If its just the speedo failing and the rev counter works ok, its likely to be the speed sensor which is on the gearbox. This will have to be removed as soon as possible to avoid engine damage! Expect to pay about £30-40 not £128 like some have paid from a Ford dealer.

The speed sensor as well as talking to the speedo to say how fast youre doing also talks to the fuel pump and adjusts the amount of fuel to send to the engine according to the speed your doing. So, if it thinks youre doing 0mph, it will supply a minimum amount of fuel and is likely to stall when slowing down. You might notice a lack of power whilst the speedo is failing as its starving the engine of fuel, causing it to run a lean mixture, which also burns hotter and could overheat and damage the engine.

hi
your speedo works via the wheel speed sensors and/or the engine speed sensor and is processed via the ecu. facias are far more complicated than older models and do fail requiring specialist repair. To actually replace would require reprogramming in most cases.
I suggest you get your Focus scanned and see what dtc codes come up....speak to the technician and see if they make sense.
You may have abad wiring plug connector or something silly.
Dont guess...it too expensive.
Cheers

Speedo will cut out when driving


Sounds like your "speed sensor" is failing. When it fails it will cause irregular shift patterns and engine idle speeds.

I had exactly the same problem on my 2001 Focus 1.8.

Solution: a new VSS was fitted (costs about £30) plus garage costs. It is a DIY job if you dont mind getting your hands a bit dirty and should only take 30mins to do.
