It tells the ECu how fast the car is going, how much fuel to pump in, when to hang the idle.....
The VSS doesn't tell the EEC how much fuel to pump in. The EEC decides how much fuel to pump in based on the information from the VSS and the other sensors.

Ran a MK1 1.8 for 4 months with a knackered VSS and never noticed any difference what so ever.

The VSS lets the ECU know when the car is coming to a stand still, Low speed or idle, If the VSS is faulty it can cause a few problems, High idle speed and cutting out when coming to a stand still or even when you dip the clutch, If you suspect the VSS to be faulty unplug it and see if the car still cuts out at junctions etc
