SS20031 Delphi ABS SPEED SENSOR

This Delphi branded ABS speed sensor, part number SS20031, plays a crucial role in maintaining vehicle stability. Located at each wheel, it detects rotational speed and transmits this information to the vehicle’s ABS control system. Accurate speed monitoring enables the ABS to prevent wheel lockup during braking, increasing safety. Its dimensions are 220 x 115 x 40 mm. Dimensions are provided by the supplier and may include packaging dimensions. 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.
