Hella 230040561 ABS Wheel Speed Sensor

The Hella 230040561 is a replacement ABS wheel speed sensor (also known as a wheel speed sensor or ABS sensor) engineered to restore proper function to your vehicle's anti-lock braking system. As a direct OE-quality replacement, it is designed for a precise, 1:1 fit in the original mounting location above the pulse/tone wheel.

How It Works:

The sensor continuously monitors the rotational speed of the wheel hub or drive shaft. That real-time data is transmitted to the ABS control unit, which uses it to prevent wheel lockup during braking. The same signal feeds additional vehicle safety and driver assistance systems including traction control (TCS), electronic stability programs (ESP), and hill-start assist.

Key Features:

• OE-Grade Quality: Manufactured by Hella, a Tier 1 OEM supplier to every major global automaker, ensuring factory-level fit and performance
• Accurate Speed Detection: Delivers a clean, reliable signal for precise ABS, TCS, and ESP operation
• Direct Replacement: Designed as a 1:1 OE replacement for straightforward installation with no modifications required
• Durable Construction: Built to withstand the harsh underbody environment including heat, moisture, and road debris
• Broad System Support: Supplies wheel speed data to ABS, traction control, electronic stability programs, transmission, navigation, and chassis control systems

Replacing a failed ABS wheel speed sensor with a genuine Hella unit helps eliminate common fault symptoms such as an illuminated ABS warning light, erratic speedometer behavior, and reduced braking effectiveness. Hella part number 230040561 provides a reliable, professional-grade solution.
