Possibly your speed sensor. It mounts on your transmission and sends electrical impulses to your speedometer and odometer. The old days a speedometer cable did it mechanically

Make sure your speedometer is set to MPH, not km/h. You can change this using the little display above the radio. Change the display units to "ENGLISH".
