why is the Tire Pressure Monitor System keeps coming on. on 2004 Mazda RX-8

It keeps coming on when I'm driving. I took it to Good Year and I replaced all 4 tires, put nitrogen on all 4, got a wheel allignment. I drove it and it still comes on. Any ideas?

They most likely damaged a sensor.

check the tire pressure maybe incorrect, try checking it yourself.
