± SUSPENSION AND AXLETIRE PRESSURE MONITOR VALVE
SA±17
3013 Author: Date:
2005 SEQUOIA (RM1146U)

If installed in the reverse direction, the tire pressure
monitor valve may be damaged or fail to transmit sig-
nals when running at high speed.

If installing a new tire pressure monitor valve, write
down the ID number before installation.

It is necessary to registor an ID in the ECU after instal-
lation (See page DI±805).
(b) Install the washer on the tire pressure monitor valve from
the rim side and tighten with a nut.
Torque: 4.0 NVm (41 kgfVcm, 35 in.Vlbf)
NOTICE:

Check that there is no foreign matter on the washer
and nut.

If the tire pressure monitor valve is removed when the
tire is removed for replacement, check that there is no
damage or cuts, and no foreign matter such as mud,
dirt or sand attached to the grommet. Replace the
grommet with a new one if any of the defects men-
tioned above are found.

Check that there is no oil, water or lubricant around
the rim hole, tire pressure monitor valve, washer and
nut. Failing to do so may result in improper installa-
tion.
(c) After the tire is inflated, the valve nut may be loose. Re-
tighten the nut to the specified torque and then check for
air leaks with soapy water.
Torque: 4.0 NVm (41 kgfVcm, 35 in.Vlbf)
(d) Set the wheel disc to the mounting machine and install the
lower tire bead. Position the main body of the sensor as
in the shaded area shown in the illustration.
NOTICE:
If the sensor is positioned outside this area, it generates in-
terference with the tire bead, causing possible damage to
the sensor.
(e) Install the upper bead.
NOTICE:
Make sure that the tire bead and tool do not interfere with
the main body of the sensor and that the sensor is not
clamped by the bead.
5. INSTALL FRONT WHEEL
