Description
Steering angle sensor for Citroën and Peugeot vehicles. Suitable for Citroën C5 X7, C4 Picasso, C4.
High-quality steering angle sensor designed for Citroën/Peugeot applications, optimised for reliable operation of the ABS/ESP and stability systems. This unit is commonly referenced under part numbers 0265005517, 9658684180 and 4545H8 and is a direct replacement for worn or faulty original sensors used on several Citroën models. Clear-fit installation and correct calibration restore accurate steering position information to the vehicle control units, eliminating related warning lights and steering-assist faults.
Features and Benefits
– Direct-fit replacement for OE referenced steering angle sensors, ensuring correct electrical and mechanical fit.
– Restores accurate steering position data to ABS/ESP and traction control systems.
– Improves vehicle safety and drivability by eliminating erroneous stability control interventions.
– Essential spare part for workshops and DIY mechanics who maintain Citroën C5 X7, C4 Picasso and C4 models.

How It Works
The steering angle sensor measures the rotational position of the steering column and communicates this information to safety systems such as ABS, ESP and traction control. The control units use this data to determine vehicle yaw and to intervene when slip or instability is detected. Accurate sensor data is therefore essential for predictable braking and stability behaviour.
Common Failure Modes
Steering angle sensors generally have a long service life but can fail for several reasons:
- Electrical faults or connector corrosion leading to intermittent or lost signal.
- Damage from steering column impacts or accidents that disturb the sensor or its mounting.
- Wear of internal components or encoder elements over time.
- Faults introduced during incorrect removal/installation, especially when the steering wheel/airbag is handled without proper procedure.
Replacement Frequency
There is no fixed replacement interval; the sensor is replaced when it fails or after events that may affect steering geometry (e.g., accidents). If ABS/ESP warning lights appear, or if vehicle stability systems behave unpredictably, the steering angle sensor should be inspected and, if necessary, replaced and recalibrated.
Installation Instructions
General replacement steps for experienced technicians and competent DIY mechanics:
- Park vehicle on level ground, engage the handbrake and place the front wheels straight ahead.
- Disconnect the negative battery terminal and wait at least two minutes to ensure SRS capacitors discharge.
- Remove the driver airbag and steering wheel following manufacturer safety procedures.
- Access the steering column trim and locate the steering angle sensor/clock spring assembly.
- Disconnect the sensor electrical connector and unfasten the sensor from its mount.
- Fit the new sensor in the centred position, secure mechanically and reconnect the wiring harness.
- Reassemble the steering wheel and airbag. Reconnect the battery.
- Perform steering angle sensor calibration with a suitable diagnostic tool and clear any stored fault codes. Verify ABS/ESP system operation and that no warning lights remain.
Recommended For Installation
Use correctly rated hand tools and follow vehicle manufacturer procedures when removing the airbag and steering wheel. Calibration with a compatible diagnostic tool (for PSA vehicles typically DiagBox or an equivalent professional scan tool) is required after replacement to synchronise the sensor with the vehicle control units. Failure to calibrate can result in persistent ABS/ESP faults or incorrect system behaviour.
Why This Part Is Often Replaced
Technicians most frequently replace the steering angle sensor after ESP/ABS warning lights appear, following steering column impacts, or when diagnostics show angle sensor faults. In some cases, failures become apparent after airbag service or steering wheel removal where the sensor or its alignment is disturbed.
