Here | mrbaer could be right, cell phone chargers left plugged in can cause problems with TPMS, Air Bags, etc. However read your door sticker for correct pressure, if it had LT tires from factory and someone put P tires on and you bought the truck and didn't know, well you need to run higher PSI. I get people tell me my light is always on and I checked the tires. Well 3/4 tons with LT tires are like 60 psi ft's, and 80 psi rears. So look, otherwise probably bad sensor and you need to relearn to determine which one. | |
