SS20283 Delphi ABS SPEED SENSOR

The Delphi ABS Speed Sensor (MPN: SS20283) is an essential part of a vehicle's electrical system. Its primary function is to measure the rotational speed of each wheel, which is then transmitted to the control unit for real-time processing. This sensor plays a critical role in maintaining stability and preventing accidents by ensuring that the vehicle's brakes can adapt to changing road conditions. 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.
