VEMO Sensor, wheel speed V25-72-0027

VEMO Sensor – Wheel Speed V25-72-0027

The VEMO Sensor V25-72-0027 is a high‑performance wheel speed sensor designed for the rear axle of Ford Focus models (including Mk1 3/5 doors, Break, Kombi, and various engine variants). It plays a critical role in the vehicle’s Anti‑Lock Braking System (ABS), Electronic Stability Program (ESP), and other safety‑related modules by providing accurate wheel rotation data.

Key Functionalities

• Wheel Speed Detection: Measures the rotational speed of the rear wheel with high precision, enabling the ABS to modulate brake pressure during skids.
• Signal Output: Generates a low‑frequency square wave whose frequency is directly proportional to wheel velocity. This signal is fed into the vehicle’s control unit.
• Durability: Built with robust materials to withstand harsh automotive environments, including temperature extremes, vibration, and exposure to brake dust.
• Compact Design: Small footprint allows easy integration into existing mounting brackets without requiring major modifications.

Technical Specifications

Installation Overview

The V25-72-0027 is designed to replace the original sensor without requiring additional hardware. The installation procedure typically involves:

1. Removal of Old Sensor: Disconnect the electrical connector and unscrew the mounting bolts.
2. Alignment: Position the new sensor so that its magnetic field aligns with the wheel’s rotating toothed rim or gear.
3. Securing: Tighten the mounting bolts to the specified torque.
4. Connection: Re‑attach the electrical connector, ensuring a firm contact.
5. Verification: Use diagnostic equipment to confirm proper signal output and sensor functionality.

Compatibility Highlights

The V25-72-0027 is specifically engineered for Ford Focus models produced between 1998 and 2004, covering a range of engine configurations (1.4‑2.0 L) and body styles (sedan, hatchback, station wagon). It matches the original sensor’s mounting points and electrical interface, guaranteeing seamless integration.

Performance Benefits

• Enhanced Safety: Reliable wheel speed data ensures that ABS and ESP systems can react swiftly during emergency braking or loss‑of‑traction scenarios.
• Improved Reliability: The sensor’s robust construction reduces the likelihood of false readings caused by vibration or temperature fluctuations.
• Long‑Term Durability: Designed for extended service life, minimizing maintenance and replacement costs over the vehicle’s lifespan.

Maintenance Tips

Although the V25-72-0027 is low‑maintenance, periodic checks can help maintain optimal performance:

• Inspect the sensor housing for cracks or corrosion.
• Verify that the electrical connector remains free of debris and oxidation.
• Check mounting bolts periodically to ensure they remain tight.

Conclusion

The VEMO Sensor V25-72-0027 delivers precise wheel speed measurement essential for the safety systems of Ford Focus vehicles. Its compact, durable design and straightforward installation make it an ideal choice for both professional technicians and knowledgeable DIY enthusiasts seeking reliable performance in their rear‑axle ABS and ESP modules.
