Hella 230040391 ABS Wheel Speed Sensor

The Hella 230040391 is an OE-quality ABS wheel speed sensor (also known as a wheel speed sensor or ABS sensor) engineered to deliver accurate, reliable wheel speed data to your vehicle's critical safety systems. Designed as a direct 1:1 replacement for the original equipment sensor, this part installs without modification for a straightforward, professional-grade repair.

How It Works:

The wheel speed sensor monitors the rotational speed of each wheel and transmits that data to the ABS control unit. This information is used to prevent wheel lockup during hard braking and to support additional safety and driver-assist systems.

Key Features:

• OE-quality construction for fit, form, and function matching the original sensor
• Supports ABS (Anti-lock Braking System), TCS (Traction Control System), and ESP (Electronic Stability Program) operation
• Provides wheel speed data to engine, transmission, navigation, and chassis control systems
• Engineered for durability and long service life
• Direct plug-and-play replacement — no wiring modifications required
• Mounted directly above the impulse wheel connected to the wheel hub or drive shaft
