There could be a few things that can cause the Tire Pressure System Fault to come on. It could be one or more sensors, initiators which are the parts in the wheel well that signal the sensor or it can be the module. A Jag factory tool will be needed to read the stored faults in the module. We first need to make sure the initiators are in there proper place especially the front which are secured to the undertray at the bottom of each front wheel well. Sometimes they get dislodged and can cause this. Let me know.
