Description
Front and rear body height sensor for Citroën C5 2001-2007. Used part with guarantee of functionality.
This ride height sensor is intended for the front and rear suspension of Citroën C5 models produced between 2001 and 2007. The sensor measures vehicle body height and sends the signal to the suspension control system to maintain correct leveling. Commonly searched by OE numbers 9641247280 and 5273J4, this unit is suitable for professional mechanics and experienced DIYers looking for a direct replacement for vehicles equipped with hydraulic/hydropneumatic height control.
Technical Information
- Manufacturer: Citroën / Peugeot (Stellantis)
- Model: Citroën C5 (2001-2007)
- Product Codes: 9641247280, 5273J4
- Other Numbers: None specified
Installation Recommendations
- Work Safely: Park on a level surface, apply the handbrake and use axle stands when lifting the vehicle. Wear safety gloves and eye protection.
- Access: On many C5 models the sensor is accessible from the wheel arch or by lowering the suspension to relieve linkage tension. Remove the wheel or inner splash guard if needed for clear access.
- Remove Old Unit: Disconnect the electrical connector, free the sensor linkage from the suspension arm (retain or replace securing clips), then unbolt the sensor from its mounting bracket. Use penetrating oil if fasteners are corroded.
- Fit New Unit: Install the new sensor in the same orientation, secure the mounting fastener and reconnect the linkage and electrical connector. Ensure connectors are clean and seated firmly to avoid intermittent faults.
- Post-Fit Check: Cycle the ignition and observe suspension behavior. Some vehicles self-calibrate; on others a diagnostic tool may be required to initiate calibration or to confirm correct sensor values.
- Tools & Tips: Metric socket set, pliers, electrical contact cleaner and dielectric grease for connectors improve reliability after installation.
Most Common Failure Reasons
- Corrosion and water ingress at the sensor body or electrical connector, especially on older vehicles.
- Mechanical damage to the linkage or sensor pivot from road debris or impact.
- Wear of the sensor linkage ball/joint leading to play and incorrect height readings.
- Electrical faults such as broken wires, poor crimped connectors or intermittent contacts.
- Seizing of moving parts after long service life, especially in harsh climates.
Search tip: Many customers find this part using OE numbers 9641247280 or 5273J4. Verify the mounting position (front or rear) and connector type against the vehicle before installation to ensure correct fitment.
