Installation [04/2013 - 10/2017]: Procedure

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2017 Lexus IS 350, 2017 Lexus IS 300, 2016 Lexus IS 350, 2016 Lexus IS 300, and 2015 Lexus IS 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 [04/2013 - 10/2017]

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

        Without SST [Torque (N*m (kgf*cm, ft.*lbf))] 

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

        With SST [Reading of Torque wrench (N*m (kgf*cm, ft.*lbf))] 

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

        NOTE:

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

        HINT: 

        • This torque value is effective when SST is parallel to the torque wrench.
        • The "with SST" torque value is effective when using SST with a fulcrum length of 30 mm (1.18 in.).
        • The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 260 mm (10.2 in.).
        • If using a torque wrench with a different length, or connecting the torque wrench and SST at an angle, refer to the alternate torque values.

          Refer to PRECAUTION [04/2013 - 08/2015] , or refer to PRECAUTION [08/2015 - 10/2016] , or refer to PRECAUTION [10/2016 - 10/2017]

        *a Length of SST 30 mm (1.18 in.)
        *b Length of Torque Wrench 260 mm (10.2 in.)
      2. Connect the air fuel ratio sensor connector.
    2. For Bank 1:
      1. Using SST, install the air fuel ratio sensor to the exhaust manifold RH.
        • SST: 09224-00010 

        Without SST [Torque (N*m (kgf*cm, ft.*lbf))] 

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

        With SST [Reading of Torque wrench (N*m (kgf*cm, ft.*lbf))] 

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

        NOTE:

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

      2. Connect the 2 wire harness clamps to the wire harness bracket.
      3. Connect the air fuel ratio sensor connector.
  2. INSTALL BATTERY TRAY 
    1. Install the battery tray with the 3 bolts.

      Torque: 5.4 N*m (55 kgf*cm, 48 in.*lbf) 

    2. Connect the fuel pipe clamp to the battery tray.
  3. INSTALL POWER STEERING ECU ASSEMBLY 

    Refer to INSTALLATION [04/2013 - 09/2020]

  4. INSTALL V-BANK COVER SUB-ASSEMBLY 

    Refer to PROCEDURE - Step 105 [04/2013 - 08/2015] , or refer to PROCEDURE - Step 106 [08/2015 - 10/2016] , or refer to PROCEDURE - Step 106 [10/2016 - 10/2017]
