Delphi SS20191 ABS Wheel Speed Sensor

The Delphi SS20191 ABS Wheel Speed Sensor is a precision-engineered component designed to monitor wheel speed and rotation, providing critical data to your vehicle's anti-lock braking system. This sensor plays a vital role in preventing wheel lockup during braking, helping maintain vehicle stability and control in challenging driving conditions.

Advanced Sensor Technology:

Delphi ABS sensors utilize advanced magneto-resistive or Hall effect technology that generates a digital square wave signal, changing only in frequency rather than amplitude. This design ensures improved accuracy, especially at lower speeds, and can detect wheel direction including forward, reverse, and stop conditions—essential for modern safety features like hill hold control and automatic parking assistance.

Key Features:

• Weather pack connectors with plated pins for superior corrosion resistance
• Rigorously tested to OE standards for reliability in all conditions
• Optimum signal stability for accurate wheel speed monitoring
• Direct-fit design matching OE mounting and connector specifications
• Like-for-like wire lengths for straightforward installation
• Durable construction designed to withstand harsh operating environments

Quality and Compatibility:

As an original equipment manufacturer supplier, Delphi sensors deliver the same quality and performance standards as the parts your vehicle was built with. The SS20191 is designed for precise integration with your vehicle's electronic safety systems, including ABS, traction control, and electronic stability control.

This sensor measures the rotational speed of individual wheels and transmits this data to the ABS control module, which uses the information to prevent brake lockup and maintain optimal braking performance. When a wheel speed sensor fails, it typically triggers the ABS warning light and may disable the anti-lock braking system entirely, making timely replacement critical for vehicle safety.
