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 (See PRECAUTION ).



Make sure SST and the wrench are connected in a straight line.

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

a. Install the sensor to the exhaust pipe by hand.
