  Q: How to remove the TPMS Sensor and Transmitter on Toyota Sienna?

  A:

  The Tire Pressure Warning Valve and Transmitter can be removed by taking off both the front and rear wheels then. The tire needs a pressure release by removing its valve core and cap followed by taking out the nut and washer attached to the tire pressure warning valve and transmitter so that it can fall inside the tire. Save all the removed valve core beside the removed nut and washer as well as the cap for future use. The process of dropping the valve and transmitter into the tire should be followed by beading removal through the tire remover shoe while guarding the valve and transmitter from interference with the tire bead. Proceed with standard bead removal technique on the tire upper side before extracting the tire pressure warning valve and transmitter which requires bead removal also on the lower side using the same method. The replacement of tire pressure warning valve and transmitter requires using brand new grommets and washers.

  Q: How to install the TPMS Sensor and transmitter on Toyota Sienna?

  A:

  The tire pressure warning valve and transmitter installation takes place from inside the rim through its valve installation hole while maintaining accuracy of the printed side. The valve along with transmitter should be inspected for destructive or abnormal features and their inner grommet should be free from all foreign matter surrounding the rim hole. The valve and transmitter become subject to damage while operating at high speeds due to improper installation in an upside-down position. Identification number recording should occur ahead of installation for brand-new valve and transmitter devices since their ID registration will need post-installation ECU input. Screw the nut onto the rim side while tightening to 4.0 Nm (41 kgf-cm, 35 in-lbf). Additional rounding of the nut should stop after reaching this torque value. Foreign matter on the washer and nut should be checked before replacing the valve and transmitter where new grommet washer and nut are needed. Check the entire rim hole with its components for the presence of oil and lubricant or water because such contaminants can lead to improper assembly. Technical staff should mount the wheel disc on the mounting machine while positioning the main body of the valve and transmitter in specific shaded areas that prevent device interference with installation. Before mounting the tire bead place the tool to ensure both the valve and transmitter remain free of contact with the tire bead. The valve nut requires tightening to 4.0 Nm (41 kgf-cm, 35 in-lbf) torque after inflating the tire while checking for soapy bubble air leaks. The installer must torque the front wheel to 103 Nm (1050 kgf-cm, 76 ft-lbf) and repeat that torque for the rear wheel installation. The inspection of tires must include recording the transmitter ID along with the necessary checks for the tire pressure warning system.
