Hello all. My name is Ken and I just joined today. I have purchased a 2008 Yukon and really love it. It has the tire pressure light on and when I checked the tire pressures there was no reading for the right front tire. So naturally I assumed that that sensor had died and needed to be replaced. I had the tires rotated this morning, after they were rotated and they were reading again I still showed no reading on the right front. The tires were never dismounted and I watched them do the work. My question is where could the problem be if the same place is reading nothing but a different wheel is in the place it wouldn't read? Should I have it reset and see what happens? Any help will be greatly appreciated !
