The TOPRAN 111 374 speed sensor is a crucial component for your vehicle's transmission system. It accurately measures the rotational speed of the transmission output shaft and sends this information to the vehicle's computer (ECU). This data is vital for various functions, including the Anti-lock Braking System (ABS), Electronic Stability Control (ESC), cruise control, and speedometer readings. A malfunctioning speed sensor can lead to inaccurate speedometer readings, ABS warning lights, or issues with other electronic systems. Manufactured by TOPRAN, this sensor is built to meet stringent quality standards, ensuring durability and consistent performance. It is designed as a direct replacement for the original part, facilitating a straightforward installation process.
