The
Delphi ABS Speed Sensor, MPN SS20495, is a vital part that detects wheel speed to prevent wheel lockup during braking. It is commonly used in vehicles with advanced braking systems to provide accurate speed data for the anti-lock braking system (ABS). With its precise measurements, this sensor helps reduce the risk of skidding and improves overall driving stability.
ABS Controllers, also known as ABS modules, are electronic control units that manage the Anti-lock Braking System. Typically located within the engine compartment, these units receive wheel speed sensor data to detect and prevent wheel lockup during braking events. Utilizing hydraulic control valves, the controller modulates brake pressure to individual wheels, maintaining directional stability and minimizing stopping distance. Modern units often integrate with stability control systems and feature self-diagnostic capabilities, storing fault codes for troubleshooting. Calibration and programming are frequently required upon replacement, and many units contain internal sensors requiring verification during testing.
