FUEL INJECTOR INSPECTION

PROCEDURE


  1. FUEL INJECTOR ASSEMBLY


    1. Check the resistance.


      1. A0046Z2C06
        *a

        Component without harness connected

        (Fuel Injector Assembly)

        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.

    2. Check the operation.

      Note

      Perform the inspection in a well-ventilated area.


      1. A004AVUC31
        *1 Fuel Pipe (Vehicle Side)
        *a SST (Hose)
        *b SST (Hose Band)
        *c SST (Fuel Tube Connector)

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

        SST
        09268-31014   ( 09268-41500, 09268-41700, 95336-08070 )

        Note

        Make sure the SST (fuel tube connector) O-rings are not damaged and are free of foreign matter as they are used to seal the connections between the fuel tube connector and fuel pipe.

      2. A0047A8C02
        *1 O-ring
        *a SST (Hose)
        *b SST (Hose Band)
        *c SST (Adapter)
        *d SST (Clamp)
        *e Vinyl Tube

        Apply a light coat of gasoline to a new O-ring, and then install the O-ring to the fuel injector assembly.

      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   ( 09268-41141, 09268-41410, 09268-41700, 95336-08070 )

      4. Install a vinyl tube to the fuel injector assembly.

        Note

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

      5. A00496ZC21
        *a SST (Tie Band)
        *b SST (Adapter)
        *c SST (Clamp)

        Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.

        SST
        09268-31014   ( 09268-41141, 09268-41410, 09268-41800 )

        Note


        • As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.

        • Before using SST (tie band), make sure that there is no wear, damage or cracks. If there are any abnormalities, replace SST (tie band).

        Tech Tips

        When removing SST (tie band), disengage the lock.

      6. Check that SST (clamp) and SST (adapter) cannot be easily separated.

      7. Set the fuel injector assembly in a graduated cylinder.

      8. Operate the fuel pump.

      9. A0049Y1C25
        *a SST (EFI Inspection Wire H)
        *b Connect

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

        SST
        09842-30080
        Standard Injection Volume
        Battery Connection Condition Specified Condition
        Positive (+) battery terminal - Negative (-) battery terminal Per 15 seconds 47 to 57 cc (2.9 to 3.5 cu. in.)
        Difference between Each Fuel Injector Assembly
        10 cc (0.6 cu. in.) or less

        Note


        • Make sure that SST (EFI inspection wire H) is securely connected.

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

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

    3. Check for leaks.


      1. Disconnect SST (EFI inspection wire H) from the battery and check for fuel leaks from the fuel injector assembly.

        Standard Fuel Drop
        1 drop or less per 25 minutes

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

      2. Check for fuel leaks.
