Description
Side impact sensor for Peugeot 3008 and 5008 first-generation. ABL acceleration sensor.
Product Overview
This side impact (lateral) crash sensor is an original-equipment style component designed for the Peugeot 3008 I and Peugeot 5008 I platforms. It measures lateral acceleration to detect side collisions and provides a critical input to the Airbag Control Module so that side airbags and other restraint systems deploy correctly and within milliseconds of an impact. Commonly referenced by OEM codes such as 9663904980 and 8216XR, this sensor is aimed at professional mechanics and experienced DIYers who perform airbag and body repairs.
Key Benefits
- Direct fit for specified Peugeot models using OEM mounting points and connectors.
- Robust sensing element optimized for rapid detection of lateral impacts.
- Compatible with standard airbag control systems used on first-generation 3008 and 5008 vehicles.
- Often searched and ordered by part number (9663904980, 8216XR), improving findability for workshops.

Installation Recommendations
Before starting any work, always disconnect the vehicle battery and wait the manufacturer-specified time to reduce the risk of accidental airbag deployment. Removal generally requires interior trim removal in the door area or B-pillar to access the sensor housing. Disconnect the electrical connector, unbolt the sensor from its bracket, and install the replacement in the same orientation and mounting location as the original. Ensure connectors are fully engaged and that mounting bolts are secured to the original mounting points.
After installation, perform a full system check with a diagnostic tool and clear any stored fault codes. If the Airbag Control Module retains crash data or fault codes after replacement, use professional diagnostic equipment to reset the system and verify proper communication between the sensor and the control module.
How To Replace (Step-by-Step)
- Disconnect the negative battery terminal and wait according to safety guidelines.
- Remove interior trim panels to access the sensor mounting area (typically B-pillar or door inner structure).
- Unplug the sensor electrical connector and remove the mounting fasteners.
- Install the new sensor in identical orientation, secure fasteners, and reconnect the connector.
- Reinstall trim panels, reconnect the battery, then use a diagnostic scanner to clear codes and confirm system readiness.
Why This Part Fails Most Often
- Physical Damage: Direct side impacts or deformation of the door structure after a collision.
- Connector Corrosion: Moisture ingress or poor sealing at the connector can cause intermittent signals or failure.
- Internal Electronics Degradation: Age, vibration, and thermal cycling can eventually degrade the sensing element or circuitry.
- Improper Mounting: Incorrect orientation or loose mounting can prevent accurate detection of lateral acceleration.
Notes For Professionals And DIYers
This sensor is an integral part of the occupant restraint system. Replacement should be carried out by qualified personnel or experienced technicians familiar with airbag safety procedures. Use appropriate diagnostic equipment after fitting to confirm correct operation. Customers commonly look up this part by OE numbers (9663904980, 8216XR), so verifying compatibility by vehicle model and sensor location is recommended before installation.
Ordering Information
When ordering, reference the OEM part numbers listed above. The exact fit and connector type correspond to first-generation Peugeot 3008 and 5008 applications; using the correct part number ensures proper fitment and sensor orientation.
Call To Action
Choose a direct-fit side impact sensor with known OEM references to restore proper airbag function after repairs. Ideal for professional workshops and skilled DIY mechanics who require reliable, part-number-driven sourcing.
