AIR FUEL RATIO SENSOR INSTALLATION

CAUTION / NOTICE / HINT

Tech Tips

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


PROCEDURE


  1. INSTALL AIR FUEL RATIO SENSOR


    1. A000QJWE02
      Text in Illustration
      *a Fulcrum Length

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

      SST
      09224-00011
      Torque:
      without SST
      44 N*m  { 449 kgf*cm, 32 ft.*lbf }
      with SST
      40 N*m  { 408 kgf*cm, 30 ft.*lbf }

      Note

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

      Tech Tips


      • Use a torque wrench with a fulcrum length of 300 mm (11.8 in.). When using a torque wrench with a fulcrum length that is not 300 mm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification.

      • Make sure SST and the wrench are connected in a straight line.

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

      *1 Wire Harness Clamp Bracket
      *a Air Hole

      Install the wire harness clamp bracket to the air fuel ratio sensor and connect the clamp.

      Tech Tips

      Make sure that the wire harness clamp bracket does not cover the air holes.

    3. Connect the air fuel ratio sensor connector.
