Description
Steering angle sensor for Citroën C4 and C4 Picasso vehicles.
The Steering Angle Sensor is a critical electronic component that measures the exact position and rotation angle of the steering wheel. Designed for Citroën C4 and C4 Picasso models, this sensor ensures reliable operation of driver assistance systems such as Electronic Stability Control (ESC/ESP), ABS-dependent functions, traction control and some power steering/driver assist features. Supplied with original-equivalent codes, it is an ideal replacement part for workshops and DIY mechanics looking for a direct-fit solution that restores sensor accuracy and safety systems performance.
Benefits And Application
Easy-to-fit direct replacement for affected Citroën C4 and C4 Picasso vehicles. Restores correct steering angle information to vehicle control units for stable braking and stability interventions. Improves driving safety by ensuring accurate communication between the steering column and vehicle electronic control systems.

Replacement Procedure (Overview)
Typical replacement requires removal of the steering wheel and related trim to access the sensor mounted on the steering column. Follow these general steps:
- Disconnect the negative battery terminal and wait the recommended time to disable airbags.
- Remove the driver airbag module and steering wheel according to manufacturer instructions.
- Remove steering column covers and unplug the sensor electrical connector.
- Replace the faulty sensor with the new unit, secure all fasteners to the specified torque.
- Reassemble steering wheel, airbag and covers.
- Perform steering angle sensor calibration/initialization with a diagnostic tool (DiagBox/Lexia/PP2000 or equivalent) so that ESC and related systems recognize the correct zero position.
Installation Recommendations
- Always disconnect the battery before starting work and follow the vehicle manufacturer’s safety procedures to avoid damage to the airbag system or electronic modules.
- Use the correct steering wheel and airbag removal tools to prevent damage to connectors and column components.
- After installation, calibrate the steering angle sensor with an appropriate diagnostic tool to ensure proper communication with ABS/ESP systems.
- Verify fault codes and clear any stored errors only after calibration to confirm the repair.
- If unsure about airbag or electrical procedures, have the work performed by a qualified technician.
Most Common Cause Of Failure
Steering angle sensors generally have good longevity but commonly fail due to mechanical impact (collision damage), water ingress or corrosion of connectors, internal electronic degradation, or contamination from debris. Incorrect installation or lack of proper calibration after replacement can also lead to persistent fault codes and malfunction of stability control systems.
Why Choose This Part
This steering angle sensor is supplied with manufacturer-related product codes for easy identification and compatibility with Citroën C4 and C4 Picasso models. It provides a cost-effective and reliable option for professional garages and home mechanics aiming to restore full function of ESP/ABS-related safety systems and ensure safe vehicle handling.
