Does anyone know what pulse schedule the stock VSS puts out? 3 pulses per revolution of the ouput is fairly common, but I'm not sure what the Ford output is.
Thanks

The Vehicle Speed Sensor (VSS) is a variable reluctance sensor that generates a waveform with a frequency that is proportional to vehicle speed. When the vehicle is moving slowly, the sensor produces a low frequency signal. As the vehicle speed increases, the sensor produces a higher frequency signal. The processor uses this signal to control fuel injection, ignition timing and transmission/transaxle shift points.
