Re: Tire Pressure Sensor Fault
When one of the 4 pressure sensors give a signal that the TP is low you get a fault. Which one? It makes you go searching and checking all the tires for low air pressure. Same if a sensor is at fault which sounds like what's happening. I don/t believe there's a test for the sensors but you can test them by letting out air pressure from one at a time and see if it functions. Just be sure you have a tank to refill them. It's that or have 4 new ones installed and the tire/wheel rebalanced.
