This FAE wheel speed sensor, part number 78118, is designed to provide critical data to your vehicle's Anti-lock Braking System (ABS) and Electronic Stability Program (ESP). By accurately measuring the rotational speed of the wheel, this sensor allows the vehicle's computer to detect wheel lock-up during braking or loss of traction during acceleration. This information is vital for the ABS to modulate brake pressure and for the ESP to intervene and help maintain vehicle control. Engineered with high-quality materials, the FAE 78118 sensor ensures reliable performance and durability in various driving conditions. Proper functioning of the wheel speed sensor is essential for the overall safety and performance of your vehicle's dynamic control systems.
