Description
Inertial control unit, kinetic ESP sensor BOSCH for Citroën and Peugeot vehicles
Description
High-quality Bosch inertial (kinematic) sensor for ESP/ABS systems, designed for use on Citroën and Peugeot vehicles. The unit measures vehicle dynamics and provides the stability control system with real-time inertial data to manage braking interventions and traction control. Ideal for professional workshops and skilled DIY mechanics looking to restore correct ESP functionality. Customers frequently search by part numbers 0265005714 and 9663187680, so this listing includes full cross-reference numbers for fast identification.
Applications
Direct fit for select Stellantis models equipped with the matching ESP system. Typical applications include:
- Citroën C4
- Citroën C8
- Peugeot 307
- Peugeot 407
- Peugeot 807
Technical Information
- Manufacturer: Bosch
- Model: Inertial/Kinematic ESP Sensor (for Citroën and Peugeot)
- Product Codes: 0265005714, 9663187680
- Additional Numbers: 9811627180, 454939
How The Part Works
The sensor senses vehicle acceleration and kinematic movement and sends processed data to the ESP/ABS control unit. Based on this input, the stability control system modulates individual wheel braking and engine torque to maintain vehicle stability under evasive maneuvers, slippery surfaces or abrupt steering corrections.
How To Replace
Replacement requires careful handling and correct orientation of the sensor. Typical replacement steps:
- Park on level ground and disconnect the negative battery terminal before starting work.
- Locate the inertial sensor (usually mounted on the vehicle floor, center tunnel or under the dashboard depending on model).
- Unplug the electrical connector and remove the mounting fasteners.
- Install the new sensor in the exact orientation, secure fasteners to the manufacturer specification and reconnect the connector.
- Reconnect the battery and clear any fault codes.
- Perform sensor calibration/initialization according to manufacturer procedure using a diagnostic tool or follow the prescribed drive calibration routine.
Installation Recommendations
Ensure the mounting surface is clean and free of corrosion or deformation. Tighten mounting bolts to the correct torque and verify the sensor is seated without play. After fitting, the sensor will usually require initialization or calibration with a diagnostic tool appropriate for PSA vehicles; without calibration the ESP/ABS system may report faults or operate incorrectly. Always perform a road test to confirm proper system operation and that no warning lights remain on.
Why This Part Commonly Fails
Failures are most often caused by environmental or mechanical damage rather than wear: water ingress, corrosion at the connector, impact from collisions or improper mounting can damage the internal electronics. Electrical faults such as short circuits, damaged wiring or connector corrosion also cause sensor malfunction. Symptoms include ESP/ABS warning lights, loss of stability control or incorrect ABS behavior.
Notes
There Is No Scheduled Replacement Interval For This Sensor. Replace When Fault Codes Appear Or After An Accident That May Have Affected The Unit Or Its Mounting. Proper Calibration After Installation Is Essential For Reliable ESP Operation.
