  1. INSTALL AIR FUEL RATIO SENSOR 

    HINT: 

    Perform "Inspection After Repair" after replacing an air fuel ratio sensor.

    Refer to INITIALIZATION [09/2014 - 11/2017]

    1. for Bank 2:
      1. Using SST, install the air fuel ratio sensor to the exhaust manifold LH.
        • SST: 09224-00010 

        Specified tightening torque 

        Torque: 44 N.m (449 kgf/cm, 32 ft.lbf) 

        NOTE:

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

        HINT: 

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

          Refer to PRECAUTION [09/2014 - 11/2017]

        • When using SST (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 260 mm (10.2 in.)):

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