FUEL INJECTOR INSPECTION


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. A01NHTA

      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.

    2. Check the operation.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near a naked flame.

        *1 SST (Hose)
        *2 Fuel Pipe
        *3 SST (Clip)
        *4 SST (Fuel Tube Connector)
        *5 Retainer
        *6 O-ring

        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 a new O-ring onto the fuel injector assembly.

        *1 SST (Hose)
        *2 SST (Clip)
        *3 SST (Adapter)
        *4 O-ring
        *5 SST (Clamp)
        *6 Vinyl Tube

        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 Click here.

      6. A01NFHXE15

        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
        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive (+) terminal - Ground terminal Per 15 seconds 85 to 102 cc (5.2 to 6.2 cu.in.)
        Difference between each injector
        17 cc (1.0 cu.in.) or less

        Note

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

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

    3. A01NFXV

      Check for leaks.


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

        Standard fuel drop
        1 drop or less every 29 minutes
