2UZ-FE ENGINE CONTROL SYSTEM: AIR FUEL RATIO SENSOR: INSTALLATION

INSTALLATION

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

(a) Using SST, install 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.). 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 Service Precautions.
- Make sure SST and wrench are connected in a straight line.

3. INSTALL FRONT EXHAUST PIPE ASSEMBLY
(a) Install a new gasket and the exhaust pipe to the exhaust manifold RH with 3 new nuts.
Torque: 54 Nm (551 kgf-cm, 40 ft-lbf)
(b) Install a new gasket and the exhaust pipe to the center exhaust pipe with the 2 bolts.
Torque: 48 Nm (489 kgf-cm, 35 ft-lbf)
(c) Connect the air fuel ratio sensor connector.
(d) Connect the heated oxygen sensor connector and 2 clamps.
4. INSTALL FRONT NO. 2 EXHAUST PIPE ASSEMBLY
(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 (551 kgf-cm, 40 ft-lbf)
(c) Install a new gasket and the front No. 2 exhaust pipe to the center exhaust pipe with the 2 bolts.
Torque: 48 Nm (489 kgf-cm, 35 ft-lbf)
(d) Connect the air fuel ratio sensor connector.
(e) Connect the heated oxygen sensor connector.
5. INSTALL FRONT NO. 2 EXHAUST PIPE ASSEMBLY (for Regular Cab Standard Deck)
(a) Install a new gasket and the front No. 2 exhaust pipe to the exhaust manifold LH with 3 new nuts.
