Hi, everyone. I've been following this website since I got my first Cougar (2002) in 2007. I'm on my third. Never had a need to post because all three have been problem free. I hope I can get a simple answer to this. I currently have a 2001Zn with 126+ miles. Runs great, but the speedometer stopped working. Since the bright yellow is very noticeable, I gotta get it fixed before I get nailed by a trooper. My mechanic thought it was the connection to the tranny ( manual), but the transmission guy says it's in the computer. Anybody have this issue? I really hope this isn't something that has to go to a dealer. The Ford dealer just had my husband's Flex for 5 weeks for computer issues. They don't work too fast. Can it even be fixed? I know some parts are impossible to get. Worst case scenario I'll have to use the speedometer app on my phone.
Thanks for any help.

Welcome.

Did the transmission mechanic actually pull the speed sensor out and look at it? It’s a mechanical sensor with a shaft (sometimes made out of plastic) that can break.

Its a very simple circuit, and not that hard to access.
What engine and transmission do you have?
Assuming you have a V6 auto, here's the circuit.

Is anything else on the cluster or anything else on the car out? Sometimes things are related that you don't realize.

Here's the circuit feeding the cluster

There's a troubleshooting chart starting on page 574 of the PDF here

I had an issue with the wiring on my speed sensor; the connection just got brittle and started to have connectivity problems. A new sensor solved all my issues.

Another possible issue is the speed gear inside the transmission that the sensor engages with - hopefully that's not the problem, as I think the trans has to be removed and opened up to access that gear, and they are impossible to find now.

I would use a GPS app on my phone in the meantime! Good luck.

Thanks for the input. No, the car's a manual and nothing else is out.
