P42.30-0221-06

L6/1 Left front wheel speed sensor

L6/2 Right front wheel speed sensor

ABS only

L6 Rear axle speed sensor

ETS, ASR, ESP only

L6/3 Left rear wheel speed sensor

L6/4 Right rear wheel speed sensor

Wheel speed sensor, location

The front wheelspeed sensors (L6/1 and L6/2) are mounted on the front steering knuckle assemblies.

ABS: The rear wheelspeed sensor (L6) is located on the differential assembly.

ETS, ASR, ESP: The rear wheelspeed sensors (L6/3 and L6/4) are mounted on the rear wheel carriers.

Wheel speed sensor, task

To supply the current wheel speed to the ABS, ETS, ASR or ESP control module (N47-7, N47-2, N47-1 or N47-5).

Wheel speed sensor, design

Inductive sensor: Coil with magnetic core installed at a defined distance from reluctor on the front wheel hub, the rear halfshafts or the drive pinion at the rear axle.

Wheel speed sensor, function

The magnetic field of the wheel speed sensor is intersected by the teeth of a rotor. This changes the magnetic field and the coil induces an AC voltage. The frequency of this alternating current, governed by the number of teeth on the reluctor, fluctuates to reflect variations in wheelspeed, is proportional to wheelspeed.
