Hella 230040101 ABS Wheel Speed Sensor OE Replacement

The Hella 230040101 is an OE-quality ABS wheel speed sensor designed to deliver accurate, reliable wheel rotational data to your vehicle's anti-lock braking system and associated safety systems. Engineered to meet or exceed original equipment specifications, this sensor is a direct 1-to-1 replacement for the factory unit.

Key Features:

• Detects wheel rotational speed and transmits data to the ABS control unit for precise brake intervention
• Speed data is also shared with traction control (TCS), stability control (ESP), transmission, and navigation systems for comprehensive vehicle management
• Built to OEM specifications using durable materials engineered to withstand harsh underbody conditions, temperature extremes, and road debris
• Designed for straightforward installation as a direct OEM-equivalent replacement — no modifications required
• Manufactured by Hella, a globally trusted Tier 1 OE supplier to major automakers worldwide

Hella wheel speed sensors are passive inductive sensors that generate an alternating current signal as the tone ring (pulse wheel) rotates. This signal is used by the ABS module to detect impending wheel lockup and modulate braking force accordingly, helping maintain vehicle control during emergency stops. Proper sensor function also supports anti-slip regulation (ASR) and electronic stability programs.

As a direct OE-quality replacement, the Hella 230040101 restores full ABS, traction control, and stability system functionality — giving drivers confidence in their vehicle's safety systems.
