My understanding is that each sensor has its own address. When they mount the tires they need to specify to the system which wheel position each sensor is placed in. On my Volt I got a low pressure reading on my left rear. I stopped and checked it and it seemed fine. As I went on it kept showing lowering pressure. I finally checked all the tires and it was the left front. Evidently when they rotated the tires they didn’t reassign the locations. -Steve
