This problem has been going on for awhile, but I was getting a TPMS warning light, not low tire pressure, but Check Tire Pressure Monitoring System light. It is ALWAYS the front right, even after a tire rotation. This happens only after the tire pressure gets up to 50 PSI, after that, the light comes on. When it drops below that, I turn the truck off, and it goes away. I have gone through the re-learning, and also had Discount tire check the sensors and they are all ok. The only thing that is left is, I had the right front wheel bearing replaced... Is there something in the wheel bearing that is throwing this off?? It HAS to be the new wheel bearing since this hasn't come up until after it was replaced. Let me know if anyone has any suggestions
