hi as my speedo has stopped working along with the trip metre, im told by the garage that it will be the speed sencor, my question is are there two different secors, ie speed sencor and abs speed sencor or are they both the same thing????

You need to say what year/reg letter your car is so we can decide whether you have a gearbox driven speedo cable or an electronic one which takes its readings from the abs wheel sensors.

sorry to butt in on your post, but im looking at buying a 1995 / n-reg 850 t5 and the speedo isnt working, any idea on the speed sensor for this one,
thanks.

You will find the speed sensor behind one of the drive shafts underside of the gearbox off hand I forget which side but you cant miss it.

Volvo will charge you around £35-50 for the sensor. There is another sensor on the bell housing thats slightly cheaper

On late '95 ('96 model year) cars with this type of ABS unit:

the speedo is driven by an electronic signal from the ABS ECU.

Has your speedo stopped working becausde you pulled off one of the ABS fuses or for some other reasons?

That will be why it's not working, probably the first option is to do the resoldering job.
