I have a 2012 Ford Fusion SEL. Shortly after we had our winter tires put on in December 2017, the tire pressure sensor fault light came on. At that time, I was driving in snowy conditions. The next day, the weather cleared, and after a short drive the tire pressure sensor fault light went off. Next snowstorm, same thing happened. And then this past week, driving in snowy conditions, the same thing happened again.
All three times, it has happened in snowy conditions. And then, once the roads clear, after a short drive the light goes off.
The first time it happened, I called the Ford dealership (a 40-minute drive away) and described the sequence of events. I asked if I should bring the car in. They told me it wouldn’t do any good, because it’s unlikely the fault code would be stored, and they would need the code to diagnose the problem. My husband is puzzled as to why snowy conditions would cause this to happen. Any suggestions?
