Where is the wheel speed sensor located on the Baojun 510?

The wheel speed sensor on the Baojun 510 is positioned on the inner side of the vehicle's tires. Working principle of the Baojun 510 wheel speed sensor: Most systems use inductive sensors to monitor vehicle speed. The ABS sensor interacts with a toothed ring that rotates synchronously with the wheel, generating a set of quasi-sinusoidal AC signals. The frequency and amplitude of these signals are related to wheel speed. This output signal is transmitted to the ABS electronic control unit, enabling real-time monitoring of wheel speed. Effects of a damaged wheel speed sensor on the Baojun 510: Not only can it cause excessive emissions, but it can also deteriorate engine performance, leading to symptoms such as stalling at idle, irregular engine operation, and reduced power output.
Last time I helped a friend fix the Baojun 510, the wheel speed sensor was located on the inner side of the wheel. There's one next to each of the four wheel bearings, and you can see a small black square with wires connected by removing the wheel hub cover. For the front wheels, it's behind the brake disc—just follow the ABS wiring harness with your fingers to locate it. For the rear wheels, you need to remove the brake drum, as it's hidden behind the axle hub. These sensors are particularly sensitive to impact—last time, a mechanic used an impact wrench to force it off and ended up destroying the sensor. Before checking, it's recommended to clean the mud from the wheel arch and disconnect the battery to avoid accidentally triggering the airbag system and causing trouble.
I've replaced the wheel speed sensor twice in three years with my 510. This part is clamped right next to the wheel hub center, close to the brake disc. For DIY replacement, you'll need a jack and socket set. The left front wheel position is particularly tricky - you have to remove the fender liner to access it. The OEM sensor harness is gray with a blue clip on the connector. Be cautious with aftermarket parts - I once had ABS false alarms on the highway after installing a cheap non-OEM sensor. It's best to clear the fault code with a diagnostic tool after replacement, otherwise that yellow exclamation mark on the dashboard can be really annoying.
The repair manual indicates that the wheel speed sensor labeled 510 is installed on the wheel hub bearing assembly. For the front wheels, it's located on the back of the steering knuckle, while for the rear wheels, it's integrated into the brake backing plate. During actual repairs, it's common to find sensor connectors contaminated with mud and water, leading to poor contact. Last week, a car owner reported the ABS warning light was on, and upon disassembly, it was discovered that a mouse had chewed on the left rear wheel sensor wiring, using it as a chew toy. When replacing, pay attention to the routing of the wiring harness; it must be secured according to the original corrugated tube position, otherwise, driving on rough roads can easily cause the insulation to wear through.
