Inspection [10/2015 - ]: Procedure

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2024 Lexus RC 300, 2023 Lexus RC 300, 2022 Lexus RC 300, 2021 Lexus RC 300, and 2020 Lexus RC 300. 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.

        (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 No. 2 fuel pipe clamp.

        NOTE:

        Do not reuse the No. 2 fuel pipe clamp.

      2. Disconnect the fuel tube sub-assembly.

        Refer to PRECAUTION [10/2015 - 09/2020] , or refer to PRECAUTION [09/2020 - ]

      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:

        Make sure 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 SST (fuel tube connector) and the fuel pipe (vehicle side).

      4. Apply a light coat of gasoline to a new O-ring, and 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).

        • 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.

        Refer to PROCEDURE - Step 1

      11. Connect SST (EFI inspection wire H) 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 H)
        • SST: 09842-30080 

        Standard Injection Volume

        Tester Connection Condition Specified Condition
        Positive (+) battery terminal - Negative (-) battery terminal Per 15 seconds 67 to 81 cc (4.1 to 4.9 cu. in.)

        Difference between Each Port Fuel Injector Assembly

        14 cc (0.9 cu. in.) or less

        NOTE:
        • Make sure that SST (EFI inspection wire H) 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 H) from the battery and check for fuel leaks from the port fuel injector assembly.

        Standard Fuel Drop

        1 drop or less per 11 minutes

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

      2. Connect the fuel tube sub-assembly.

        Refer to PRECAUTION [10/2015 - 09/2020] , or refer to PRECAUTION [09/2020 - ]

      3. Install a new No. 2 fuel pipe clamp.
      4. Check for fuel leaks.

        Refer to PROCEDURE - Step 1
