3MZ-FE ENGINE CONTROL SYSTEM: AIR FUEL RATIO SENSOR: INSTALLATION

INSTALLATION

1. INSTALL AIR FUEL RATIO SENSOR (for Bank 2)
(a) Temporarily tighten the air fuel ratio sensor to the exhaust manifold sub-assembly LH.
NOTE: Do not damage the air fuel ratio sensor.





(b) Using SST, fully tighten the air fuel ratio sensor to the exhaust manifold sub-assembly LH.
SST: 09224-00010
Torque: 44 Nm (449 kgf-cm, 33 ft-lbf)
Torque: 40 Nm (408 kgf-cm, 30 ft-lbf)
HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
- Make sure that SST and the wrench are connected in a straight line.

(c) Connect the air fuel ratio sensor connector and clamp.
