Description
Kinetic ESP Sensor BOSCH for Citroën C4 and C4 Picasso
High-quality Bosch ESP sensor (part number 0265005292) designed for Citroën C4 and Citroën C4 Picasso. This sensor provides accurate dynamic information to the vehicle stability control (ESP/ESC) system, helping to maintain traction and directional stability. Ideal for professional workshops and experienced DIY mechanics who need a direct-fit replacement by part number (0265005292 / 9649904380 / 454921).
Technical Information
- Manufacturer: Bosch
- Model: Citroën C4; Citroën C4 Picasso
- Product Codes: 0265005292; 9649904380; 454921
- Additional Numbers: 0265005292, 9649904380, 454921
Function
The sensor measures dynamic movement used by the Electronic Stability Program (ESP/ESC) to detect yaw, lateral motion or other kinetic parameters required for stability and traction control. The control unit uses this input to modulate braking and engine torque to keep the vehicle stable in critical situations.
Symptoms Of A Faulty Sensor
- ESP/ABS warning light illuminated on the dashboard.
- Reduced or erratic stability/traction control intervention.
- Unusual vehicle behavior in cornering or slippery conditions.
- Stored fault codes related to sensor signal or communication errors.
Installation Recommendation
Before starting any work, always disconnect the battery and follow the vehicle manufacturer’s safety procedure. Typical replacement steps:
- Locate the sensor according to the vehicle repair manual (location varies by model; consult technical documentation).
- Remove any trim or covers to access the sensor connector and mounting fasteners.
- Unplug the electrical connector and remove the mounting bolts.
- Fit the new sensor, secure fasteners to the manufacturer’s torque specification, and reconnect the electrical plug.
- Reconnect the battery and clear any stored fault codes.
- Perform any required sensor initialization or calibration with a suitable diagnostic tool if the vehicle requests it.
Why This Part Most Often Fails
ESP sensors commonly fail due to mechanical damage (impact or collision), moisture ingress and corrosion, wiring harness damage, connector corrosion, or internal electronic degradation over time. Symptoms often appear after water exposure, an accident, or when electrical faults develop in the surrounding circuits.
Practical Tips For Mechanics
- Verify compatibility by part number (0265005292 / 9649904380 / 454921) rather than only by vehicle model when possible.
- Check connector pins and wiring for corrosion or damage before replacing the sensor—repairing wiring faults can prevent repeat failures.
- After replacement, perform a diagnostic scan and, if required, run the vehicle-specific sensor calibration procedure to ensure correct ESP operation.
- Keep replacement sensors clean and protected from moisture during installation.
Notes For Professionals
This part is intended for professional installation or for experienced DIYers familiar with vehicle electrics and diagnostic procedures. Correct installation and, where required, calibration are essential for full ESP functionality and vehicle safety.
