The main reason that a speedometer and odometer will stop is because the speed sensor, located on the back top area of the transmission, has gone faulty. The part can be had very easily at any auto parts store, or junkyard. The reason the check engine light is on is because the speed sensor signal goes thru the ECM (computer) for the car to run the different things. If the signal is intermitent, or interupted, the light is set, as well as the speedo and odometer not working.
Another reason is that the ECM it's self is bad, you can locate the ECM behind the glovebox and give it a few knocks while the car is running, if your engine responds by cutting out (even just a little) then replace it. they are around $110.
Since there is no speedo cable, it must be an electrical issue with a sensor.
Question
Why is there no speedometer cable? Does it have digital gauges?
The reason I ask, is, when I first got my 1986 Celebrity, the speedometer and odometer did not work. The previous owner had bought a new speed sensor, but had not had it put in yet. I installed it first thing. no luck. In checking the speedometer cable, I found it was broken, (the end of the cable at the tans-axle). After I replaced the speedometer cable, it worked fine.
Now, I cannot imaging gm did away with speedometer cables in the two years before the 1988 came out. I do have a 1990 S-15 with digital gauges, and I know it does not have a speedometer cable. But, the 1990 Sunbird I used to own, with analog gauges, did have one.
you can go to speedometer and out of speedometer
If the speedometer breaks, it effects the odometer. Check the speedometer cable it may be broken, even under the insulation.
The gauge has failed.
If the odometer stopped working and the speedometer and cruise control still work, you have a bad odometer. It is part of the speedometer assembly so the whole thing will have to be replaced.
check the fuse, the speedometer does not run off of a fuse
In my personal experience the speedometer stopped working because the mechanical drive cable broke.
The speedometer and odometer may stop working in a Nissan Pathfinder due to an electrical short. It may also need a new spark plug.
If both the speedometer and odometer stopped working it is probably the speed sensor in the transmission gone bad. If only the speedometer quit you may have to replace the dash cluster with a reconditioned unit.
the speedometer on my 97 toyota camary stopped working and the check engine light came on why
If the odometer has failed, does the speedometer still work? They are both driven by a cable which spins. If the speedometer is still working, than the odometer has jammed. Probably a dealer fix.
If your odometer/speedometer stopped working, then you must replace the "vehicle speed sensor" located on top of the differential if your have a manual transmission.
The odometer on a 96 Ford Explorer is tied into the speedometer. If the speedometer is working then there is a gear problem inside of the speedometer causing the odometer to not work.
