Speedometer dose not move

[texasking254]

Ok I have a ford f250 7.3 psd and I been reading alot of info and just don't get it so maybe you guys can help. My speedometer won't move at all the truck shifts right and the miles are moveing. I took it to see if it is thoughing a code and it's not I cleaned the only senser I have on the rearend and I have two on top of the tranny and I also cleaned them but I don't know which one to replace the two on the tranny look just alike. So can you guy help me please

Check the fuse maybe I don't know I had one blow on my OBS one time. If it aint throwin the code more than likely it's not a sensor. Not sure what fuse it is though. Or could be the ABS module but I think that would throw a code too.

I thought when that went out the O/D light flashed too. Is your O/D light flashing? I know mine did when it went gunnybag.

Not always

How does the odometer know the truck is moving if that sensor is shot? (he says the "miles are moving".....)

Yea, but, if the odometer is "partially" working, wouldn't the speedo also be?

I donno, maybe not, one's digital and the other's analog so, they might be interpreted differently by the cluster......
