比亚迪F3后轮ABS传感器 YDF3-4013100 原车适配

If your BYD F3 shows ABS warning light on, or wheels lock during emergency braking or brake pedal feel abnormal, the rear wheel ABS sensor may be aging/damaged, failing to transmit wheel speed signals accurately. Sensor monitors wheel speed and sends data to ABS control unit to modulate braking force for anti-lock during emergency stops. OEM YDF3-4013100; fits BYD F3 (original model F3-3630300). Installation: clean iron filings and oil residue from sensor mounting hole; ensure harness secured and not interfering with moving parts; otherwise signal may be abnormal or warning light re-illuminate.
