    1. A001WDHC01
      *a Torque Wrench Fulcrum Length

      Using SST, install the air fuel ratio sensor to the exhaust manifold.

      SST
      09224-00012
      Torque:
      Specified tightening torque
      44 N*m  { 449 kgf*cm, 32 ft.*lbf }

      Note

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

      Tech Tips


      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

      • When using SST (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 255 mm (10.0 in.)):

        39 N*m (398 kgf*cm, 29 ft.*lbf)

    2. Engage the 2 clamps.

    3. Connect the air fuel ratio sensor connector.

  2. INSTALL NO. 1 FRONT FLOOR HEAT INSULATOR


    1. Install the No. 1 front floor heat insulator to the vehicle with the 3 nuts.

      Torque:
      5.0 N*m  { 51 kgf*cm, 44 in.*lbf }
