Well, that depends. What car are you talking about? In some newer Fords, they now have the Hybrid Electronic Cluster (HEC). It works by reading the speed from the output shaft of the transmission via a speed sensor. As with any programming, it's as accurate as the person who programmed it.
In older Fords, there was a physical cable that went from the output shaft to the speedometer. It was as acurate as the person installing the little gear on the cable where the output shaft was at. Going up and down teeth on that little gear would move the speeometer needle up or down so many MPH (KM/H).
Hope that helps.
i thought they were based on how big the circumfrence is on youtr tires, then calculated how many times per minute the tire is rolling the complete circumfrence, and then it calculated that into mph

Both are basically right. My_porsche is talking about the theory and math used used, whereas the previous post is the actual mechanical application.
well put digital craft
im not owned d-quick, you get the same tire DIAMETER! and if you do get alot smaller wheels the speedo says you are going faster than you are, if you get bigger, ythen it says slower that it is

A turn of a small wheel goes a shorter distance than a large wheel, so a small wheel could turn 10 times and only go 10 metres but measure 20mph wheras a large wheel can turn 10 times and go 20 metres but will still only measure 20mph (just an example). Personally I'd just fit a GPS Speedo if i was that bothered about pinpoint accuracy, theyre as accurate as you can get nowadays.
sorry, my bad, i meant the other way around sorry guys

or you can use a calculator and a ruler.

Nah, I think what you initially said was correct.Originally Posted by my porsche
The Falcon uses the ABS sensors to determine speed..

You got it the right way around .. thats what i was trying to explainOriginally Posted by my porsche
