Temp gauge does not move. Earth sender wire & gauge reads max. Is this a gauge fault?

more likely its the temperature sender thars at fault

The Fiat Cinquecento
Fun While It Runs

hope u have more luck with this than i did, mine did exactly the same (1995 Cinq Sporting), getting a new sender unit should be a very easy job (around 8quid) but for some reason mine was 'different' and took ages for fiat to find the 'right' part.. and it still didnt work once i got it.

when you order the new sender unit, make sure its the one for the gauge not the ECU. ECU one is rather more pricey.


Cinq Sporting - and yes, its broom yellow!

Sounds like a sender problem, and its certainly easier to change.
