3UR-FE ENGINE CONTROL: AIR FUEL RATIO SENSOR: INSTALLATION

3UR-FE ENGINE CONTROL: AIR FUEL RATIO SENSOR: INSTALLATION

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






(a) Temporarily install the sensor to the exhaust pipe by hand.






(b) Using SST, tighten the sensor.
SST: 09224-00010
without SST - Torque: 44 Nm (449 kgf-cm, 32 ft-lbf)
with SST - Torque: 40 Nm (408 kgf-cm, 30 ft-lbf)
HINT:
- Use a torque wrench with a fulcrum length of 300 mm (11.8 in.). If using a torque wrench with a 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 Service Precautions.
- Make sure SST and the wrench are connected in a straight line.
