FUEL TEMPERATURE SENSOR INSTALLATION

Note


  • When replacing the fuel supply pump, common rail, cylinder block, cylinder head, cylinder head gasket or timing gear case, it is necessary to replace the fuel inlet pipe with a new one.

  • After removing the fuel inlet pipe, clean it with a brush and compressed air.


  1. INSTALL FUEL TEMPERATURE SENSOR

    Note


    • Before replacing the fuel temperature sensor, be sure to clean the surrounding area.

    • When replacing the fuel temperature sensor, make sure that your hands are clean and do not use gloves, etc.


    1. Install a new gasket to the fuel temperature sensor.

    2. A01BBNFE02

      Using SST, install the fuel temperature sensor.

      SST
      09922-10010
      Torque:
      without SST
      22 N*m  { 224 kgf*cm, 16 ft.*lbf }
      with SST
      15 N*m  { 154 kgf*cm, 11 ft.*lbf }

      Tech Tips


      • Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). When using a torque wrench with a fulcrum length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification Click here.

      • Make sure SST and the wrench are connected in a straight line.

  3. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

  4. BLEED AIR FROM FUEL SYSTEM


    1. A01BBOIE01

      Using the hand pump mounted on the fuel filter cap, bleed air from the fuel system. Continue pumping until the pump resistance increases.

      Note


      • Hand pump pumping speed: Max. 2 strokes/ sec.

      • The hand pump must be pushed with a full stroke during pumping.

      • When the fuel pressure at the supply pump inlet port reaches a saturated pressure, the hand pump resistance increases.

      • If pumping is interrupted during the air bleeding process, fuel in the fuel line may return to the fuel tank. Continue pumping until the hand pump resistance increases.

      • If the hand pump resistance does not increase despite consecutively pumping 200 times or more, there may be a fuel leak between the fuel tank and fuel filter, the hand pump may be malfunctioning, or the vehicle may have run out of fuel.

      • If air bleeding using the hand pump is incomplete, the common rail pressure does not rise to the pressure range necessary for normal use, and the engine cannot be started.

    2. Check if the engine starts.

      Note


      • Even if air bleeding using the hand pump has been completed, the starter may need to be cranked for 10 seconds or more to start the engine.

      • Do not crank the engine continuously for more than 20 seconds. The battery may be discharged.

      • Use a fully-charged battery.


      1. When the engine can be started, proceed to the next step.

      2. If the engine cannot be started, bleed air again using the hand pump until the hand pump resistance increases (refer to the procedures above). Then start the engine.

    3. Turn the ignition switch off.

    4. Connect the intelligent tester to the DLC3.

    5. Turn the ignition switch to ON and turn the intelligent tester on.

    6. Clear the DTCs.


    7. Start the engine.*1

    8. A01BERAE03

      Enter the following menus: Powertrain / Engine and ECT / Active Test / Test the Fuel Leak.*2

    9. Perform the following test 5 times with on/off intervals of 10 seconds: Active Test / Test the Fuel Leak.*3

    10. Allow the engine to idle for 3 minutes or more after performing the Active Test for the fifth time.

      A01BCPLE05

      Tech Tips

      When the Active Test "Test the Fuel Leak" is used to change the pump control mode, the actual fuel pressure inside the common rail drops below the target fuel pressure when the Active Test is off, but this is normal and does not indicate a pump malfunction.

    11. Enter the following menus: Powertrain / Engine and ECT / DTC.

    12. Read Current DTCs.

    13. Clear the DTCs.


      Tech Tips

      It is necessary to clear the DTCs as DTC P1604 or P1605 may be stored when air is bled from the fuel system after replacing or repairing fuel system parts.

    14. Repeat steps *1 to *3.

    15. Enter the following menus: Powertrain / Engine and ECT / DTC.

    16. Read Current DTCs.

      OK
      No DTCs are output.

  5. INSPECT FOR FUEL LEAK


    1. Perform the Active Test.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the ignition switch to ON.

      3. Turn the intelligent tester on.

      4. Enter the following menus: Powertrain / ECD / Active Test.

      5. Perform the Active Test.

        Intelligent Tester Display Test Part Control Range Diagnostic Notes
        Test the Fuel Leak Pressurize common rail interior and check for fuel leaks Stop/Start

        • Fuel pressure inside common rail increased to specified value and engine speed increased to 2000 rpm when Active Test is performed

        • Above conditions preserved while Active Test is being performed
