how does a dig speed odometer work and can they be fixed if they work part time sometimes it will say the speed but then stops at slower speed then I'm going some times it shows I'm going 1 mph no matter my speed can it be cleaned or do I need to replace it all together ??

Usually digital spedo problems are related to the speed pulse sending unit that's attached to the left front wheel.Half the time its a mechanical problem,the other half is a bad sending unit.
Your gonna have to pull it apart to visually and electrically test it.
The sensor has a rotating part driven from the spedo gearbox.It converts the rotations into pulses on one wire that is fed to the dash.Its converted to a MPH display.
