别克昂科雷 ABS后轮传感器 10391044 安全系统组件

Buick Enclave rear ABS wheel speed sensor, OEM number 10391044, fits various years. Its core function is to monitor rear wheel speed in real time and transmit signals to the ABS control unit, ensuring proper operation of ABS during emergency braking. After installation, it effectively resolves ABS warning lights, unusual brake pedal vibration, or ABS activation failures. If braking feels like wheel lock on wet surfaces or ABS warning light persists, sensor aging or damage is likely, replacement required.
