Could be the speed sensor or another common problem with neons is broken solder points on the instrument cluster circuit board. To test it, see if your cruise control can keep you at speed. If so, it's the instrument cluster. If not could be the speed sensor. If you don't have cruise, then you may have to inspect the cluster for broken solder points.

Check the fuses. Sometimes you have to remove and reinstall them.
A sensor.
By replacing it.
because its a Dodge Neon
It doesn't have one. It uses a speed sensor and drives the speedometer electrically. If your speedometer isn't working, it could be the sensor or it could be broken solder points on the instrument cluster circuit board.

The speedometer is located on the instrument panel directly behind the steering wheel and is typically located in the center.
most of the newer spedos are magnet drive , you may want to check , but the usual fix is to replace it ! Good Luck !
Depends on what's wrong with the speedometer. Try re-soldering the contacts on the mainboard behind the instrument panel.
i would have to bet on the speed sensor
