Hella 230040471 ABS Wheel Speed Sensor

The Hella 230040471 is a direct-fit OE-quality ABS wheel speed sensor (also known as a wheel speed sensor) engineered to deliver accurate, reliable wheel rotation data to your vehicle's critical safety systems. Manufactured by Hella — a globally recognized OEM supplier — this sensor is built to meet or exceed original equipment specifications for a precise, trouble-free installation.

How It Works:

The ABS wheel speed sensor monitors the rotational speed of each wheel and continuously transmits that data to the vehicle's ABS control unit. This information is the primary input for multiple safety and driver-assistance systems, including the Anti-lock Braking System (ABS), Traction Control System (TCS), Electronic Stability Program (ESP), and hill-start assist. When a wheel approaches lock-up under braking, the sensor's signal allows the ABS module to modulate braking force in real time, maintaining vehicle control and steering response.

Key Features:

• OE-quality construction engineered to match original equipment specifications
• Inductive passive sensor design — operates without an external power supply
• Composed of a permanent magnet, copper winding, protective housing, and integrated wiring harness connector
• Cable available straight or at a 90-degree angle with protective covering for durability
• Direct 1:1 replacement for simplified installation — no modification required
• Mounts directly above the pulse/tone wheel on the wheel hub or drive shaft
• Supports ABS, TCS, ESP, and other wheel-speed-dependent vehicle systems
• Manufactured by Hella, a trusted global OEM and aftermarket supplier

The Hella 230040471 ABS sensor restores proper function to your braking and stability systems, helping ensure safe, confident stopping performance. Its robust design and OEM-level quality make it the ideal choice for professional repair shops and DIY technicians alike.
