Inspection [11/2018 - ]: Procedure

WARNING: This page is about a different variant/trim than selected.
  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 No. 1 fuel pipe clamp from the fuel tube connector.

          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 the fuel tube connector and fuel pipe.

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

      7. Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.

        • SST: 09268-31015 
          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), detach the lock.

      8. Check that SST (clamp) and SST (adapter) cannot be easily separated.
      9. Set the port fuel injector assembly into a graduated cylinder.
      10. Connect the Techstream to the DLC3.
      11. Turn the power switch on (IG).
        NOTE:

        Do not start the engine.

      12. Turn the Techstream on.
      13. Enter the following menus: Powertrain / Engine / Active Test / Activate the Circuit Relay.

        Powertrain > Engine > Active Test 

        Tester Display
        Activate the Circuit Relay
      14. Connect SST (EFI inspection wire K) to the port fuel injector assembly and auxiliary 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 K)
        • SST: 09842-30110 

        Standard Injection Volume

        Tester Connection Condition Specified Condition
        Positive (+) auxiliary battery terminal - Negative (-) auxiliary 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 K) is securely connected.
        • Always switch the voltage on and off at the auxiliary battery side, not the port fuel injector assembly side.

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

      15. Turn the power switch off.
      16. Disconnect the Techstream from the DLC3.
    3. Check for leaks.
      1. Disconnect SST (EFI inspection wire K) from the auxiliary battery and check for fuel leaks from the port fuel injector assembly.

        Standard Fuel Drop

        1 drop or less per 20 minutes

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

      2. Connect the fuel tube sub-assembly.

        Refer to PRECAUTION [11/2018 - 02/2019] , or refer to PRECAUTION [02/2019 - 08/2020] , or refer to PRECAUTION [08/2020 - ]

      3. Install the No. 1 fuel pipe clamp to the fuel tube connector and close the cover of the No. 1 fuel pipe clamp.
      4. Check for fuel leaks.
