FUEL INJECTOR INSPECTION

PROCEDURE


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. Check the resistance.


      1. A01VGJW

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Standard Condition
        1 - 2 20°C (68°F) 11.6 to 12.4 Ω

        Tech Tips

        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. Do not perform the inspection near any flames.

        Text in Illustration
        *1 Hose
        *2 Clip
        *3 Fuel Tube Connector
        *4 Fuel Pipe
        *5 Retainer
        *6 O-ring

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

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

        Note

        SST (connector) seals the fuel tube connector and pipe with an O-ring. Ensure that there is no damage or foreign matter on the contact surface. Install the O-ring onto the fuel injector.

      2. A01VED8E03

        *1 O-ring
        *2 Vinyl tube
        *3 Clamp
        *4 Clip
        *5 Adapter

        Install the O-ring onto the fuel injector.

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

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

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

        Note

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

      5. Operate the fuel pump Click here.

      6. A01VIG7E03

        Connect SST (EFI inspection wire H) to the battery for 60 seconds, and then measure the injection volume with the graduated cylinder. Repeat 2 or 3 times and calculate the average.

        Injection Volume
        Tester Connection Condition Specified Condition
        Positive terminal - Ground terminal 1 minute 193 to 205 cm3 (11.8 to 12.5 cu in.)
        SST
        09842-30080
        Difference between injectors
        12 cm3 (0.7 cu in.) or less

        CAUTION:

        Always do the switching (voltage on/off) at the battery terminal.

        Tech Tips

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

    3. Check for leaks.


      1. A01VL5L

        In the condition above, disconnect SST (EFI inspection wire H) from the battery and check the fuel leakage from the injector.

        Fuel drop
        1 drop or less every 12 minutes

      2. Connect the fuel tube.
