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 Figure 5). Check for the following: • Check that there is no visible deforma- tion, damage or other abnormalities on the tire pressure warning valve and transmitter. • Check that there is no foreign matter on the inner grommet and around the rim hole. • If the tire pressure warning valve and transmitter is installed upside down, it may be damaged by the tire bead when the tire is installed, or may fail to transmit signals when the vehicle is driven at high speeds. • If installing a new tire pressure warning valve and transmitter, write down the ID number before installation (see Figure 5). It is necessary to register the ID in the ECU aer installation. 2) Install the washer on the tire pressure monitor valve from the rim side, and tighten the nut to 35 in.-lbs. (4 N.m). See Figure 8. No further tightening is required once the nut is tightened to the specified torque. • Check that there is no foreign matter on the washer and nut. If the tire and tire pressure warning valve and transmitter have been removed, check that there is no damage or cuts visible, and no foreign matter, such as mud, dirt or sand, is attached to the grommet. Replace the grommet with a new one if any of the defects mentioned above are found. • Check that there is no oil, water or lubricant around the rim hole, tire pressure warning valve and transmitter, washer and nut. Failing to do so may result in improper installation. CAUTION: If the tire pressure warning valve and transmitter is positioned outside this area, it will interfere with the tire bead, and may cause the tire pressure warning valve and transmitter to be damaged. If the use of lubricant is required when install- ing the bead, do not apply the lubricant directly to the tire pressure warning valve and transmitter. 3) Put the wheel on 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 Figure 9). 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 and inflate the tire. 5) Aer 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 the tire and wheel assembly on the vehicle. 7) When a new sensor is installed, the ID code will need to be registered. See "Tire pressure sensor registration" under "Reset procedures." 8) After completing the operation, remove the valve core to rapidly release the air in the tire. Ensure the tire pressure warning light comes on. If the warning light does not come on, refer to the appropriate manufacturer service information. Re- inflate the tires. 9) If there is an air leakage, tighten the tire pressure monitor valve nut to 35 in.-lbs. (4 N.m), and push the valve core two to three times to remove any dirt attached to the valve core. If air continues to leak, replace the grommet, washer and nut. ■ Information for this column comes from the tire pressure monitoring systems data in ProDemand®, Mitchell 1's auto repair information software for domestic and import vehicles.
