Inspection [12/2013 - ]: Procedure

WARNING: This page is about a different variant/trim than selected.
  1. INSPECT FUEL INJECTOR ASSEMBLY 
    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

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

      *a Component without harness connected
      (Fuel Injector Assembly)
    2. Inspect the fuel injector assembly injection.
      WARNING:

      Keep the fuel injector assembly away from sparks during the test.

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

          2. 09268-41700
          3. 95336-08070
      2. Apply a light coat of gasoline to a new O-ring. Then install the O-ring onto the fuel injector assembly.

        *c SST (Adapter)
        *d SST (Clamp)
        *e Vinyl Tube
      3. Connect SST (adapter) and SST (hose) to the fuel injector assembly, and hold the fuel injector assembly and union with SST (clamp).
        • SST: 09268-31014 
          1. 09268-41110

          1. 09268-41110
          2. 09268-41300
          3. 09268-41800
      5. Install a vinyl tube onto the fuel injector assembly.
        WARNING:

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

      6. Set the fuel injector assembly in a graduated cylinder.
      7. Operate the fuel pump.

        Refer to PROCEDURE - Step 1

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

        *a SST (Wire)
        *b Connect
        • SST: 09842-30080 
        NOTE:

        Always switch the voltage on and off at the battery side, not the fuel injector assembly side.

        Standard Injection Volume

        Battery Connection Condition Specified Condition
        Positive (+) battery terminal - Negative (-) battery terminal Per 15 seconds 88 to 106 cc (5.4 to 6.5 cu.in.)

        Difference between Each Fuel Injector Assembly

        18 cc (1.1 cu.in.) or less

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

    3. Check for fuel drop.
      1. In the condition above, disconnect SST (wire) from the battery and check for fuel drop from the fuel injector assembly.

        Standard Fuel Drop

        1 drop or less per 20 minutes

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