Car speedo issue.

[Levo-Lon]

Might be the speedo itself, breakers might have one.
Though if you can be bothered to remove the dials you may find the fault, lose connection as i had on a pug 309 gti.. Along with many many other green dirty connections, car was brilliant after cleaning loads of them in the engine bay.
Micro file and wd40 are your friends here.
Or its a sensor, if it was a cable drive which i doubt on a 2002 Japanese car it would not be intermittent.

I'm thinking a dodgy connection to the speedo dial itself.

Some come out easy, and they have a few large muti connectors, so worth a look, might be a you tube clip?

On a mark 4 Escort the speedo not working meant the gearbox mainshaft bearings were failing. About 50 miles further on, accompanied by grinding bag of spanner noises.

Well I'm hoping that doesn't happen.

You aren’t alone. Most vehicles must have dodgy speedos. Through our village, they drive through at 40mph which is twice as fast as the 20mph they think they are doing. And it happens everywhere else too.

Not so sure that's a speedo issue it's more than likely the nut behind the steering wheel at fault

Is the odometer & trip meter still knocking the miles up ?
Have any of the warning light's come on ? ie engine management light ?
Loads on google but all different models

Yes, the digital odo is racking up miles and the division mpg display is still working so I guess the sensor is fine.

No warning lights on either.

The speedo was also working again this morning but its failed twice in a many weeks now.

My analogue speedo, fuel gauge and temp are actually all digital. Wirth checking wires and if there is indeed a cable to the speedo.

AFAIK, faulty speedometer is a mot failure. Mileometer is not.

The speedometer isn't tested during the MOT but it's an offence to drive with one that isn't in good working order.

Looking at your answer i would also presume sensor is ok , so could just be a dry connection somewhere

How are they going to find it not working? I feel it may come as an advisory if noticed.
Section 6.7 MOT regulations.

Our old horsebox went through 3 ministry tests with a non working speedometer, it only failed the 4th as I had disconnected it from the gearbox to remove the broken inner & not screwed it back on whilst I waited for it to be delivered. The guy told me that because it was obvious that is wasn't connected therefore working he had to mark it down. It went back a week later after the other issue had been fixed, still not working but connected this time & passed.

I had a Rover metro that occasionally the speedo would start clicking. The cure was to rummage round behind the dash, disconnect cable, pop some grease on the end and reconnect.

Things were so much more simple.
