The short answer is, there's not a lot the shade tree mechanic can do with the electronic speedometer. Check the sending unit (rear of the transmission) for loose/damaged/dirty connections or wires. IF there's nothing obvious wrong (it ate a huge rock at some point,etc.) the next order of business will be to track it thru the wiring harness, looking for loose conections or a bad ground connection. There's about a jillion grounds woven into the harness. Check and tighten/clean them all, and you might get lucky. The biggy is the 'bulkhead connector'...most,if not all, the van's circuits go thru this octopus. It's usually securely clipped together...maybe it's come undone. My '87 has about 70 numbered circuits, and there's empty slots in the plug. Some circuits go thru it TO the fuse block AND back out. It can get confusing... If this sleuthing does not help, steel yourself for a long day and pull the dash apart, noting carefully where all the screws and clips live. It'll help when you go back together. I'm betting the answer will be a cracked/broken lead in the circuit board(s) that comprise the speedo cluster. Whatever you do, don't blow a gasket and start ripping things apart!!! That's an absolutely bullet-proof way to turn your van into 'spare parts! If you can't find an obvious cause, turn it over to a speedometer shop, detailing exactly what you looked at. . Mike Bell Sometimes it's just a fuse. The guage is lit up by fibre-optics. There are 2 light bulbs which burnt out on mine, and I could'nt see the numbers on the guage. I could see them when the sun shone directly on the guage. It's not hard to change, try that.
The speedometer is cable driven.
It is an electric speedo so it can be the speed sensor or in the speedo itself.
Need to figure out what's wrong with them, first.
It does not have a cable... It is electronic controlled. It has a sensor that is bolted in the drivers side of the transmission TAIL SHAFT that controlls the speedometer among other things.
It is probably a bad speed sensor. The speed sensor is located on the transmission and sends a signal to the speedometer. It acts like a speedometer cable only sending electronic pulses instead of turning like a cable does.
The best way is to buy a book on your model and see if you can do it. Then! Ask again on this sight for help when you feel confident that you know what your doing to repair the speedometer.
Back in 1991 I THINK that they still used a mechanical cable from the transmission to the speedometer. Only later did they change to electronic readout, but I'm not sure what year. It sounds like the speedo cable needs to be lubricated, possibly replaced.
The speedometer cable (which runs from the transmission to the dashboard) has snapped. This is a two-piece cable, and the one-piece cable in later Proteges will not work. I had the transmission replaced, and the cable could never be fit in properly. This is a mechanical speedometer, so you would have to change the entire speedometer part of the instrument panel to use a magnetic/electronic speedometer.
A 1991 dodge dynasty speedometer bouncing could be a sticking speedometer cable, or a bad drive gear. Check the cable first, and lubricate it to see if the problem stops.
The 1991 Geo speedometer cable is held in place with a swivel nut on each end of the cable. Turn the swivel nut to the left to remove the speedometer cable. Reverse the process to install the new speedometer cable.
Yes. The sensor on a 4 cly is on the back of the transmission on the passenger side near where the right drive shaft comes out. On a V6 it is on the other side.
you have to take out the intrument cluster and replaced the light bulbs that are inside the instrument cluster!...its really simple
This truck has an electronic speedometer. There is no speedometer drive cable, and therefore no drive gear to change to adjust the ratio. You can buy a box for around $170 that is inserted into the sensor circuit to adjust the speedometer readout. You can figure out how to reprogram the speedometer. Those are the options I have found. I am dealing with this issue on my girlfriend's son's S-10. Further research found this reference, which looks good to me. This weekend, I'm going to find the DRAC module and modify it according to the directions. The electronic module is very specific. Is it worth spending the money just to "calibrate" the speedometer. What are the symptoms of the uncalibrated speedometer. Wheel size change. Tire size change. It would be cheaper and faster to just have a dealer do it then you wouldn't have an expensive piece of useless equipment taking up space
Look up 1991 ford escorts manual transmission speedometer
1991 to 1995 Explorers have a conventional speedometer cable with a drive gear that is driven by the transmission on 2 wheel drive or the transfer case on 4 wheel drive. 1996 and newer have an electronic speedometer with a vehicle speed sensor that connects to the transmission or transfer case. 2000 and newer the VSS is combined with the rear axle sensor located on top of the differential.
probably mph or kph
Your speedometer is electronic and receives electric pulses from the speed sensor in the transaxle. First disconnect the battery and then locate the speed sensor in the transaxle. Remove it by loosening the 3 bolts while being extremely careful not to loosen the drive link. Replace in the opposite order and tighten bolts tightly.
If both speedometer and odometer do not work, usually the pulse signal are missing. E.g. the wiring coming from the rear differential where the sensor is located, can be deteriorated (broken or shorted). If speedometer only is inoperative, it is easiest to change the whole speedometer. To repair it, you need to be able to work on electronics, disassemble the speedometer unit, access the printed circuit board, and usually replace the leaking electrolytic capacitors on that board, as well as clean the circuit board of the electrolyte. Some other components may be broken also.
Yes , I BELIEVE the last year for a speedometer cable on a Ford Explorer was the 1995 model year so the 1991 Ford Ranger would definitely have a speedometer cable
The cable is manual drive on a 1991.It plugs directly in the back of the speedometer.
If the speedometer doesn't work at all then there could be two causes. The first thing is to check the needle it may be loose on the spindle, secondly there is a relay from the fuse box to the speedometer.
Disconnect everything and pull it out if it is like a manual 1991 ford escort
