Product Overview

High-quality Bosch ESP kinetic sensor designed for Citroën and Peugeot models. This sensor provides crucial vehicle dynamics information to the ESP/ABS systems, improving stability control and braking performance. Commonly referenced by part numbers 0265005253 and 9645447780, it is a direct-fit replacement for affected factory units used on selected Citroën and Peugeot platforms.

Why This Part Matters

The ESP kinetic sensor supplies the vehicle stability control with real-time data about vehicle motion (such as rotational and inertial signals). The information is used by the ESP/ABS control unit to detect skids, intervene with braking on individual wheels, and adjust engine torque to maintain vehicle stability. A faulty sensor can lead to reduced stability control performance and trigger warning lights such as ESP or ABS on the dash.

Replacement Procedure (Overview)

The following steps describe the typical replacement process. Procedures can vary by model—refer to the vehicle’s service manual for exact instructions:

1. Park the vehicle on level ground, engage the parking brake and disconnect the battery.
2. Locate the faulty ESP sensor (location varies by model and sensor type) and gain access by removing any necessary trim or covers.
3. Disconnect the electrical connector and remove the mounting fasteners.
4. Install the new sensor, secure mounting fasteners to the manufacturer’s torque specification and reconnect the electrical connector.
5. Reconnect the battery, clear fault codes with a diagnostic tool and perform any required calibration or system checks.

Installation Recommendations

• Always Disconnect The Battery Before Starting Work To Prevent Short Circuits And Protect Electronics.
• Inspect Connectors And Wiring For Corrosion Or Damage; Replace Damaged Clips Or Harness Sections.
• Tighten Mounting Fasteners To The Manufacturer’s Specified Torque To Ensure Correct Sensor Positioning.
• After Installation, Use A Diagnostic Tool To Clear Stored Fault Codes And Verify ESP/ABS System Operation. If The Vehicle Requires Calibration, Follow The Manufacturer’s Procedure.
• For Complex Diagnostics Or Calibration Tasks, Use Proper Diagnostic Equipment Commonly Used On PSA Vehicles (e.g., DiagBox/Lexia/PP2000) Or Seek A Qualified Technician.

Common Failure Causes

• Connector Corrosion Or Water Ingress Leading To Intermittent Signals.
• Physical Damage From Road Debris, Impact Or Improper Handling During Repairs.
• Internal Electronic Failure Due To Age, Thermal Stress Or Vibration.
• Faults In Related Wiring Or Ground Connections Causing Signal Loss.
• Post-Accident Distortion Of Mounting Points Or Body Structure Affecting Sensor Alignment.

Practical Notes For Mechanics And DIY Enthusiasts

This Bosch sensor is a commonly replaced component when ESP/ABS faults are present or when stability control performance is compromised. Keep the vehicle’s fault codes and the OE part number at hand when diagnosing. Replacing the sensor is straightforward for an experienced mechanic, but correct diagnosis, connector inspection and post-replacement verification are essential to ensure the ESP system works reliably.
