Inspection [11/2016 - ]: Procedure

WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT 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 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. Disengage the 2 claws to remove the No. 2 fuel pipe clamp.

        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 the fuel tube connector and fuel pipe.

      5. Apply a light coat of gasoline to a new O-ring, and then install the O-ring to the fuel injector assembly.
      6. Connect SST (adapter) and SST (hose) to the fuel injector assembly, and hold the 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.

      8. Check that SST (clamp) and SST (adapter) cannot be easily separated.
      9. Install a vinyl tube to the fuel injector assembly.
        WARNING:

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

      10. Set the fuel injector assembly into a graduated cylinder.
      11. Operate the fuel pump.

        Refer to PROCEDURE - Step 1

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

        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 Fuel Injector Assembly

        14 cc (0.9 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 fuel injector assembly side.

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

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

        Standard Fuel Drop

        1 drop or less per 20 minutes

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

      2. Connect the fuel tube sub-assembly.

        Refer to PRECAUTION [11/2016 - ]

      3. Install the No. 1 fuel pipe clamp to the fuel tube connector.
      4. Fuel Pipe Clamp Type A:

        Engage the 2 claws to install the No. 2 fuel pipe clamp.

      5. Fuel Pipe Clamp Type B:

        Align the protrusions of the No. 2 fuel pipe clamp with the notches of the No. 1 fuel pipe clamp, and engage the 2 claws to install the No. 2 fuel pipe clamp.
