Description
Product Overview
This Steering Angle Sensor is designed for Citroën vehicles and provides accurate steering position data to the vehicle’s safety and assistance systems. Commonly searched by its product numbers, this sensor is compatible with Citroën C4 and C4 Picasso models and is suitable for both professional workshops and competent DIY enthusiasts.
Function And Importance
The sensor measures the angular position and rotation speed of the steering wheel and transmits this information to systems such as Electronic Stability Control (ESC), traction control, and advanced driver assistance systems (ADAS). Precise input from the steering angle sensor is critical for correct functioning of these systems and for maintaining predictable vehicle handling.
Common Failure Modes And Service Life
Sensors can fail due to internal electronic faults, moisture ingress, connector corrosion, or mechanical wear in the steering column. Symptoms of a failing sensor include warning lights on the dashboard (e.g., ESC or ABS), inconsistent steering-related diagnostics, or degraded behavior of stability and assistance systems. Service life varies with usage and environment; inspect the sensor when related fault codes appear or after steering system repairs.
Replacement And Installation Notes
Replacement should be performed by a trained technician or an experienced DIYer comfortable with steering and electronic systems. Proper mechanical installation and electrical connection are essential. After fitting a new sensor, follow manufacturer procedures for calibration or adaptation using diagnostic equipment; failure to calibrate can lead to incorrect system operation or warning lights. Check connectors, wiring and mounting points during replacement to avoid recurring faults.
