      *a Fulcrum Length

      Using SST, install the air fuel ratio sensor.

      SST
      09224-00010
      Torque:
      without SST
      50 N*m  { 510 kgf*cm, 37 ft.*lbf }
      with SST
      45 N*m  { 463 kgf*cm, 33 ft.*lbf }

      Note

      If an air fuel ratio sensor has been struck or dropped, replace it.

      Tech Tips


      • Use a torque wrench with a fulcrum length of 300 mm (11.8 in.). When using a torque wrench with a fulcrum length that is not 300 mm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification.

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

      *1 Air Fuel Ratio Sensor Connector
      *2 Bracket
      *a 1.5 mm (0.0591 in.) or less

      Lower the air fuel ratio sensor connector to the position shown in the illustration and connect the air fuel ratio sensor connector.

    3. Attach the clamp.

  2. CONNECT SENSOR INSULATOR


    1. Connect the sensor insulator with the nut.

      Torque:
      8.0 N*m  { 82 kgf*cm, 71 in.*lbf }

  3. INSPECT FOR EXHAUST GAS LEAK

    If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.

  4. INSTALL NO. 1 ENGINE COVER

      Attach the 4 clips to install the No. 1 engine cover.

      Tech Tips

      When attaching the clips, press the protrusions on the top of the No. 1 engine cover at the clip installation points.
