I just purchased a 1989 nissan 240sx, but the electronic speedometer is stuck at zero. I have been told that it could be a fuse or the sensor. What do you guys recommend?

 

Probably the sensor got knocked outa place or sumthing

 

It could be a fuse but normally something else wouldn't work, like on my old corolla when a fuse blew, my tail lights went out and my interior lights also. It could be a bad connection with a ground wire. I'm not sure what year 240 it is, but it could even be a vehicle speed sensor. If it was a fuse it probably wouldn't even turn on. Im gonna say if its a car with a lot of miles on it, its probably a sensor or ground.
