  Q: How to install the TPMS Sensor and transmitter on Scion tC?

  A:

  Users should install the tire pressure warning valve and transmitter inside the valve installation hole from the inside rim position facing outward with its printed side detectable. The inner grommet should be checked for damage as well as foreign matter and deformation because poor installation could create high-speed problems which lead to signal transmission or tire damage. Before putting new tire pressure warning valves into use you must note down their ID numbers because they will need registration into the ECU after installation. Secure the washer from the rim side and use a torque wrench to reach 4.0 Nm (41 kgf-cm, 35 in-lbf) while leaving the installation complete when the torque target is achieved. The inspection must include a check for damage to the grommet or presence of foreign objects which will require replacement when defects exist. The installation process requires that all rim hole and its components stay free from oil or water and lubricant because they could result in improper fitment. Set the wheel disc on the mounting machine then install the lower tire bead while placing the main body of the tire pressure warning valve and transmitter within the shaded area as an interference prevention measure. When installing the upper bead users should check it does not compress the valve or transmitter. Use a torque wrench to set the valve nut at 4.0 Nm (41 kgf-cm, 35 in-lbf) after inflating the tire and then verify the leakproofness using soapy water. Mount the front along with rear wheels at a torque force of 103 Nm (1,050 kgf-cm or 76 ft-lbf). The conclusion of this process includes inspecting the tire followed by transmitter ID registration and verification of the tire pressure warning system operation.

  Q: How to remove the TPMS Sensor and Transmitter on Scion tC?

  A:

  The first step to remove the Tire Pressure Warning Valve and Transmitter is to take off both front and rear wheels. To drop the tire pressure warning valve and transmitter into the tire you must first remove the valve core and cap next release the air then untighten the nut with washer until they fall into the tire opening. The procedure recommends saving the spare valve core together with valve cap as well as nut and washer. When dropping the valve along with the transmitter into the tire you should use the shoe on the tire remover but stay cautious to prevent valve and transmitter damage from the tire bead interference. To complete the process remove the bead from the upper side using regular methods before extracting the tire pressure warning valve and transmitter out of the tire to finish opening the bead on the lower side with standard procedures. Check the grommet for damage before replacement in case any signs of fault become apparent.
