Fuel Injector: Inspection: Inspection

  1. INSPECT FUEL INJECTOR ASSEMBLY 
    1. 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.
      WARNING:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near a naked flame.

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

          • 09268-41800
      5. Set the injector assembly in a graduated cylinder.
        WARNING:

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

      6. Operate the fuel pump.
      7. 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 
        NOTE:

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

        Injection Volume

        Tester Connection Condition Specified Condition
        Positive terminal - Ground terminal Per 15 seconds 60 to 73 cc (3.7 to 4.5 cu.in.)

        Difference between each injector

        13 cc (0.8 cu.in.) or less

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

    3. Check for leaks.

      1. In the condition above, disconnect the test probes of SST (wire) from the battery and check the fuel leaks from the injector.

        Fuel drop

        1 drop or less every 12 minutes

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