AIR FUEL RATIO SENSOR INSTALLATION

PROCEDURE

  1. INSTALL AIR FUEL RATIO SENSOR (for Bank 2 Sensor 1)

    1. Temporarily install the air fuel ratio sensor to the exhaust manifold RH by hand.

    2. A230385C02

      *1

      Fulcrum Length

      Using SST, tighten the air fuel ratio sensor.

      09224-00010

      without SST

      44 N*m

      449 kgf*cm

      32 ft.*lbf

      with SST

      40 N*m

      408 kgf*cm

      30 ft.*lbf

      Tip:

      • Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). When using a torque wrench with a fulcrum length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification (Click here).

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

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

    1. Temporarily install the air fuel ratio sensor to the exhaust manifold LH by hand.

      449 kgf*cm

      32 ft.*lbf

      with SST

      40 N*m

      408 kgf*cm

      30 ft.*lbf

      Tip:

      • Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). When using a torque wrench with a fulcrum length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification (Click here).

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