Howdy y'all. I have a problem with my tire pressure sensor. It is blinking and hasn't turned off even though I have had the air checked in all of them even the spare. I took it to discount tire who said they couldn't even get a sensor reading. As in it is not connected??? Idk but it isn't bothering me to let it blink just didn't want to spend money I don't have to try and diagnose through a dealership. Any ideas?
