ABS 30287 Wheel Speed Sensor

ABS 30287 Wheel Speed Sensor

The ABS 30287 Wheel Speed Sensor is a critical component in modern vehicle safety systems, providing real‑time data on wheel rotation to the Anti‑Lock Braking System (ABS) and Electronic Stability Control (ESC). Designed for high reliability and precision, this sensor ensures optimal braking performance across a wide range of driving conditions.

Key Functionalities

• Accurate Wheel Speed Measurement: Converts mechanical wheel rotation into electrical signals with minimal error, enabling the ABS controller to calculate slip ratios accurately.
• High Signal Integrity: Features a robust output waveform that resists noise from road debris, temperature fluctuations, and electromagnetic interference.
• Durable Construction: Encased in a hardened housing that protects against water, oil, and vibration, ensuring long‑term operation even in harsh environments.
• Low Power Consumption: Operates efficiently to reduce load on the vehicle’s electrical system while maintaining performance.

Technical Specifications

Compatibility Overview

The ABS 30287 sensor is engineered to fit a broad spectrum of vehicles, particularly those from the French and Italian automotive families. Below is an organized list of supported models:

• CITROËN: C6, C8, 407, 807, Phédra, Ulysse
• PEUGEOT: 407, 807, C6, C8, 4x4 variants
• FIAT: Ulysse, 500, 600 series
• LANCIA: 2000, 3000, Phédra, 4000

For each brand, the sensor is available in front‑axle left/right and rear‑axle left/right configurations, ensuring full coverage for four‑wheel ABS systems.

Installation Guidelines

1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove Old Sensor: Unscrew the existing sensor using a suitable socket or wrench. Carefully detach any wiring harnesses, noting their orientation.
3. Prepare New Sensor: Verify that the sensor’s mounting flange matches the wheel hub. Apply anti‑seize compound if recommended by the manufacturer.
4. Mounting: Align the sensor with the wheel hub and secure it using the original bolts. Tighten to the specified torque (typically 15–20 Nm).
5. Reconnect Wiring: Attach the harness, ensuring correct polarity and connector orientation.
6. Test Functionality: Reconnect the battery, start the engine, and observe the ABS indicator on the instrument cluster. A steady light indicates proper operation; a flashing or off light may signal wiring issues.

Diagnostic Tips

• If the ABS warning lamp remains illuminated after replacement, check for:
• Loose or damaged wiring connections.
• Incorrect sensor orientation (some models require a specific rotational direction).
• Faulty wheel speed encoder on the hub.
• Use an OBD‑II scanner to read ABS fault codes. Common codes such as P0335–P0340 indicate wheel speed sensor problems.

Maintenance & Longevity

The ABS 30287 is designed for minimal maintenance once installed. However, periodic checks are advisable:

• Inspect the sensor housing for cracks or corrosion every 20,000 km.
• Verify that the wiring harness remains intact and free from abrasion.
• Ensure that the wheel hub’s magnetic encoder is clean; debris can interfere with signal generation.

Why Choose the ABS 30287?

The combination of proven engineering, broad vehicle compatibility, and robust performance makes the ABS 30287 Wheel Speed Sensor a trusted choice for automotive technicians and enthusiasts alike. Its precise signal output guarantees that the ABS system can react instantly to wheel slip, thereby enhancing braking safety and vehicle stability.

Conclusion

Incorporating the ABS 30287 Wheel Speed Sensor into your vehicle’s braking architecture ensures reliable detection of wheel speed variations. This sensor plays an indispensable role in maintaining optimal traction, preventing lock‑ups during emergency stops, and supporting advanced stability control features. Whether you’re performing a routine replacement or upgrading an older model, the ABS 30287 delivers dependable performance that drivers can trust.
