A tire pressure monitor fault can be concerning for drivers. It happens when the system that checks tire pressure stops working right. This warning means there might be a problem with one or more tire sensors.
Fixing a tire pressure monitor fault can cost between $0 and $500, depending on the cause. If it’s just low tire pressure, you can fix it for free by adding air. But if a sensor is broken, it may cost a few hundred dollars to replace it. Keeping tires at the right pressure is key for safety and fuel economy.
