I have a 03 town and country, and the tire system says that it needs service soon, I brought it in to the dealer and they could not fix it, they were able to retrain all 4 sensors, what could be wrong? I statred having problems after new tire were installed by Sams club. ---

By “retrain all four sensors” do you mean they reinitialized the system? That would be a normal requirement when a new tire is installed if you have a system that uses the wheel speed sensors. Mine requires it even after doing a rotation. ---

We have the pressure sensors. You use a strong magnet to retrain all 4 sensors starting at the front drivers side. The horn will sound each time it is retrained. I think one might be bad.
