For the past few weeks I've been getting false alarms from the TPMS. When I check the pressure it's always pretty close to the recommendations. I've told the stealer about it several times. They double check the pressure and explain how it works. But, later on that day or week, I get the same false alarms. I'll check the pressure again and it's never off by more than 1 or 2 psi. Could this have anything to do with that TPMS TSB numbered LTB00221. I've never used metal caps. But, I'm wondering if I can have them all replaced under this.
