2011 Ford Focus Low Tire Pressure Fault

Hayley

About a week ago the Low Tire Pressure Fault light came on my 2011 Ford Focus. It was flashing on and off so I checked my tire pressure and it was all normal. As the days went on more lights started flickering on and off (open door, safety brake) and the AC would turn on and off as the Low Tire Pressure Fault came on. Took it into the Ford dealership and they ran a diagnostic and cleaned the wires. They said they tried to fix the problem but no promises on if they solved it. 3 days later (last night) the signs started flashing again. Anyone have this problem that could give me some advice on what to do next?

Thanks!
