Inspection [11/2021 - ]: Procedure

WARNING: This page is about a different car, the 2024 Lexus IS 500, 2023 Lexus IS 500, and 2022 Lexus IS 500. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT PORT 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 port fuel injector assembly.

    2. Check the operation.
      WARNING:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near an open flame.

      1. Remove the EFI fuel pipe clamp from the fuel tube connector.

      2. Disconnect the No. 2 fuel tube sub-assembly from the fuel pipe.

        Refer to PRECAUTION [11/2021 - 09/2022] , or refer to PRECAUTION [09/2022 - ]

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

          3. 95336-08070
        NOTE:

        Ensure that 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.

      4. Apply a light coat of gasoline to a new O-ring. Then install the O-ring to the port fuel injector assembly.
      5. Connect SST (adapter) and SST (hose) to the port fuel injector assembly, and hold the port fuel injector assembly and union with SST (clamp).

          4. 95336-08070
      6. Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.

        • SST: 09268-31014 
          1. 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.

        HINT: 

        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 to the port fuel injector assembly.
        WARNING:

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

      9. Set the port fuel injector assembly into a graduated cylinder.
      10. Operate the fuel pump with filter assembly.

        Refer to PROCEDURE - Step 1

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

        *a SST (EFI Inspection Wire I)
        • SST: 09842-30090 

        Standard Injection Volume

        Tester Connection Condition Specified Condition
        Positive (+) terminal - Ground terminal Per 15 seconds 84 to 101 cc (5.1 to 6.2 cu. in.)

        Difference between Each Port Fuel Injector Assembly

        17 cc (1.0 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 port fuel injector assembly side.

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

    3. Check for leaks.
      1. Disconnect SST (EFI inspection wire I) from the battery and check for fuel leaks from the port fuel injector assembly.

        Standard Fuel Drop

        1 drop or less per 25 minutes

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

      2. Connect the No. 2 fuel tube sub-assembly.

        Refer to PRECAUTION [11/2021 - 09/2022] , or refer to PRECAUTION [09/2022 - ]

      3. Install the EFI fuel pipe clamp to the fuel tube connector.
      4. Check for fuel leaks.

        Refer to PROCEDURE - Step 1
