-
Role in StabiliTrak Operation
Wheel speed sensors provide the StabiliTrak system with the data necessary to monitor wheel rotation and detect variances indicating potential skidding or loss of traction. The ECU compares the speed of each wheel, and if a significant difference is detected, the system intervenes by applying braking force to individual wheels and/or reducing engine power to help regain control. For example, if a vehicle is turning and one of the rear wheels begins to spin excessively, the StabiliTrak system may apply the brake to that wheel to stabilize the vehicle. A faulty sensor compromises this process.
-
Types of Wheel Speed Sensors
Two primary types of wheel speed sensors are commonly used: inductive sensors and Hall-effect sensors. Inductive sensors generate an alternating current (AC) signal as a toothed rotor rotates near the sensor. The frequency of the AC signal is proportional to the wheel speed. Hall-effect sensors, on the other hand, use a magnetic field and a semiconductor element to generate a digital signal representing wheel speed. Hall-effect sensors are generally more accurate at low speeds compared to inductive sensors. The specific type of sensor utilized can affect diagnostic procedures when troubleshooting StabiliTrak issues.
-
Common Failure Modes
