What are the symptoms of a faulty wheel speed sensor in the Mercedes GLS450?
1 Answers
The symptoms of a faulty wheel speed sensor in the Mercedes GLS450 include unstable engine idle, momentary stalling or engine shutdown when starting or decelerating to a stop, and reduced engine acceleration performance. Solutions for a faulty wheel speed sensor in the Mercedes GLS450 are as follows: External force damaging the wheel speed sensor wiring harness: In earlier models, particularly those before 2011, the wheel speed sensor wiring harness did not have extra length, which often led to the harness being pulled and damaged when the steering wheel was turned to its limit. This issue can be resolved by modifying the wheel speed sensor bracket to create additional length for the wiring harness, preventing future damage after replacement. False failure: Contamination of the sensor head or exposure to magnetic materials can cause the wheel speed sensor to malfunction. If the wheel speed sensor frequently fails after driving through water, mud, or sandy areas, it is likely due to dirt buildup and can be cleaned.
