0.823,0.813 0.479,0.26 true 0.729,2.781 0.969,2.99 0.24,0.208 10 false *a 2.042,1.458 2.271,1.656 0.229,0.198 10 true *b 0.125,0.167 0.469,0.354 0.344,0.188 10 true SST
*a Length of SST 30 mm (1.18 in.)
*b Length of Torque Wrench 260 mm (10.2 in.)


Using SST, install the heated oxygen sensor to the front exhaust pipe assembly (TWC: Front and Rear Catalyst).

SST
09224-00010  

Torque:
without SST [Torque (N*m (kgf*cm, ft.*lbf))] : 44 N*m (449 kgf*cm, 32 ft.*lbf)
with SST [Reading of Torque wrench (N*m (kgf*cm, ft.*lbf))] : 39 N*m (398 kgf*cm, 29 ft.*lbf)

NOTICE:

If the heated oxygen sensor has been struck or dropped, replace it.


HINT:
·

This torque value is effective when SST is parallel to the torque wrench.

·

The "with SST" torque value is effective when using SST with a fulcrum length of 30 mm (1.18 in.).

·

The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 260 mm (10.2 in.).

·

If using a torque wrench with a different length, or connecting the torque wrench and SST at an angle, refer to the alternate torque values.
