Door open Warning Light comes on every time the brake panel is on

Anytime I hit a bump in the road and in ny there's tons my tire pressure sensor fault comes on and my mechanic said ford had a sensor issue and it costs $400 to fix. So I just leave it. If my car sits for a day without being driven it will say low tire pressure and all tires will be fine then I'll drive it and it goes off and eventually tire pressure sensor fault comes back on. But my guy said it's not worth fixing. You probably hit a sensor.
