AIR FUEL RATIO SENSOR INSTALLATION

PROCEDURE


  1. INSTALL AIR FUEL RATIO SENSOR (for Bank 1)

    Tech Tips

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



    1. B0075NFC01
      *A for LHD
      *B for RHD
      *a Torque Wrench Fulcrum Length

      Using SST, install the air fuel ratio sensor to the exhaust manifold sub-assembly RH (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 2 clamps and connect the air fuel ratio sensor connector.

    2. Engage the clamp and connect the air fuel ratio sensor connector.

  3. CONNECT NO. 3 ENGINE ROOM RELAY BLOCK


    1. Connect the No. 3 engine room relay block to the vehicle body with the bolt and nut.

      Torque:
      8.0 N*m  { 82 kgf*cm, 71 in.*lbf }

  4. INSTALL BATTERY TRAY (for LHD)


    1. Install the battery tray with the 2 bolts.

      Torque:
      5.4 N*m  { 55 kgf*cm, 48 in.*lbf }

  5. INSTALL BATTERY TRAY (for RHD)


    1. Install the battery tray with the 2 bolts.

      Torque:
      5.4 N*m  { 55 kgf*cm, 48 in.*lbf }
