Fuel Injector Inspection

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.
   

Check the operation.

CAUTION:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near a naked flame.

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

   SST

   09268-31013(09268-41500,90467-13001,95336-08070)
   





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

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

   SST

   09268-31013(09268-41141,09268-41410,90467-13001,95336-08070)
   

4. Set the injector assembly in a graduated cylinder.
   

   CAUTION:

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

5. Operate the fuel pump (RAV4_ACA30 RM000001IQZ02HX_01_0001.html).
   





6. 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
   

   Injection volume:

   Tester Connection	Condition	Specified Condition
   Positive terminal - Ground terminal	Per 15 seconds	84 to 100 cm3 (5.1 to 6.0 cu in.)

   Difference between each injector:

   16 cm³ (0.96 cu in.) or less
   

   NOTICE:

   Always do the switching on the battery side.

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

Check the leakage.

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

   Fuel drop:

   1 drop or less every 16 minutes
