2. INSPECT HEATED OXYGEN SENSOR (for Bank 2
Sensor 2)
(a) Measure the resistance of the sensor.
Standard resistance
If the resistance is not as specified, replace the
sensor.
INSTALLATION
1. INSTALL HEATED OXYGEN SENSOR (for Bank 2
Sensor 2)
(a) Using SST, install the heated oxygen sensor to the
front exhaust pipe.
SST 09224-00010
Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf) for use
with SST
44 N*m (449 kgf*cm, 32 ft.*lbf) for use
without SST
HINT:
• Use a torque wrench with a fulcrum length of 30
cm (11.81 in.).
• Make sure that SST and a wrench are connected
in a straight line.
2. INSTALL FRONT EXHAUST PIPE ASSEMBLY
(a) Check the compression springs.
(1) Check the compression springs using vernier
calipers.
Specified length:
38.86 mm (1.5299 in.)
HINT:
If the result is not as specified, replace the
compression spring.
(b) Install the gasket.
(1) Install a new gasket by hand onto the front
exhaust pipe assembly.
(2) Using a plastic hammer and wooden block, tap
in the new gasket until its surface is flush with
the front exhaust pipe.
NOTICE:
• Be careful with the installation direction
of the gasket.
• Do not damage the gasket.
• Do not reuse the gasket.
