From: Uncle_vito on 19 Jun 2010 07:38 If it is like my 2007 Highlander, they use the ABS system to monitor wheel speed. If the average speed of each wheel is not the same, they figure one tire is low on air and illuminate the yellow dash light.

If the valve stems are metal, it uses a sensor mounted at the end of the valve stem inside the wheel. -- Ray O (correct punctuation to reply)
