Hello, my nissan 200sx coupe has a non functioning speedometer. It sometimes work but lately it hasnt worked at all. The gauge reads 0 miles per hour when the car is driving. I want to know if the speedometer is an electric or uses a cable and how to locate the cable or the electric box for it. Thank you

Have you check the fuse to see if the fuse for the gauges are bad, also there is a fuse box under the hood that may contain additional fuses if one is not located in the fuse compartment under the dash.
You have an electronic speedometer (no cable); get a 'donor' instrument cluster from another (Nissan) vehicle and replace the speedo. OR If your mechanically/electronically inclined, you can replace justs the 'guts', i.e., motor and circuit board (might as well replace the odometer motor while your at it) to keep your original mileage. There is a step-by-step guide on the web how to do it.
This is a common problem. All of these work from a printed circuit board. With vibration and age they will eventually get a short in the board. No one repairs them just replace the instrument cluster. Requires removing the front of the dash to remove it.
A large fuse is blown close to the battery...40 or 50 amp....took out the alternator and several other things...since you know the reverse jump took the fuse out you can jump the fuse with a large gauge wire (jumper wire) and get it going or ...get the right fuse from the local parts house. This fuse is obvious when you look at it, might have a small plastic cover
It is possible that this code can be caused by the speedometer head itself. The signal from the speed sensor is processed in the speedometer and then sent to the ECM. Check the two screws on the back of the speedometer to see if they are loose. If so retighten and drive to see if the check engine light comes back on. If they are tight, replace the speedometer assembly( I think you gave to purchase the entire meter assembly). If the light still comes on, which is unlikely, you will need to check the wire going to the ECM.
