If the odometer isn't working as well, it means the cable snapped. It runs from the passenger side of the transmission to either the speed sensor or behind the dash. Havent changed one in a few years, theyre not that expensive on eBay.
I had that same problem and I had to replace my dash cluster.
I assume it's working and you just want to check the calibration of the speedometer. I recommend you use a GPS to check it since those devices have a speed indicator included in their many features. If your speedometer is indicating zero when the car is moving, you likely need a new speedometer. If it's reading zero when the car is moving, try clapping the dash above the instrument to see if the speedometer moves off zero. If it does, then you 100% need a new one. If it doesn't, then you 90% need a new one because you have about a 10%chance that it's the car's speed sensor which might be in the transmission. Not a big deal ($) that, the bigger deal ($$$) would be the speedometer itself.

Zero is tricky and is best avoided. If you're stuck with it, the GCF of zero and any other number is the other number. The GCF of zero and zero is zero.

They have to see what is causing this problem. And they will try to fix it.
Look on your dash inside of your car. Next to your speedometer will be your tachometer. if it is on anything but zero, your engine is running.
try tracing the wiring if an electronic speedometer it might have broken by the trans.
Have it checked for codes, the code will tell you what to diagnose.
Drive on a freeway or highway where there's a speedometer check point. Set your odometer to zero, drive the exact speed limit (try to use cruise control), and after the speedometer check point is over (5 miles), you will be able to determine if your speedometer is working correctly based on the miles driven according to your odometer and the end of the checkpoint.
your car has a speed sensor located on the transmission replace that and problem is solved
How come my speed odometer just drops and wont work and if i pound on the dash sometimes it will come back..
