BOSCH 0 265 008 923 Rotation Sensor

BOSCH 0 265 008 923 Rotation Sensor

The BOŚCH 0 265 008 923 Rotation Sensor is a high‑performance wheel speed sensor designed for rear axle applications in a wide range of vehicles, particularly those from the Renault family. It plays a critical role in vehicle safety systems such as ABS (Anti‑Lock Braking System), ESP (Electronic Stability Program), and traction control by providing accurate wheel rotation data to the vehicle’s electronic control unit.

Key Functionalities

• Wheel Speed Measurement: Detects the rotational speed of each rear wheel with high precision, enabling real‑time monitoring of wheel slip and loss of traction.
• ABS Integration: Supplies essential data to the ABS module, allowing it to modulate brake pressure during emergency stops and prevent wheel lockup.
• ESP & Traction Control Compatibility: Works seamlessly with ESP and traction control systems to maintain vehicle stability under various driving conditions.
• High Reliability: Built to withstand harsh automotive environments, including temperature extremes, vibration, and exposure to road salts and debris.

Technical Specifications

Installation Overview

The sensor is designed for straightforward installation on the rear wheel hub or axle assembly. The process typically involves:

1. Removal of Existing Sensor: Detach the old sensor by loosening the mounting bolts and disconnecting the cable.
2. Alignment Check: Ensure that the magnetic rotor on the wheel hub aligns correctly with the sensor’s magnetic field. Misalignment can lead to inaccurate readings.
3. Mounting: Secure the new sensor using the supplied mounting hardware, tightening bolts to manufacturer specifications.
4. Cable Connection: Connect the sensor cable to the vehicle’s wiring harness, ensuring proper polarity and secure contacts.
5. Testing: Verify sensor operation by checking the pulse output with a diagnostic tool or oscilloscope while rotating the wheel.

Compatibility Highlights

The 0 265 008 923 sensor is engineered to fit a variety of rear axle configurations, especially those found in Renault models such as:

• Renault Clio (1.2L, 1.5L, 1.6L, dCi 1.5)
• Renault Modus (Grand Modus, Modus 1.2L, 1.4L, 1.5L, 1.6L)
• Other Renault vehicles with similar rear wheel hub geometry

Its universal mounting design and standardized electrical interface make it a drop‑in replacement for OEM sensors in these platforms.

Performance Benefits

• Enhanced Safety: Accurate wheel speed data ensures that ABS and ESP systems can react promptly, reducing stopping distances and preventing loss of control.
• Durability: The sensor’s robust construction resists corrosion and mechanical shock, extending service life even in demanding driving conditions.
• Reliability Under Extreme Conditions: Maintains performance across a wide temperature range, making it suitable for both hot climates and cold winter roads.
• Ease of Maintenance: The straightforward design allows technicians to perform quick inspections and replacements without extensive disassembly.

Quality Assurance

BOSCH is renowned for its stringent quality control processes. Each sensor undergoes:

1. Functional Testing: Verification of signal integrity, pulse frequency accuracy, and response to simulated wheel rotation.
2. Environmental Stress Screening: Exposure to temperature cycling, vibration, and humidity to ensure long‑term reliability.
3. Compliance Checks: Adherence to automotive industry standards such as ISO/TS 16949 for quality management in the automotive sector.

Maintenance Tips

• Regularly inspect the sensor cable for fraying or damage, especially after road salt exposure.
• Keep the mounting area clean and free of debris to prevent misalignment during installation.
• Use a calibrated diagnostic tool to periodically verify sensor output if you experience braking or stability issues.
