If it is digital it is electronic. If it has a hand (like on a mechanical watch) it has a cable. in 1990 whether it is digital ar analog gauges there both driven by a electric speed sensor. gmjim In 1990 the full size Jimmys 4wd actually had both. (I am not sure about the 2wd.) Some were electric and some were mechanical. Even though your speedo has a hand like a watch it still may be electric. The easiest way to tell is to look under the hood for a cable going through the firewall and a cable attached to the transmission. If you don't see a cable then look on the tail section of the transmission. If you see an electric plug, that is the speed sensor so you have an electric speedo.

The 240sx does not use a speedometer cable. It is electronic. The VSS (vehicle speed sensor) is located on the transmission. It sends pulses.AnswerI removed my entire guage cluster and never saw a cable, it was all electronic. not sure if that's where the cable would be, but that's what i found, just three plugs coming out of the cluster.

To change the speedometer cable on a 1990 Toyota truck, disconnect the cable, feeding it through the grommet, then disconnect it from the transmission. The process can then be reversed with the new cable.

There isn't a speedometer cable. There is a speedometer sensor,where it is located I am still trying to find out. On the tranny or in the speedometer or somewhere else?

There may not be a cable, it may be electronic (as was the case with my 92). If so, there is a speed sensor on the driver's side of the transmission tailshaft.

The contacts between the speedometer head and the wiring connector need to be cleaned. If that does not work get a used speedometer. It fixed mine.

If the speedometer breaks, it effects the odometer. Check the speedometer cable it may be broken, even under the insulation.

You can get a speedometer cable for your 1990 Toyota pickup truck at most auto-parts stores. Many Toyota dealerships have auto part departments open to the public.

IF THE CABLE IS DAMAGED, THE HOUSING IS DAMAGED. ITS A COMMON PROBLEM. REPLACE WITH NEW PARTS

Start by removing the gauge cluster, unhook the speedometer cable from back of cluster. Pull speedo cable thru the firewall, follow it down to the transmission, and then unhook it. Install in reverse order of removal.

It is an electronic speedometer. the sensor is located on top of the transmission. When I looked into getting a new one for my 89 it was about $80 new.

definitly a part...either the odometer unit itself, a speedometer cable or just the gear that's in the transmission under the cable...I say this as I've never seen a digital speedometer on any topaz or tempo from 1990 a before

On my 1990 Integra RS the speed sensor is a part of the speedometer assembly. I got code 17 after repairing a dry/noisy speedometer cable. After putting the speedometer cable and instrument cluster back together, I test drove the car and found the speedometer wasn't turning because I didn't have the cable inserted all the way. After driving just around the block with the speedometer cable not connected, code 17 appeared.

There is no speedometer cable on a 1990 Chrysler New Yorker. The speedometer is electically driven by a speed sensor mounted on the transmission. often the contacts are just corroded and some electrical cleaner will fix it right up. Other times the sender will have to be replaced. They are available from major Auto Parts stores like NAPA, or from the dealer.

If the grinding sound seems to be coming from the speedometer and grinds faster as your speed increases, the likely cause is the speedometer cable. At least some 1990 Dodge trucks (mine) have electric speedometers Len

I doubt if it has a cable. I have a 1990 350 and it's electronic.a pulse modulator on trans & nothing but wires on instrument cluster. .

User Avatar

how do you change the speedo cable on a 99 goldwing 1500, and how do you lube the front end/ I need instructions, not parts

User Avatar

i have a 1990 Isuzu trooper as well and the speedometer and odometer also quit working, they both come off of a mechanical cable that is attached to the drive train. that cable breaks, and you lose both speed and odometer indications. they are extremely difficult to find, so if you do, write me back...

In general, there are two possibilities. 1, remove the entire speedometer cable and housing, replacing it with a new one. 2, if the cable housing is still intact you can get an inner cable and just feed that through. Some of the inner cable kits can be difficult to cut to length so you may need to put it in, check for length then pull the inner cable out and follow the instructions for cutting it to length.

It would probably be cheaper to replace the cable, check with your local auto wrecker. This used part should be very inexpensive, compared to repairing it.

There are two types of speed sensors and you can't tell until you look. One is electrical/magnetic (VSS) and one is a cable that goes directly into the instrument cluster. Here is my answer to How to replace the Speedometer Cable in a 1990 Toyota 4x4 Pickup 3.0 3VZE V6. To remove the cable you will need to unhook the e-brake assembly and seperate the speedometer cable from the e-brake at the firewall by the gas pedal. On end goes to rear of the instrument cluster and the other end attaches to a small gear at the rear of the transmission. The instrument cluster will need to be removed.

Answerreplace the speedometer cable. the problem will get worse, before it brakes. there is no cure but replacement My 1989 Ford had a gear on the transmission that had to be replaced, cable was okay. Easier than replacing cable if it is like a Ford.

it Goes from the Gauge Cluster. throught the firewall and connects down in the top passanger side of the tranny
