With such a magnetic sensor, the PCM uses this is a program to determine the speed output, correct?
On my 92 Bronco, there is a mechanical gear on the output, but there is an electronic speed indicator. There are constraints which I can change to correct the speed indicator to show correct through the PCM. Gear ratio, overall tire radius (mounted to vehicle), and something else, just can't remember now. I would think that all manu's have this capability, especially those with offroad capabilities as most first changes are tires.....
