Questions and answers with the ‘Car Doc’

Q. I have a 2015 Ford F-150 and the dash shows two of the tire pressure sensors have failed. How do I get the dash to stop flashing the yellow low tire pressure icon? All tires are at or above the recommended pressure. I do not want to replace the sensors yet. A. The light is flashing because the truck is no longer receiving pressure readings from the failed sensors. While it may be possible for someone with a Ford-capable scan tool to alter the programming, I would not recommend it. The cost of trying to disable the system is often similar to simply replacing the sensors with quality aftermarket units. Keep in mind that the tire pressure monitoring system is a federally mandated safety feature, and repair shops and dealers are prohibited from disabling it. The simplest solution is to replace the failed sensors. Q. John, I need your opinion about this. I purchased a 2025 Cadillac XT4 new about two years ago.
