Speedo on Nissan Micra

Ornithopter_al

My Daughter rang the other day to tell me that the speedo on her 2001 K11 Nissan Micra wasn't working properly it keeps flicking back to 0 while she is driving along.

Any clues as to what would cause this? TheHaynes manual I borrowed from the library says: models from 1998 onwards are fitted with an electronic speedometer, wired to the vehicle speed sensor attached to the speedometer drive pinion.

If I replaced the speed sensor would this be likely to cure the problem?

thanks in advance for any help/advice

Faulty dash or speedo head, Fault speed pickup sensor or a wiring fault between them.

Another issue is check the battery voltage. Fluctuations in voltage can play havoc with electronic speedo's.
