2009 Scion xB Parts Questions & Experts Answers

• Q: How to install the TPMS Sensor and transmitter on 2009 Scion xB?

  A: The installation of the tire pressure warning valve and transmitter should begin by putting it into the valve hole of the rim from its internal side with the printed surface exposed. Regular inspection of the valve along with transmitter should look for damage or deformities while cleaning away any foreign objects from around and within the rim hole as well as inner grommet. The signal transmission and operational integrity of the valve and transmitter will suffer when they are improperly installed in the wrong direction. Registration of the ID number requires documentation before new valve and transmitter installation because registration within the ECU needs to be completed afterward. Negative torque value 4.0 Nm (41 kgf-cm, 35 in-lbf) corresponds to the proper installation torque for the washer when rotating it from the rim side of the component. Do not over-tighten beyond the specified torque value. When installing the valve and transmitter avoid all foreign objects on the washer and nut while replacing the grommet even if not damaged and keep oil and water and lubricants away from all components including the rim hole valve washer and nut for proper installation. Place the wheel disc into the mounting machine before installing the lower tire bead and position the main body of the valve and transmitter inside the shaded area to avoid tire bead interference. During upper bead installation keep the tire bead and tool aways from the valve and transmitter positions. The tire pressure should be increased followed by a retightened valve nut at 4.0 Nm (41 kgf-cm, 35 in-lbf) torque value while inspecting for air leaks using soapy water. A torque of 103 Nm (1,050 kgf-cm, 76 ft-lbf) should be used to tighten both front and rear wheels. Check the tires while recording their transmitter ID. Conduct an inspection of the tire pressure warning system as the last step.
