speedo dropping/ car jumping on 1.6- 2001 - Mac 74
Hi, noticed some threads with focus having very similar problems but with a different accompanying symptom.

My speedo drops to zero intermittantly. This is usually at (or just after) start up. The speedo dropping also coincides with the car jumping in low gear at low speeds although the jumping stops once i'm getting towards 30mph. When the speedo kicks back in the jumping stops.

No one else with the speedo dropping seems to have the problem with the jumping so not sure if the remedy is the same as others?

Is this something i should get sorted or is it ok to live with?

Thanks a lot.

Getting the speed sensor on the gearbox replaced would be a good place to start.

To quote from Haynes - " besides driving the speedometer, the speed sensor signal is used by the ECU as one of the parameters for fuel system-related calculations" I would recommend getting it changed. Cost me £22 for the part and £44 labour at my local garage. Have not had a problem since!
