FAILURE

Speed sensor detects wheel speed and transmits
speed signal to the ABS module. ABS system uses
these signals to control each actuator.

When the signal wheel rotates, its wire will intersect
with the magnetic line of force of the magnet in the
speed sensor, therefore, an alternate current voltage
(AC) is produced. Because the voltage frequency
of the AC voltage is proportional to the rotational
speed of signal wheel, the speed of the wheel can
be detected.
