ABS 30335 Wheel Speed Sensor

ABS 30335 Wheel Speed Sensor

The ABS 30335 Wheel Speed Sensor is a precision‑engineered component designed to monitor the rotational speed of a vehicle’s wheel and transmit this data to the Anti‑Lock Braking System (ABS). By providing real‑time feedback on wheel velocity, the sensor enables the ABS controller to modulate brake pressure, preventing wheel lockup during emergency stops or slippery conditions. This ensures optimal traction, stability, and safety for both front and rear wheels.

Key Features

• High Accuracy: Detects wheel speed with minimal error, ensuring reliable ABS performance.
• Durable Construction: Encased in a robust housing that resists vibration, heat, and corrosive environments typical of automotive applications.
• Passive Sensor Design: Operates without requiring external power; it generates its own signal through the vehicle’s magnetic field.
• Compact Size: Fits seamlessly into standard wheel hub assemblies, maintaining optimal weight distribution.
• Wide Temperature Range: Functions effectively from –40 °C to +120 °C, accommodating diverse climates and driving conditions.

Technical Specifications

Installation Guide

1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove Old Sensor: Locate the wheel hub, unscrew the sensor mounting bolt, and gently detach the sensor from its housing.
3. Prepare New Sensor: Inspect the new ABS 30335 for any visible damage. Ensure the sensor’s contact points are clean.
4. Mounting: Align the sensor with the wheel hub, insert the mounting bolt, and tighten to the manufacturer’s torque specification (typically 30–40 Nm).
5. Reconnect Battery: Reattach the battery terminals securely.
6. Diagnostic Check: Use an OBD‑II scanner or ABS diagnostic tool to verify sensor operation and confirm no fault codes are present.

Common Applications

• Front wheel ABS sensors for Daewoo Lanos, Nubira, Orion, Assol, Aranos, and other models with a 28 mm hub diameter.
• Rear wheel ABS sensors where the same sensor specifications apply.
• Replacement parts in aftermarket repair shops focusing on European and Asian vehicle platforms.

Performance Benefits

The ABS 30335 Wheel Speed Sensor delivers consistent, high‑resolution wheel speed data that allows the ABS controller to:

• Prevent wheel lockup during hard braking, reducing stopping distance.
• Maintain vehicle stability on uneven or slippery surfaces.
• Provide accurate input for traction control and electronic stability programs.

Quality Assurance

Each sensor undergoes rigorous testing to meet automotive industry standards. The manufacturing process includes:

• Electrical performance verification under simulated driving conditions.
• Environmental stress tests for temperature, vibration, and humidity resilience.
• Dimensional inspections to ensure precise fitment on standard wheel hubs.

Maintenance Tips

• Inspect the sensor housing periodically for cracks or corrosion.
• Clean contact points with a non‑abrasive brush if debris accumulates.
• Avoid exposing the sensor to oil, grease, or excessive moisture, which can impair signal integrity.

Conclusion

The ABS 30335 Wheel Speed Sensor is a critical component for modern vehicle safety systems. Its reliable performance, durable construction, and compatibility with a range of Daewoo models make it an essential choice for both OEM replacements and aftermarket restorations. By ensuring accurate wheel speed detection, this sensor plays a pivotal role in maintaining safe braking dynamics across diverse driving environments.
