i Just bought a 06 flareside, the {(!) brake} on the bottom left corner was on when i test drove it. they told me they would it fixed before i bought it. so they did, they said they replaced a sensor. it passed inspection, and i left the lot with it. 1 hour later it came back on. i called them and they made an appointment at the local ford dealer. it was there over night and they claimed they replaced a different sensor or something. 6 hours after leaving the ford dealership it came back on. now it comes on and off at random times while driving. anyone have any ideas what could cause this?

 

the (!) is a called a TPMS light. if its on it 1 of 2 things. if its on solid then one of your tires is love on air (the threashold is about 3-4 psi above or below spec). if it comes on and blinks then one of your sensors is broke.
