I have a focus 1999 that has 49 k miles on the clock.recently I have noticed that the speedometer dies while I'm driving. The digital odometer also stops registering any distance travelled. It still displays just that it stops showing any new miles covered.
Then usually about 4 miles down the road both the speedometer and tachomter will start working as normal again. Anybody ever experience anything like this in their foci !?.

For the record I have changed my battery and alternator was overhauled though not replaced.
This was done for a different problem.
I had this speedo and odometer problem before and after doing the above.
Any ideas greatly appreciated.

Looks pretty straightforward in the manual. Never changed it myself (yet). It is on the transmission and held in with a pin. You have to remove the drivers side wheel and fenderwell liner and get to it from below. It is next to the right hand driveaxle, to the rear of the trans. Push back the pin to release the sensor and pop it out. Have a rag ready as you'll get some fluid. Make sure you get the "o" ring out too. Install as you removed it, but lube the "o" ring before installation. Really all it is is a magnet, so it should be pretty simple.

try putting vehicle in self diagnostic mode, put on mph if there's no reading when driving replace the speed sensor, i think it by on eof the axle shafts in the transmission.

the speed sensor feeds the ecm the ecm feeds the gauges.

My 2000 Focus was doing the exact same thing. I final bought a new vehical speed sensor for $52.00 last week and it works fine now. I was able to get to the VSS by removing the air filter housing and reaching back. You have to do it by feel this way but its not too hard. Trying to unlatch the connector in that position is a pain so, if you remove the pin that holds the VSS in and then pull the VSS out first you can unlatch the connector a lot easier.

thanks for all the feedback..., I will definitely try replacing the sensor myself.
I was worried initally that it might be a symptom of a bigger problem !

I had the same problem. I replaced the VSS yesterday and all seems ok now. After doing some experimenting, I found the easiest way to get at the VSS was to put the front on a set of ramps.

You can crawl under the car and get to the VSS. The only thing is you end up working on the sensor blind because of the position your hand/hands. Getting the sensor out was easy. Disconnecting the wiring harness was an other story. The clip holding the harness was a bear to un-snap while under the car.

I disconnected the MAP sensor and removed the air filter box cover and air filter. I fished the sensor and harness up. There's enough cable for you to work on it by the air box. I disconnected the harness and dropped it back down.

I made one last trip under the car to install the new sensor and connect the harness.

All told, it took about 30 minutes.

Unfortunately, it took the local dealer 2 weeks to get the sensor. Ford had a packaging problem and was shipping sensors under the wrong part number.

Hi all,

I'm new to this board and also have a problem with the speedo "dying" for a few minutes buts seems to reset if I turn the ignition on and off. The worrying thing is that this sympton is preceded by the engine cutting out and all the dash lights coming on-again the problem is cleared by turning the ignition on / off. I have had the car checked by a garage who say that the fault is not registering on the car. Can somebody give me any advise please. P.S. its a mk1 2001 1.8 Zetec

Ive recently started experiencing this problem on my 93k mi 2001 MTX ZX3. At random and usually inopportune times, my speedo needle drops to zero and sits there. Sometimes itll come back when i change gears, and sometimes it comes back whenever it feels like it. I had assumed speed sensor before checking posts, which confirmed my suspicions. I was looking on both RockAuto and Partstrain for the speed sensor and was presented with "Gear Driven" and "Non-Gear Driven" as options. How do I know which sensor I need to purchase? Any suggestions?

Thanks in advance!

Yea, thats what I had figured. Just confusing when you go to a parts website and put in your specific model, engine size and transmission and end up with the options for gear driven and non gear driven. I'll swing by the local Ford Parts counter and get some prices and make sure before I buy anything! Thanks![thumb]
