Hella 230040701 ABS Wheel Speed Sensor

The Hella 230040701 is an OE-quality ABS wheel speed sensor engineered for accurate, reliable wheel speed measurement. Hella is a globally recognized original equipment supplier, and this sensor is built to the same exacting standards as factory-installed components — making it a trusted choice for professional technicians and DIY mechanics alike.

How It Works:

The wheel speed sensor continuously monitors the rotational speed of the wheel and transmits that data to the ABS control module. This signal is critical for preventing wheel lockup during hard braking and is also shared with other vehicle safety and driver assistance systems including traction control (ASR), stability control, and transmission management.

Key Features:

• OE-equivalent construction for direct, 1-to-1 replacement
• Built to original equipment specifications for precise signal output
• Durable housing and wiring designed to withstand harsh underhood and wheel-well environments
• Includes dedicated connector for plug-and-play installation
• Supports ABS, ASR (Anti-Slip Regulation), and vehicle stability systems
• Manufactured by Hella — a trusted OE supplier to major global automakers

Hella's extensive OE expertise ensures that aftermarket replacements like the 230040701 deliver the same performance and reliability as the original factory sensor, helping restore proper ABS and stability system function.
