Installation [09/2014 - 11/2017]: Procedure

WARNING: This page is about a different car, the 2017 Lexus RC 350, 2017 Lexus RC 300, 2016 Lexus RC 350, 2016 Lexus RC 300, and 2015 Lexus RC 350. However, it is still accessible from the selected car via links, so may be relevant.
  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)
