another brava speedo problem

[Anonymous]

hi all just got a 1996 brava 1.4 12v but the speedo is not giving the right speed it only shows about half the speed i am going also the fuel and temp guages were wrong so i replaced the instrument unit and it fixed the fuel and temp guages but the speedo is the same. i have orded a gearbox sender unit from fiat but fiat want 115 + vat to fit so i went to my local garage and they will fit it for 30 vat but the guy said it might be somthing to do with the gearbox. how likley is this?

I know the speedo is connected to the gearbox because when i had our gearbox replaced i noticed the speedo wasn't working, took it back to the garage who put it on the lift and the fixed it in about 3mins. Don't know why you'd be getting half speed readings though. Are the wheels the standard size? Maybe that would affect it, i dunno. Anyone else got any ideas?

My question is, if the speedo isn't working, how do you know you're doing twice the speed it shows ?!?!?!

i know the speed about half because on the motorway when its floored it shows 45-50 max

I suppose, after thinking about it, perhaps the gearbox isn't the correct type. Would that cause the speedo to misread?

Speedo problem resolution?

Hi There,

I've just picked up your original post on Speedo problems and don't know whether you'll get this as your post was months ago, but if you do did you get the low speedo reading problem sorted ?

I've got a late Bravo HGT and have an intermittent problem where the speedo occasionally goes from working fine to reading low by about 30% (worked out by calculating from rev counter and deduction from blistering past other cars on motorway). Turning the engine off and back on resets the fault and the speedo works fine until the next time when it recurs at some point in the future.

I don't suppose you made any progress on fixing your problem ?

Cheers,

Rob.

The speedo and all other clocks work fine
