1UR-FE ENGINE CONTROL: HEATED OXYGEN SENSOR: INSTALLATION

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

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

(b) Using SST, tighten the heated oxygen 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)

* 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 Service Precautions.
* Make sure SST and the wrench are connected in a straight line.

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