If the odometer is not working while the speedometer functions in a Mazda B2500, the issue may be related to a faulty gear or drive mechanism within the speedometer assembly. Typically, the speedometer uses a cable or electronic signal from the vehicle's speed sensor, which can still operate even if the odometer's internal gears are malfunctioning. Another possibility could be a problem with the vehicle's instrument cluster itself. A thorough inspection of these components is recommended to identify the exact cause.
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 Mazda tachometer and the speedometer have separate cables. The tachometer cable probably does not work properly. Change the tachometer cable.

The oxygen sensor on a b2500 Mazda is located in the exhaust. It is under the truck about even with the transmission.
I replaced one on my 2000 Mazda b2500. it's located on top of the differential. You un hook the one wire harness, remove one bolt and pry it out with a screw driver. It's not in there too tight, comes out pretty easy. It fixed my speedometer, ABS light and check engine light. I had to use a mirror fixed above the differential and a flash light to see what I was working on. Or you can just feel for it. You can get the part from autowarehouse.com for about $18, great place for parts. Now mine is a 2000 yr. I don't know if the 1999 would be the same or not. Good luck. By the way, dose anyone know the difficulty factor on changing the spark plugs on this 2000 Mazda b2500 4 cylinder engine? It doesn't look like fun to me.

Speed sensor located on top of rear axel dead center on my 99 B2500. Kills both the cruise and the speedomoter. Easy fix. I want to add to all 1994 and modern Mazda B series mini trucks that all this trucks are really Ford, all this info can be found in all the ford ranger books as well here in this forums, I am a proud owner of numerous Mazda Trucks, I still own my first Mazda B2200 1991 SE-5, and my second Mazda B2300 1998 and the third one I still own a B4000 1999 non of them 4x4. from 1994 and UP the speedometer is electrical and the sensor is at the rear differential and some automatic on the tranny. Hope this helps all of you on finding this sensor, let me add this sensor is very important so the computer can control the fuel economy of the ride.........................................
