2004 Expedition TPMS
 

We have a 2004 expedition that is always showing a tire pressure sensor fault. Used the auto enginuity to see if it would say which one but it doesnt. Anyone have any experience on how to fix it or troubleshoot it? It bugs the crap out of us. It only shoes up when the car is started. The tire light will flash a few times then it stays off.

Sounds like a tpms senser might have a bad battery or one or all of them need to be recalibrated......

There is an electronic tool to do the recalibrations.

You might want to bring it to a tire service center also...
