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?
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.
No, it uses a cable.
Check the side around the tailshaft.
It uses the VSS signal.
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.
Not lubricated
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
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
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.
