Steering Angle Sensor for CITROEN C4 and C4 Picasso
Steering angle sensor compatible with Citroën C4 and C4 Picasso. OE References: 0265005486, 9662937380, 4545H8. This sensor restores accurate steering wheel position feedback used by ESP/ABS/Traction Control systems and is intended for professional workshops and experienced DIY mechanics who often search by product number.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C4; Citroën C4 Picasso
- Product Codes: 0265005486, 9662937380
- Additional Numbers: 4545H8
Function
The steering angle sensor measures the exact angle and rotational speed of the steering wheel and sends this data to vehicle control units. Its signals are critical for stability systems (ESP/ABS/TCS), adaptive steering functions and advanced driver assistance systems that rely on precise yaw and steering input information.
Symptoms Of A Faulty Sensor
- ESP/ABS/Traction Control Warning Lights Illuminated
- Unstable Or Unexpected Stability Control Interventions
- Steering Wheel Appears Off-Center Despite Straight Driving
- Error Codes Related To Steering Angle Or Yaw Sensors In Diagnostic Tool
Installation Recommendations
- Disconnect The Battery And Wait Several Minutes Before Starting Work To Disable Airbag Circuits.
- Follow Manufacturer Procedure When Removing The Airbag Module; Handle Airbag Components With Care.
- Remove Steering Wheel And Column Trims To Access The Sensor Located On The Steering Column/Clock Spring Area.
- Unplug The Electrical Connector, Remove Retaining Fasteners And Replace The Sensor With Correct Orientation.
- After Mechanical Fitment, Recalibrate The Steering Angle Sensor Using A Diagnostic Tool (DiagBox, Autel, Bosch, Or Equivalent). Proper Calibration/Zeroing Is Mandatory For Correct ESP Operation.
- Verify Functionality By Clearing Fault Codes And Performing Road Test With Diagnostic Monitoring.
Why The Part Commonly Fails
Failures Are Most Often Caused By Mechanical Wear, Moisture Ingress Or Corrosion In The Connector Area, Electrical Faults, Or Damage From Steering Column Impacts (Collisions Or Severe Steering Events). Clock Spring Degradation Can Also Affect Sensor Signals. Symptoms May Appear Suddenly After An Impact Or Gradually As Electrical Contacts Deteriorate.
Replacement Interval And Tips
There Is No Preset Service Interval For The Steering Angle Sensor. Replace When Faults Occur, After Collision Repairs Involving The Steering Column, Or When Alignment/ESP Issues Persist Despite Correct Wheel Alignment. Use OE Reference Numbers (0265005486, 9662937380, 4545H8) To Ensure Correct Fitment.
Suitable For
Designed For Technicians And Experienced DIYers Working On Citroën C4 And C4 Picasso Vehicles Who Require Accurate OE Reference Matching And Proper Calibration After Replacement.
