VEMO V22-72-0092 Brake

VEMO V22-72-0092 Brake Sensor – Technical Overview

The VEMO V22-72-0092 Brake Sensor is a high‑performance wheel speed sensor designed for the rear axle of classic Citroën and Peugeot models. It plays a critical role in the vehicle’s Anti‑Lock Braking System (ABS), providing accurate wheel rotation data to the electronic control unit. This sensor is engineered for durability, precision, and seamless integration with legacy automotive electronics.

Key Functional Attributes

• Passive Sensor Design: Operates without an external power source, drawing energy from the vehicle’s electrical system.
• High Accuracy: Delivers precise wheel speed measurements, essential for effective ABS and Electronic Stability Program (ESP) operation.
• Robust Construction: Built to withstand harsh automotive environments, including temperature extremes and vibration.
• Compact Footprint: Fits within the limited space of rear wheel assemblies on older models.
• Easy Installation: Compatible with standard mounting brackets and connectors used in Citroën Saxo, Peugeot 106 II, and similar vehicles.

Compatibility Matrix

The V22-72-0092 is specifically engineered for the following vehicle platforms:

Electrical Specifications

• Voltage Range: 12 V DC (typical automotive battery supply)
• Signal Type: Pulse‑width modulation (PWM) output to the ABS control unit.
• Impedance: Standard automotive sensor impedance (typically 500 Ω).
• Operating Temperature: –40 °C to +85 °C.
• Operating Humidity: Up to 95 % non‑condensing.

Installation Guidelines

1. Remove Existing Sensor: Carefully detach the old wheel speed sensor from the rear axle housing, noting any wiring harness connections.
2. Align Sensor: Position the V22-72-0092 so that its magnetic core aligns precisely with the wheel’s toothed rim or gear.
3. Secure Mounting: Fasten the sensor using the supplied mounting bracket and torque specifications to ensure a firm fit.
4. Reconnect Wiring: Attach the sensor’s connector to the vehicle’s ABS harness, ensuring a secure and correct polarity connection.
5. Test Functionality: Verify sensor operation by checking the ABS diagnostic port for proper wheel speed signals and ensuring no fault codes appear.

Performance Benefits

• Improved Braking Stability: Accurate wheel speed data allows the ABS system to modulate brake pressure effectively, reducing wheel lock‑up during emergency stops.
• Enhanced Vehicle Dynamics: Reliable sensor input supports ESP functions, helping maintain vehicle control during cornering or sudden maneuvers.
• Long‑Term Reliability: The sensor’s robust design minimizes failure rates, ensuring consistent performance over the vehicle’s lifespan.
• Low Maintenance: Passive operation eliminates the need for additional power supply components, reducing potential failure points.

Quality Assurance and Standards

The V22-72-0092 adheres to stringent automotive industry standards, including:

• ISO 9001: Quality management system certification.
• ISO/TS 16949: Automotive-specific quality management.
• CE Marking: Compliance with European Union safety, health, and environmental protection requirements.
• RoHS Compliance: Restriction of hazardous substances in electronic equipment.

Maintenance and Troubleshooting Tips

• Regular Inspection: Check for physical damage, corrosion, or misalignment during routine maintenance.
• Signal Verification: Use a diagnostic scan tool to confirm that the sensor outputs consistent wheel speed pulses.
• Connector Integrity: Ensure that the wiring harness connector is free from dirt, moisture, and corrosion.
• Replacement Procedure: If a fault code indicates sensor failure, replace the unit with an identical V22-72-0092 to maintain system integrity.

Conclusion

The VEMO V22-72-0092 Brake Sensor is a critical component for maintaining the safety and performance of classic Citroën and Peugeot vehicles equipped with ABS.
