Cadillac DTS Forum - 2006 through 2012 Discussion, tire monitor system 06 dts in Past Cadillac Vehicle Discussion; My front driver tire pressure monitor no longer reads and says "service tire monitor system" . Is this as simple ...
The sensor inside the tire goes bad by time. If the other ones work that means that one is broken you have to replace it. Go to a tire shop take of replace it with a regular valve. The sensor has a # on it with that # look for it on ebay or rockauto. I may have a part # in my car because I had to replace 2 of them on my dts I'm going post the part # later today.
This is the the part # for that sensor 15268606 if you do not want pay dealer price look for it on ebay like I did.
