Strange speedo problem

Can someone please help? I have a 2000 1.8Z, done 70,000 miles and a strange problem has recently arisen. Driving along at any speed,suddenly the speedo
needle drops to zero, the radio volume diminishes and there is a slight loss of power. This lasts only a few seconds then all is restored to normal. The problem may not recurr then for either a few minutes or a few days but what worries is that its not going to get any better. Please help. Thanks. Tony Anderson.

Sounds like a faulty Speedo sensor.

Google in this group for VSS or vehicle speed sensor. It's a well documented problem.
Bottom line if in the UK - about 24UKP and a fiddly 30 minute job, or 100UKP for a dealer to do it.
Replacement sensors are allegedly better.

A) sounds like it could be a vss. B) if there is any other electrical items acting strange it could be a temp. loss of voltage. eg. see if the inside light dims or goes out at the same time. If so it could be a dirty ground cable under the air cleaner. try moving the cable to the vertical inner fender just ahead of the black bracket in front of the air cleaner. There is a hole w/ a slot for it but clean the paint off lst and cover w/ grease ot weatherproof it.
