Installation

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

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

(a) 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 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) for 2WD:

Connect the air fuel ratio sensor connector.

2. INSTALL FRONT NO. 2 EXHAUST PIPE ASSEMBLY (for 4WD)

(a) Connect the front No. 2 exhaust pipe to the exhaust pipe support.

(b) Install a new gasket and the front No. 2 exhaust pipe to the exhaust manifold LH with 3 new nuts.

Torque : 54 Nm (554 kgf-cm, 40 ft-lbf)





(c) Connect the air fuel ratio sensor connector.

(d) Connect the heated oxygen sensor connector.

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