In older cars the speedometer comes in two components including speedometer cable as well as speedometer gauge. When speed increases the speedometer gauge is moved in circular movement. The drive gear for the speedometer transmits the circular motion of the cable into the gauge. This cable no longer is required in the most modern vehicles with fuel injection systems that are electronic.
They employ a speedometer sensor which changes the signal of circular motion of the speedometer drive gear to an electrical signal. The signal is then received by the computer of the engine and then relays this signal to the gauge of the speedometer.
The needle can move up or down based on the electrical signals received. The speedometer will give you an accurate measurement of time in millimetres per hour or miles per hour. The precision of the speedometer may depend on the diameter of the tire. It is also possible to search the internet to find more information on repair to the instrument cluster.
