What are the reasons for a faulty wheel speed sensor in the Magotan?
2 Answers
The damage to the Magotan's wheel speed sensor is caused by factors such as a dirty sensor head or damaged sensor wiring harness. The specific reasons are as follows: Dirty sensor head: A dirty sensor head or contamination by magnetic materials can lead to the failure of the wheel speed sensor. If the wheel speed sensor frequently malfunctions after driving through water, muddy roads, sandy areas, etc., it is likely just dirty and can be cleaned to resolve the issue. External force damaging the wheel speed sensor wiring harness: In models produced before 2011, the wheel speed sensor wiring harness did not have extra length reserved, which often resulted in the harness being pulled apart when the steering wheel was turned to its limit. By modifying the wheel speed sensor bracket to create extra length for the wiring harness, the issue can be resolved after replacement, preventing further damage.
As a veteran driver of the Magotan, I've personally experienced a faulty wheel speed sensor and summarized several main causes. The most common is physical damage, such as driving frequently on gravel roads or construction sites where the sensor gets hit by stones or scraped against the road surface, cracking the housing. Another issue is water infiltration—during rainy days or car washes, high-pressure water jets hitting the undercarriage can cause water to seep in, leading to short circuits. I once nearly had my ABS fail, which was quite dangerous. Additionally, aging or loose wiring can cause connectors to come undone or cables to break due to prolonged vibration. The internal components of the sensor itself can also wear out over time, eventually failing as the vehicle ages. Once the ABS system malfunctions, braking becomes unstable, so I recommend having technicians check the sensor's position during every maintenance session and keeping it clean and dry. If the ABS warning light on the dashboard comes on, don’t delay—visit a professional repair shop immediately to avoid more extensive and costly repairs. With proper maintenance, the sensor can last several more years.
