Installation

1. Insert the tire pressure monitor valve into the valve installation hole. Insert from the inside of the rim so

that the print surface can be seen. See Fig. 3. Check for the following:



Check that there is no visible deformation, damage or other abnormalities on the transmitter.



Check that there is no foreign matter on the inner grommet and around the rim hole.



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



If installing a new tire pressure monitor valve, write down the ID number before installation. See
Fig. 3. It is necessary to register an ID in the ECU after installation.

2. Install the washer on the tire pressure monitor valve from the rim side, and tighten the nut to 35 INCH

lbs. (4 N.m). See Fig. 6. Check for the following:



Ensure there is no foreign matter on the washer and nut.



If tire pressure monitor valve was removed, 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 these defects 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 installation.

3. Set the wheel disc to the mounting machine, and install the lower tire bead. Position the main body of the

sensor in the shaded area as shown in the illustration. See Fig. 7.

CAUTION: If the sensor is positioned outside this area, it generates interference

with the tire bead, causing possible damage to the sensor.

4. Making 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, install the upper bead.

5. After the tire is inflated, the valve nut may be loose. Retighten the nut to the specified torque, and then

check for air leaks with soapy water.

6. Install tire and wheel assembly.

7. When a new sensor is installed, the ID code will need to be registered. See TIRE PRESSURE SENSOR

REGISTRATION under RESET PROCEDURES.
