I need to change the speed sensor on my Fiesta Mk 6, I have a replacement but with no workshop manual can anyone tell me where exactly the VSS is located. I had a cursory look and it wasn't obvious, better still a photo would be great as a `picture paints a thousand words

For vehicles without ABS, you should find it under the battery tray, attached to the top of the gearbox.

How infuriating, I can't find the location of the VSS on my Fiesta 2002 mk6 and furthermore, I can't find anywhere on the internet to give step by step instructions on how to replace it. i intend to buy a haynes manual but living in Spain it will take time for it to arrive. Has anyone done this VSS replacement who would be willing to give me some tips? I don't want to start removing unnecessary things.

If fitted its on the gearbox above the driveshaft, VSS are only used on non ABS models.

thanks Dan, point taken. Will get a few things out of the way and see if I can see it, it isn't an ABS model. How would ABS mean that a VSS is not fitted?

I should have said transmission not gearbox as its really in the bell-housing/diff area (at the rear of course), removing the battery tray is the only option for access I think.

The VSS is held in place by a pin, once removed it should just pull out.

ABS models work out the speed from the ABS sensors so don't need a VSS.

not always sensor tsb says check resistence between pin 1 and 2. (1=volts feed 2=sig out 3=ground) should be 1.5 kohms 5%. sure ford released a pcm update for vss faults, regards steve
