Description
Side Impact Sensor For Airbag For Citroën And Peugeot Vehicles
This side impact sensor is designed for the airbag system on Citroën and Peugeot vehicles, helping the Supplemental Restraint System (SRS) detect lateral collisions and trigger appropriate airbag deployment. The part is commonly searched by part numbers 1490426080 and 8216NZ, which makes it quick to find for professional garages and DIY mechanics looking to restore correct SRS functionality.
The sensor converts mechanical shock from a side impact into an electrical signal that the airbag control unit interprets. A functioning side impact sensor is critical for timely deployment of side and curtain airbags; a faulty sensor typically results in SRS warning lights and logged fault codes, and must be addressed to ensure occupant safety. This unit is compatible with a range of Stellantis models and is suitable when the existing sensor is physically damaged, electrically unstable, or reporting persistent error codes.
Technical Information
- Manufacturer: TEMIC
- Applicable Models: Citroën C2, Citroën C3, Citroën C3 Pluriel, Citroën C8, Peugeot 1007, Peugeot 807
- Product Codes: 1490426080, 8216NZ
- Additional Numbers: Stellantis OEM application (Citroën / Peugeot group)
Installation Recommendations
- Always follow SRS safety procedures: disconnect the negative battery terminal and wait at least 10 minutes before working on the airbag system to allow residual charge to dissipate.
- Locate the sensor (commonly mounted in the B-pillar area, door frame or behind trim panels depending on model). Remove trim panels carefully to avoid damaging clips and connectors.
- Unplug the electrical connector using the locking tab, remove the mounting fasteners, and replace the sensor with the new unit in the same orientation.
- Use the correct torque for mounting screws (refer to vehicle workshop manual). Ensure connectors are clean, fully engaged and the locking clip is secure.
- After installation, clear SRS fault codes with a diagnostic tool and verify that the airbag warning lamp on the instrument cluster extinguishes. If the warning lamp remains on, re-check wiring, connector condition and sensor seating.
- If you are not experienced with airbag systems, have the replacement performed or checked by a qualified technician — improper handling of SRS components risks incorrect operation or accidental deployment.
Why This Part Most Commonly Fails
- Physical Damage From Collisions: The sensor can be damaged in a side impact or during repairs following an accident.
- Connector Or Wiring Issues: Corrosion, bent pins or broken wires at the connector cause intermittent signals or open circuits.
- Water Ingress And Corrosion: Moisture reaching the sensor housing or connector can lead to electrical faults over time.
- Age And Environmental Stress: Long-term exposure to vibration, temperature cycles and road contaminants may degrade the sensor’s internal components.
Typical Symptoms Indicating Replacement Is Needed
- Illuminated Airbag (SRS) Warning Light On The Dashboard
- Stored SRS Fault Codes Related To Side Impact Sensors
- Visible Damage To Sensor Or Connector After An Accident
- Intermittent Faults Or Communication Errors Between Sensor And Airbag Control Unit
Part numbers such as 1490426080 and 8216NZ are commonly used when searching for this sensor, so including these codes in your order or search will speed up locating the correct replacement. Proper installation and diagnostic clearing are essential to restore full SRS functionality and ensure occupant protection in the event of a side collision.
