The wheel sensor is a contactless type and it detects the rotating speeds of a wheel. It comprises a permanent magnet and coil. When the gear pulsers attached to the rotatory parts of each wheel (front wheel: outboard joint of the driveshaft, rear: hub bearing unit) turn, the magnetic flux around the coil in the wheel sensor alternates, generating voltages with frequency in proportion to wheel rotating speed. These pulses are sent into the ABS control unit and the ABS control unit calculates the wheel speeds.
