• Q: How to install the TPMS Sensor and transmitter on 2008 Toyota 4Runner?

  A: Begin installation by inserting the new grommet provided with the valve and transmitter into the valve opening of the rim from its interior side while making sure the print surface remains visible. Reinstall the grommet even when it looks unaffected because improper installation can happen when rims and valve and washer sections remain free of oil and water and lubricating substances. Miscellaneous objects must be absent from the rim hole while checking for visible damage on the valve and transmitter. Also check that the interior grommet remains free of foreign substances. Inverted positioning of the valve and transmitter might lead to equipment damage in addition to compromised high-speed signal transmission. The ID number of each newly installed valve and transmitter needs documentation before ECU registration becomes necessary. The procedure requires a new washer and nut installation from inside the rim with a torque limit of 4.0 Nm (41 kgf-cm, 35 in-lbf), then verify the washer and nut are clean of foreign materials. A mounting machine should hold the wheel disc along with the lower tire bead installation and the valve and transmitter main body must be positioned inside shaded areas to avoid creating interference. Put in the upper bead while making sure it avoids the valve and transmitter before installing the valve core while inflating the tire. The valve nut requires tightening to its specified torque following inflation tests for air leaks by applying soapy water on the tire. Proceed to set the tire air pressure to its specified value while implementing the valve cap on both the valve and the transmitter. Apply 112 Nm of torque power for installing both the front wheels and rear wheels. You must check the tire after repairs while confirming that Data List shows the correct tire pressure and record the required transmitter ID.
