first, set all 4 tire pressures to the pressure indicated on the sticker placed on the door jam of the drivers front door. it'll most likely require 32 psi.
if you notice that one tire is lower than the other 3 you'll need to make sure that tire doesn't have a leak.
if there are no leaks then set the ignition to 'ON' then, locate the black button on underside of the drivers lower dash panel
press and hold this button while watching the tire pressure light in your instrument cluster. keep holding the button down until the tire pressure light blinks 3 times.
FIN.
if all of the above does not work then you might have a defective sensor. it's also possible the place that did your tires may have damaged it.
