1UR-FE ENGINE CONTROL: AIR FUEL RATIO SENSOR: INSTALLATION

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

(a) Temporarily install the air fuel ratio sensor to the exhaust manifold RH by hand.

(b) Using SST, tighten the air fuel ratio 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.
