Design Features and Construction

The sensor incorporates a durable metal housing that protects the internal electronics from vibration, moisture, and debris. The Hall effect core is calibrated to detect magnetic fields generated by a toothed wheel or magnet attached to the vehicle’s axle. When the wheel rotates, the magnetic field induces a voltage in the sensor coil, producing a series of pulses proportional to wheel speed.

Its sealed connector ensures a reliable electrical interface while preventing ingress of contaminants. The sensor also includes an internal temperature compensation circuit that maintains signal accuracy across the specified operating range.

Applications Across Vehicle Platforms

• Land Rover Range Rover Sport: Used as part of the ABS and traction control systems to monitor wheel speed during high‑performance driving.
• Compact and Mid‑Size Cars: Integrated into standard ABS modules for enhanced braking safety.
• Commercial Vehicles: Employed in heavy‑duty trucks where precise wheel monitoring is critical for load management.

Installation Guidelines

1. Remove the existing sensor: Disconnect the battery, locate the sensor bracket on the wheel hub, and unscrew the mounting bolts.
2. Align the new sensor: Position the Bosch 0265007924 so that its magnetic core faces the toothed wheel or magnet. Use the alignment pins to ensure proper orientation.
3. Screw in place: Tighten the mounting bolts to the manufacturer’s torque specification (typically 30 Nm).
4. Reconnect the electrical connector: Ensure a secure, crimped connection to avoid signal loss.
5. Test the system: After re‑installing the wheel and restoring power, activate the vehicle’s ABS diagnostic mode to confirm sensor operation.

Diagnostic and Troubleshooting Tips

• If the ABS light remains illuminated after replacement, verify that the sensor is correctly aligned with the wheel gear or magnet.
• Check for any loose wiring or damaged connectors; a poor connection can mimic a faulty sensor.
• Use an oscilloscope to inspect the pulse waveform; irregularities may indicate electromagnetic interference or a defective unit.

Compatibility and OEM Status

The Bosch 0265007924 is listed as an OEM replacement part for several vehicle models, including certain Land Rover Range Rover Sport variants. Its design adheres to Bosch’s stringent quality standards, ensuring that it matches the performance of the original component.
