There is a speed sensor at each wheel. Each sensor can be tested for continuity using an ohm meter disconnect sensor at harness see if it has continuity, best test is spin the wheel and look at wave pattern on an oscilloscope but you can use a voltmeter ans see that each sensor puts out an AC voltage signal as you rotate the wheel (properly jack up and support the vehicle).
