马自达6/奔腾B70 后左ABS轮速传感器 GJ6A-43-72YA 原厂质量

For Mazda6 or FAW Pentium B70: if the instrument cluster shows ABS warning during driving, or if braking pedal feels spongy and stopping distance increases during emergency braking, the rear left ABS wheel speed sensor has aged or failed and cannot accurately transmit wheel speed signals. The sensor monitors wheel speed and sends data to the ABS control unit to regulate braking force, preventing wheel lock and enhancing safety. OEM number GJ6A-43-72YA; fits Mazda6 and Pentium B70. Installation requires disconnecting the battery negative and ensuring the sensor-to-hub clearance is clean and free of debris to prevent interference or improper installation.
