VEMO V46-72-0118 Brake

VEMO V46-72-0118 Brake Sensor

The VEMO V46-72-0118 Brake is a high‑performance wheel speed sensor designed for modern automotive braking systems. It plays a crucial role in the vehicle’s Anti‑Lock Braking System (ABS) and Electronic Stability Control (ESC), ensuring safe and reliable operation under all driving conditions.

Key Functionalities

• Wheel Speed Detection: Measures rotational speed of each wheel with high precision, providing real‑time data to the ABS control unit.
• Brake Pressure Monitoring: Integrates pressure sensing capability to detect variations in brake fluid pressure, enhancing braking performance and safety.
• Signal Integrity: Features low‑noise output and robust filtering to maintain signal quality even under harsh electromagnetic environments.
• Self‑Diagnostics: Built‑in diagnostic routines allow the vehicle’s ECU to detect faults such as open circuits, shorted coils, or incorrect speed readings.

Technical Specifications

Compatibility and Applications

The VEMO V46-72-0118 is engineered to fit a wide range of passenger cars, light commercial vehicles, and certain truck models. It is commonly found in:

• Front‑wheel drive (FWD) platforms such as the Renault Megane series.
• Rear‑wheel drive (RWD) configurations used by Nissan and Dacia models.
• Hybrid and electric vehicles that require precise wheel speed feedback for regenerative braking control.

Its modular design allows seamless integration into existing ABS modules, eliminating the need for extensive reprogramming or hardware modifications.

Installation Guidelines

1. Preparation: Disconnect the vehicle’s battery to prevent accidental electrical discharge. Remove the wheel and access the brake assembly.
2. Removal of Old Sensor: Unscrew the mounting bolts securing the previous sensor. Carefully detach the wiring harness, noting the pin configuration.
3. Mounting New Sensor: Position the VEMO V46-72-0118 in the designated slot, aligning the magnetic pole with the wheel hub’s rotor. Secure it with the supplied bolts and torque specifications.
4. Wiring Connection: Connect the sensor’s harness to the vehicle’s ECU or ABS module. Ensure polarity is correct; reverse connections can lead to system failure.
5. Testing: Reconnect the battery, start the engine, and verify that the ABS light remains off. Use a diagnostic scan tool to confirm wheel speed readings are within expected ranges.

Maintenance Tips

• Inspect the sensor’s housing for cracks or corrosion periodically; replace if damaged.
• Check wiring insulation for wear, especially near the steering column where flexing occurs.
• Keep the magnetic pole clean from oil and brake dust to maintain accurate speed detection.
