VEMO V22-72-0097 Brake

VEMO V22‑72‑0097 Brake Sensor Overview

The VEMO V22‑72‑0097 is a high‑performance ABS wheel speed sensor designed for front wheels of Citroën and Peugeot models such as the Berlingo, C4, Partner, and related MPVs. It plays a critical role in vehicle safety by providing accurate wheel rotation data to the Anti‑Lock Braking System (ABS) and Electronic Stability Program (ESP). This sensor ensures that braking force is optimally distributed, preventing wheel lockup during emergency stops.

Key Functional Characteristics

• Precision Wheel Speed Measurement: Utilizes a magnetic or inductive pickup to detect the rotation of the wheel hub with high resolution, enabling the ABS controller to calculate slip ratios accurately.
• Robust Construction: Encased in a weather‑sealed housing that resists moisture, dust, and temperature extremes typical of automotive environments.
• Low Power Consumption: Designed to operate within the vehicle’s electrical system without drawing excessive current, thereby preserving battery life.
• Compact Size: Fits seamlessly into existing wheel assemblies, making it a direct replacement for OEM units.

The sensor is engineered to match the specifications of the original equipment (OE) for a range of models. It is compatible with:

• Citroën Berlingo (B9) from 2014 onwards
• Citroën C4 and C4 Picasso series
• Peugeot Partner, First, MPV, and Grand Raid models
• Other vehicles sharing the same wheel hub geometry and electronic interface (e.g., 4545.E7).

Installation typically involves removing the existing wheel speed sensor from the front axle, aligning the new unit with the wheel hub, and securing it with the original mounting hardware. The sensor’s electrical connector plugs directly into the vehicle’s ABS module.

The V22‑72‑0097 delivers a square wave output whose frequency is proportional to wheel speed. This signal is fed to the ABS control unit, which interprets it in real time. The sensor’s design ensures minimal noise interference, maintaining signal fidelity even under high vibration conditions.

• High‑Temperature Resistance: Operates reliably up to +120 °C, accommodating the heat generated by braking systems.
• Corrosion Protection: The housing is coated with a protective layer that resists rust and chemical exposure from road salts and de‑icing agents.
• Long Service Life: Expected to function for thousands of miles before requiring replacement, thanks to its durable magnetic core and robust sensor elements.

1. Safety First: Ensure the vehicle is securely lifted and supported on jack stands. Disconnect the battery to prevent accidental electrical discharge.
2. Remove Old Sensor: Use a socket set to detach the sensor from its mounting bracket. Carefully note the orientation of the connector for proper reassembly.
3. Align New Unit: Position the V22‑72‑0097 so that its magnetic pickup aligns with the wheel hub’s gear teeth or magnetic strip, depending on the vehicle design.
4. Secure Mounting: Tighten the mounting bolts to the manufacturer’s torque specifications. Over‑tightening can damage the sensor housing.
5. Reconnect Electrical Connector: Plug the sensor’s connector into the ABS module, ensuring a snug fit to avoid intermittent signals.
6. Test Functionality: Reconnect the battery and start the vehicle. Use an OBD‑II scanner or diagnostic tool to verify that wheel speed data is being transmitted correctly and that no fault codes are present.

If a driver experiences ABS warning lights or reduced braking performance, the V22‑72‑0097 may be the culprit. Common diagnostic steps include:

• Checking for loose or damaged wiring harnesses.
• Inspecting the sensor housing for physical damage or contamination.
• Using a multimeter to confirm that the sensor outputs a proper square wave signal when the wheel is rotated.

• OEM Quality Assurance: Meets or exceeds original equipment specifications, ensuring seamless integration.
• Enhanced Safety: Reliable wheel speed data translates to more effective ABS and ESP interventions during critical driving situations.
• Cost‑Effective Replacement: Provides a durable alternative without compromising performance.

The VEMO V22‑72‑0097 Brake Sensor is an essential component for maintaining the safety and reliability of Citroën and Peugeot vehicles equipped with ABS. Its precise wheel speed measurement, robust construction, and ease of installation make it a preferred choice for automotive technicians and vehicle owners alike. By ensuring accurate data transmission to the braking system, this sensor helps preserve vehicle stability and passenger safety across a wide range of driving conditions.
