistance between the injector terminals.

   Standard resistance:

   11.6 to 12.4 Ω at 20°C (68°F)
   

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

2. Inspect the injector injection volume.

   CAUTION:

   Keep the injector away from sparks during this test.

   
   
   2. Connect SST (fuel tube connector) to SST (hose), then connect them to the fuel pipe (vehicle side).

      SST

      09268-31012 (09268-41500, 90467-13001, 95336-08070)
      

   3. Install the O-ring to the fuel injector.

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

      SST

      09268-31012 (09268-41110, 09268-41300, 90467-13001)
      

   6. Put the injector into the graduated cylinder.

      CAUTION:

      Install a suitable vinyl tube onto the injector to contain gasoline spray.

   7. Operate the fuel pump.

   9. Connect SST (wire) to the injector 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:

      76 to 92 cm³ (4.6 to 5.6 cu in.) per 15 seconds
      

      Standard difference between each injector:

      16 cm³ (0.98 cu in.) or less
      

3. Inspect the fuel leakage.
   

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

      Standard fuel drop:

      1 drop or less per 12 minutes
      

   2. Turn the ignition switch off.

   3. Disconnect the cable from the negative (-) battery terminal.

   4. Remove the SST.

   5. Disconnect the intelligent tester from the DLC3.

   6. Reconnect the fuel inlet hose (rear fuel pipe) to the fuel main tube.
