Vehicle Speed Sensors

A Vehicle Speed Sensor or VSS is a device that is used to measure the speed of a vehicle's axle or drive shaft rotation. It works by sending a series of pulsed signals to the engine's computer, speedometer, cruise control system etc.

Most Volkswagen / Audi products want to see a speed input ratio of 1Hz to 1km/h. In other words, at 100km/h (62mph) the input frequency for a speedometer or Engine Control Unit needs to be 100Hz.

If the VSS is going to be used to only for Cruise Control or Engine Management purposes 100% accurate speed isn't necessary as they need to know if you are moving and if so, are accelerating, decelerating or maintaining a constant speed. If you are looking for 100% accurate measurement for speedometer use then a signal calibration unit may be necessary as well.
