TCM Malfunction, And/Or Speedometer Sensor Malfunction.
The gears in the speedometer are stripped. If the odometer is working then you have input.
you can go to speedometer and out of speedometer
If the speedometer is not working but the odometer is, I would suspect the dash cluster is at fault. If both speedometer and odometer are not working I would suspect the speed sensor on the transmission is at fault.
If the speedometer and the odometer are not working, I would suspect the VSS (vehicle speed sensor). If only the speedometer is not working I would suspect the instrument cluster has problems.
If the speedometer continues to work - probably a broken gear etc. in speedometer head and probably will have to be replaced. If speedometer does not work -- probably a broken speedometer cable
why would a speedometer stop working on a Mazda
got the same exact problem.
Bad wheel speed sensor or cluster needs replaced
there is probably a sensor on the transmission that is either gone bad or become loose.
Probably a blown fuse. Check your manual to see if they share the same one.
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.
