A.B.S 31190 Pressure Sensors

Overview of the A.B.S 31190 Pressure Sensor

The A.B.S 31190 is a high‑performance wheel speed sensor designed to provide accurate and reliable data for vehicle braking systems. Engineered with precision, this sensor plays a critical role in monitoring the rotational velocity of each wheel, ensuring optimal traction control and anti‑lock braking performance.

Key Technical Features

• Passive Sensor Design: The sensor operates without an external power source, reducing electrical load and enhancing system stability.
• High Sensitivity: Capable of detecting minute changes in wheel speed, which is essential for precise ABS modulation.
• Robust Construction: Built to withstand harsh automotive environments, including temperature extremes, vibration, and exposure to road salts.
• Compact Footprint: Its small form factor allows easy integration into existing wheel hub assemblies without requiring extensive modifications.
• Low Power Consumption: Designed to draw minimal current, thereby preserving battery life and reducing heat generation within the vehicle’s electrical system.

Compatibility with Vehicle Models

The A.B.S 31190 is specifically engineered for use in a variety of Toyota models, particularly the Hilux series. It is available for:

• Rear Left Wheel Speed Sensor – Ideal for the left rear wheel on Toyota Hilux (04‑15) and later variants.
• Rear Right Wheel Speed Sensor – Suitable for the right rear wheel, ensuring symmetrical braking performance.
• All-wheel configurations – The sensor can be paired as a single unit or in a dual set (left + right) to replace both rear wheel speed sensors simultaneously.

Installation Guidelines

Installing the A.B.S 31190 requires careful attention to detail. Follow these steps for optimal performance:

1. Remove the existing sensor: Use a suitable socket or wrench to detach the old wheel speed sensor from the hub assembly.
2. Clean the mounting surface: Ensure no debris, rust, or adhesive residue remains on the hub where the new sensor will be seated.
3. Align the sensor correctly: Position the A.B.S 31190 so that its magnetic core aligns with the wheel’s metallic ring or sensor slot.
4. Screw in place: Tighten the mounting bolt to the manufacturer’s specified torque setting, typically around 30–35 Nm for most Toyota models.
5. Reconnect electrical contacts: Attach the sensor’s wiring harness securely, ensuring a solid connection without any loose strands.
6. Test functionality: After installation, activate the vehicle’s ABS system to confirm that the sensor is transmitting accurate wheel speed data.

Performance and Reliability

The A.B.S 31190 delivers consistent performance across a wide range of operating conditions. Its passive design eliminates the need for external power, reducing potential failure points. The sensor’s high sensitivity ensures that even subtle variations in wheel rotation are captured, allowing the ABS control module to modulate brake pressure precisely.

Maintenance Tips

• Regular Inspection: Check the sensor and its wiring for signs of wear or damage during routine maintenance intervals.
• Clean Contact Points: Keep electrical connectors free from corrosion to maintain signal integrity.
• Avoid Over-Tightening: Excessive torque can strip threads; always adhere to the specified torque values.

Benefits of Choosing the A.B.S 31190

• Enhanced Safety: Reliable wheel speed data translates into more effective ABS operation, reducing stopping distances on slippery surfaces.
• Long-Term Durability: The sensor’s rugged construction ensures longevity even in demanding off‑road or commercial applications.
• Seamless Integration: Designed to fit standard Toyota Hilux hubs, the sensor requires minimal adaptation work.
• Cost-Effective Replacement: By replacing only the wheel speed sensors rather than entire ABS modules, vehicle owners can achieve significant savings.

Conclusion

The A.B.S 31190 Pressure Sensor stands out as a reliable, high‑quality component for modern braking systems. Its passive operation, precise sensitivity, and proven compatibility with Toyota Hilux models make it an excellent choice for both OEM replacements and aftermarket upgrades. Whether you are maintaining a fleet of commercial vehicles or ensuring the safety of a personal pickup, this sensor delivers the performance and durability required by today’s demanding automotive standards.
