    1. for LHD


      1. A002BW5C01
        *a Torque Wrench Fulcrum Length

        Using SST, install the air fuel ratio sensor to the exhaust manifold (TWC: Front Catalyst).

        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 180 mm (7.09 in.)):

          37.7 N*m (384 kgf*cm, 28 ft.*lbf)

      2. Engage the 3 wire harness clamps.

      3. Connect the air fuel ratio sensor connector.

    2. for RHD
