Description
Kinetic ESP sensor Bosch for Citroën C4 and C8 II, Peugeot 307 II and 807 II.
High-quality Bosch kinetic ESP (yaw/acceleration) sensor designed for Citroën and Peugeot vehicles. This sensor supplies the ABS/ESP control unit with precise lateral acceleration and rotational (yaw) data, enabling stability and traction control systems to react correctly in emergency maneuvers. Ideal for professional workshops and experienced DIY mechanics, the unit matches common OEM part references and is a direct replacement for failed or faulty sensors in the listed models.
Key Benefits
Reliable Bosch sensing element optimized for PSA stability systems. Fast fault isolation when pairing part numbers (see technical information). Restores correct ESP/ABS functionality, eliminates warning lights related to stability control, and ensures the vehicle’s electronic safety systems operate as designed.
Typical Applications
Designed For: Citroën C4, Citroën C8 II, Peugeot 307 II, Peugeot 807 II. Commonly fitted where the vehicle reports ESP/ABS faults such as persistent ESP/ASR warning lamps, loss of traction control, or erroneous yaw-rate/acceleration readings.
Technical Information
- Manufacturer: Bosch
- Model: Kinetic/ESP (Yaw/Acceleration) Sensor
- Product Codes: 0265005291, 9649400180
- Additional Numbers: 9811627180, 454926, 454939
Function And How It Works
The Sensor Measures Lateral Acceleration And Yaw Rate And Sends This Data To The ABS/ESP Control Unit. The Control Unit Uses The Information To Modulate Braking And Engine Torque During Instability Events, Helping To Maintain Vehicle Trajectory. A Faulty Sensor Can Cause Incorrect Stability Control Interventions Or Trigger Warning Lights.
How To Replace
Replacement Should Be Performed By A Trained Technician Or An Experienced DIY Mechanic With Basic Tools. Typical Steps:
- Disconnect The Battery Before Starting Work To Avoid Short Circuits And Electronic Damage.
- Locate The Sensor (Usually Mounted Near The Vehicle Centreline Close To The ABS/ESP Control Unit Or Under The Dash/Centre Tunnel Depending On Model).
- Remove Any Trim Or Fastenings That Obstruct Access To The Sensor And Unplug The Electrical Connector Carefully.
- Unbolt The Sensor, Swap The Unit, And Refit Using Correct Fasteners. Do Not Overtighten; Follow Manufacturer Torque Values Where Available.
- Reconnect The Connector And Battery, Then Perform A Calibration/Initialisation Procedure If Required By The Vehicle (See Next Section).
Installation Recommendations
- Always Disconnect The Battery Before Demounting Or Installing Electronic Components.
- Handle The Sensor And Connector With Care; Avoid Impact, Contamination, And Excessive Force.
- Inspect Wiring And Connectors For Corrosion Or Damage And Repair As Necessary Before Fitting The New Sensor.
- After Replacement, Perform Any Required Calibration/Initialisation Using A Suitable Diagnostic Tool (DiagBox/Lexia/PP2000 Or Equivalent) So The ESP System Accepts The New Sensor.
Most Common Failure Causes
Sensor Malfunction Usually Results From Moisture Ingress, Corrosion Of Electrical Contacts, Mechanical Shock (Impact Or Accident), Long-Term Vibration Stress, Or Electrical Surges. Environmental Exposure (Road Salt, Water) And Damaged Wiring Are Frequent Contributors To Premature Failure.
Symptoms Of A Faulty Sensor
- Persistent ESP/ABS Warning Lights On The Dashboard.
- Intermittent Or Complete Loss Of Traction/Stability Control Functions.
- Unexpected Braking Interventions Or Unstable Behaviour During Cornering.
- Diagnostic Trouble Codes Related To Yaw Rate Or Lateral Acceleration Sensors.
Advice For Workshops
When Replacing The Sensor, Verify Wiring Integrity And Connector Condition To Avoid Repeat Failures. After Installation, Run A Full Diagnostic And Perform Any Required Sensor Calibration/Adaptation So The ESP Controller Recognizes The New Unit. Document The Repair And Test Drive The Vehicle To Confirm Normal System Operation.
Compatibility Notes
Part Numbers Listed Are Common References Used On Citroën And Peugeot Models Mentioned Above. Always Cross-Reference The Vehicle’s Existing Part Number Against The Numbers Provided To Ensure Correct Fitment.
Warranty And Quality
Bosch Sensing Technology Is Widely Used On PSA Vehicles; Replacing A Faulty Unit With A Correctly Specified Bosch Sensor Restores Original System Performance. For Professional Results, Follow Manufacturer Procedures During Installation And Calibration.
