My mother has a 2010 town and country mini van and the tpms light went on but when it showed the tire pressure it only shows tow dashes instead of actual numbers how do we fix this
You can try to reset them, but it sounds like the sensors have went away. On my GMC the TPMS sensors were still sending a signal but it was too low for the computer to read them so all I got was a blank screen when trying to read the pressures, had the TPMS sensors replaced and reprogrammed and everything works just fine. Most tire shops have the equipment that can read the sensors and tell you if they need replaced or if there is something wrong in the BCM.
