==new answer== I have a 1990 prelude and have recently experienced the same problem. It was the speed sensor. Honda's manuals said it was located in the speedo head assembly. But it was, in fact,located on the transmition! For the 1987 Prelude, a problem where speed and odometer readings are not appearing on the dash is likely caused by a problem with the speedometer cable. This assumes you have a mechanical system -- not electronic. If you have an electronic system, I am at a loss to help, aside from checking the fuse or OBD II. If you have a mechanical speedometer cable, the cable is connected to the back of the dashboard and pokes through the firewall in the engine compartment on the driver's side. The cable is probably black and about the size (diameter) of an ordinary pencil. From it's appearance in the engine compartment, it runs forward for about 16" and then goes across the engine to the passenger side and down to the top of the transmission. THIS IS PROBABLY WHERE THE PROBLEM IS. The cable connection has come loose. There's a (VERY) tiny clip that holds that connector onto the top of the tranny. If it is lost, buy a couple extras from the dealer. Push the cable down into the top of the transmission and while pulling the protective boot up, slip the clip around the cable connector notch. This clip will retain the cable in place. Lower the boot over the clip--you may need a hook-like device to pull the boot over the clip and connector. I found this somewhat difficult. However, when first inspecting the cable, MAYBE, just MAYBE, the clip is still attached to the end of the cable. So be careful when pulling the protective boot out of the way. Other possibilities, the cable is broken and a new one will have to be installed. I would guess a new cable costs $50 to $60. Another possibility is that the cable is disconnected at the dashboard. This probably would require accessing the back of the dashboard from underneath the driver's pedals, or worse, removing the dashboard itself. If the book says to do the latter, I'd seriously consider getting an estimate to have this done instead of doing it myself, but that's just me.

You more than likely have a loose ground wire, but it can also be a hot wire that is loose. Also check the fuse panel to see if the fuse is tight.
