FUEL INJECTOR(for Port Injection) INSPECTION

PROCEDURE


  1. INSPECT FUEL INJECTOR ASSEMBLY


    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

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

    2. Check the operation.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near an open flame.


      1. A01OEQK

        Remove the EFI fuel pipe clamp from the fuel pipe.

      2. Disconnect the fuel tube sub-assembly.

      3. A01OE8YC05
        *1 Fuel Pipe (Vehicle Side)
        *a SST (Fuel Tube Connector)
        *b SST (Hose)
        *c SST (Hose Band)

        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

        Ensure that the SST 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.

      4. Apply a light coat of gasoline to a new O-ring. Then install the O-ring onto the fuel injector assembly.

      5. A01OF3UC02
        *1 O-ring
        *a SST (Hose Band)
        *b SST (Adapter)
        *c SST (Clamp)
        *d Vinyl Tube

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

        SST
        09268-31014   ( 09268-41160, 09268-41300, 09268-41700, 95336-08070 )
      6. A01OE74C02
        *a Lock

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

        SST
        09268-31014   ( 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.

        Tech Tips

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

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

      8. Install a vinyl tube onto the fuel injector assembly.

        CAUTION:

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

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

      10. Operate the fuel pump with filter.

      11. A01OE8WC02
        *a SST (EFI Inspection Wire I)

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

        SST
        09842-30090
        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive (+) terminal - Ground terminal Per 15 seconds 53 to 63 cc (3.2 to 3.8 cu. in.)
        Difference between each fuel injector assembly
        10 cc (0.6 cu.in.) or less

        Note


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

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

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

    3. Check for leaks.


      1. Disconnect the tester probes of SST (EFI inspection wire I) from the battery and check for fuel leaks from the fuel injector assembly.

        Standard fuel drop
        1 drop or less every 14 minutes

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

      2. Connect the fuel tube sub-assembly.

      3. Install the EFI fuel pipe clamp to the fuel pipe.

      4. Check for fuel leaks.
