SS20241 Delphi ABS SPEED SENSOR OE QUALITY

Delphi SS20241 ABS Speed Sensor – OEM Quality

The SS20241 is a high‑performance wheel speed sensor designed for the Anti‑Lock Braking System (ABS) and Electronic Stability Program (ESP). Manufactured by Delphi, it delivers reliable performance that matches or exceeds original equipment specifications.

Key Functionalities

• Active Sensor Technology: Generates a magnetic field that interacts with the rotating wheel to produce accurate speed data.
• High‑Precision Output: Provides a clean, low‑noise signal for the vehicle’s control unit, ensuring precise braking and stability interventions.
• Wide Operating Temperature Range: Functions reliably from –40 °C to +120 °C, suitable for all climates.
• Robust Construction: Encased in a durable housing that resists vibration, corrosion, and impact.

Compatibility Overview

The SS20241 is engineered to fit a broad spectrum of front‑wheel vehicles. Its design accommodates the wheel hub geometry and electronic interface used by many manufacturers:

• Alfa Romeo: Corsa D, Corsa E, Alfa Romeo models.
• Abarth: Punto, Grande Punto, ABARTH models.
• Fiat: Fiat 500, Punto, PUNTO, ADAM, and other compact cars.
• Opel: Corsa D, Corsa E, Adam, and related models.
• Vauxhall: Corso III/IV, Vauxhall variants of the same platforms.

Because the sensor is an OEM‑grade component, it matches the electrical pinout and mounting specifications used in factory installations. This ensures seamless integration without the need for adapters or additional wiring.

Installation Highlights

1. Remove Existing Sensor: Detach the old wheel speed sensor by loosening the retaining bolt and disconnecting the electrical connector.
2. Align New Sensor: Position the SS20241 so that its magnetic core aligns with the wheel’s rotating metal plate. The sensor’s mounting flange should sit flush against the hub.
3. Secure Fastening: Tighten the retaining bolt to the manufacturer’s torque specification (typically 20–25 Nm).
4. Reconnect Wiring: Attach the connector, ensuring a firm contact. Verify that the polarity matches the original setup.
5. Test Functionality: After installation, run a diagnostic scan to confirm that wheel speed data is being transmitted correctly and that no ABS fault codes appear.

Performance Benefits

• Enhanced Braking Safety: Accurate wheel speed readings allow the ABS control unit to modulate brake pressure precisely, preventing wheel lock‑up during emergency stops.
• Improved Stability Control: ESP relies on real‑time wheel speed data; the SS20241’s low latency improves vehicle handling under slippery conditions.
• Long-Term Reliability: Delphi’s quality control processes ensure that each sensor meets stringent durability standards, reducing maintenance frequency.

Technical Specifications

Quality Assurance & Testing

Each SS20241 sensor undergoes a series of rigorous tests:

• Electrical Integrity Test: Verifies signal fidelity and resistance to electrical noise.
• Mechanical Stress Test: Simulates vibration, shock, and thermal cycling conditions typical in automotive environments.
• Functional Validation: Confirms that the sensor accurately reports wheel speed across the full range of operating speeds.

Maintenance Tips

• Inspect the sensor connector regularly for corrosion or loose contacts.
• Keep the sensor housing free from oil, grease, and debris that could interfere with magnetic coupling.
• If a wheel speed fault code appears, check for damaged wiring before replacing the sensor.

Conclusion

The Delphi SS20241 ABS Speed Sensor delivers OEM‑grade performance, ensuring that your vehicle’s braking and stability systems operate with maximum safety and reliability. Its broad compatibility across Alfa Romeo, Abarth, Fiat, Opel, and Vauxhall models makes it a versatile choice for technicians and automotive enthusiasts alike.
