The FAE 78003 Wheel Speed Sensor is engineered to provide precise rotational speed information for each wheel. This critical data is used by your vehicle's Anti-lock Braking System (ABS), Electronic Stability Control (ESC), and traction control systems to maintain optimal performance and safety. Designed as a direct replacement for the original equipment sensor, the FAE 78003 guarantees compatibility and ease of installation. It is manufactured to meet or exceed original equipment specifications, ensuring reliable and long-lasting operation. Proper functioning of the wheel speed sensor is essential for preventing wheel lock-up during braking and maintaining vehicle stability during acceleration and cornering. A faulty sensor can lead to illuminated ABS warning lights and compromised vehicle dynamics.
