SENSOR
For M/T models:





The sensor unit consists of a gear-shaped sensor rotor and a sensor element. The element contains a bar magnet around which a coil is wound. The sensor is installed on the back side of the brake rotor. Sine-wave current is generated by the sensor as the wheel rotates. The frequency and voltage increase(s) as the rotating speed increases.

For A/T models:





The front sensor units consist of a gear-shaped sensor rotor and a sensor element. The element contains a magnet and IC. The front wheel sensors are installed on the front of the wheel knuckles. As the wheel rotates, the sensor generates a square-wave signal. The frequency increase as the wheel speed increase.
