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

  A:

  The first step for Tire Pressure Warning Valve and Transmitter extraction requires front and rear wheel removal. You must first release pressure from the tire by taking off its valve core and cap before disconnecting the wheel pressure warning valve and transmitter nut with its washer for complete valve entry into the tire. Recommends the retention of any removed tire valve core and plastic cap. You need to drop the valve and transmitter into the tire but you should do it after removing the tire bead through the shoe without allowing damage to the valve or transmitter from the tire bead. Continue by removing the bead from the upper side according to standard procedure and extract the tire pressure warning valve and transmitter before lowering the bead on the lower side through normal process. The entire set of grommet along with washer and nut should be removed whether or not the grommet shows signs of damage.

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

  A:

  The tire pressure warning valve and transmitter should be inserted through the inside of the rim valve installation hole with its printed surface facing outwards. Look for signs of deformation or damage or any abnormalities on the valve as well as the transmitter while also verifying that no foreign material exists on the inner grommet or around the rim hole. Combined installation of valve and transmitter in a reverse position could harm them or eliminate their signal transmission for quick vehicle movements. The ID number of new valves and transmitters requires recording because ECU registration becomes necessary after installation. After installing the washer along the rim side from the brake part tighten the nut to 4.0 Nm (41 kgf-cm, 35 in-lbf) torque while avoiding any post-specification tightening. Remove the grommet before valve and transmitter dismantling regardless of its condition. Wipe off any foreign material from both washer and nut before reinstalling them. The installation procedure requires the user to eliminate oil and all fluids from the rim hole as well as washer and nut locations to prevent installation defects. Lock the wheel disc into the mounting machine while carefully placing the main body of the valve and transmitter into the shaded area for interference prevention. The upper bead application should occur in a manner that prevents it from snagging the valve alongside the transmitter. Before exercising more pressure on the valve nut adjust it to 4.0 Nm torque (41 kgf-cm, 35 in-lbf) next check for air leaks with the help of soapy water. Maintenance professionals should install front wheels and rear wheels to achieve a torque measurement of 103 Nm (1,050 kgf-cm, 76 ft-lbf). Workers should inspect both tires then record the transmitter ID where required before conducting the tire pressure warning system check.
