Title: 3UR-FE ENGINE CONTROL: HEATED OXYGEN SENSOR: INSTALLATION (2008 Sequoia)

INSTALLATION

1. INSTALL HEATED OXYGEN SENSOR (for Bank 2 Sensor 2)

(a) Install the heated oxygen sensor to the front No. 2 exhaust pipe assembly by hand.

(b) Using SST, tighten the heated oxygen sensor.

SST: 09224-00010

  • without SST

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

  • with SST

Torque: 40 N·m (408 kgf·cm, 30 ft·lbf)

HINT:

  • Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). If using a torque wrench with a 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 INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION (2008 Sequoia) .
  • Make sure SST and the wrench are connected in a straight line.

(c) Connect the heated oxygen sensor connector and 2 clamps.
