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. A0029DQC01
      *a Length of SST 30 mm (1.18 in.)
      *b Length of Torque Wrench 260 mm (10.2 in.)

      Using SST, install the air fuel ratio sensor to the exhaust manifold sub-assembly RH.

      SST
      09224-00010
      Torque:
      without SST [Torque (N*m (kgf*cm, ft.*lbf))]
      44 N*m  { 449 kgf*cm, 32 ft.*lbf }
      with SST [Reading of Torque wrench (N*m (kgf*cm, ft.*lbf))]
      39 N*m  { 398 kgf*cm, 29 ft.*lbf }

      Note

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

      Tech Tips


      • 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.
