Hello,

My wife's Multi (a 2001 Y Reg JTD 110 ELX) has an inoperative speedo. The rest of the instruments work OK. Just the speedo does not and it has stopped counting up the mileage as well.

I connected my laptop and the error code indicated an inoperative speed sensor. This was a reasonably cheap part to replace so I have done just that. The speedo still does not work.

I have also fitted my wife's instrument cluster into my Multi (2003 53 Reg JTD115 ELX) where it was fully operational. As a further check, I fitted my cluster into my wife's car where the same fault (inoperative speedo) was present.

So I have a fully working instrument cluster and a brand new speed sensor fitted. Does anyone have any suggestions as to why the sensor is not talking to the speedo? I cannot read the speed directly from the ECU on my laptop either.

Regards

Ian

Have you put a multi-meter across the sensor and speedo ends of the cable(s)? As you've got a functioning Multipla to compare it with, that might narrow it down to a defective wire.

I would try the new sensor in your fiat to make sure its not a dud or put yours which you know works in the other fiat and go from there.

check the plug that goes onto the sensor and also follow the wires back to where they join the loom and check for damage.

Did you find the problem?
