I have been having problems with my TPMS in the tow vehicle going off at random times. After extensive research I have found that the problem is NOT with the TPMS but rather with the "cigarette" lighter cell phone charger. Seems the lower end cell phone chargers may emit RF interference that causes the TPMS module to not see one or more of the tire pressure monitors creating a "Tire Pressure Sensor Fault". I was skeptical but went ahead and removed the chargers and sure enough the problem has been cured.
It is my understanding that many tire shops and even stealerships (sic) are not aware of this issue and fix thereby charging customers for repeat visits without solving the problem. I cannot answer for other makes/models or years all I can say is try it to see if it works for you
