Description
Side Impact Sensor TEMIC for Airbag for Citroën and Peugeot Vehicles
The TEMIC side impact sensor 1400576280 / 8216NZ is designed to detect lateral collisions and provide a reliable trigger signal to the airbag control unit. Ideal for professional workshops and experienced DIY enthusiasts, this sensor is commonly used on several Citroën and Peugeot models and is often searched for by its product codes 1400576280 and 8216NZ. Replacing a faulty side impact sensor restores correct airbag operation and clears related fault codes, helping ensure occupant safety after a repair or accident.
Function And Application
Side impact sensors monitor lateral acceleration and impact forces. When a threshold is exceeded, the sensor sends an immediate signal to the airbag control module to deploy the side airbags and, if applicable, activate seatbelt pretensioners. A correctly functioning sensor is essential for timely deployment during side collisions and for maintaining the integrity of the vehicle safety system.
Technical Information

Installation Recommendations
- Safety First: Disconnect the negative battery terminal and wait at least 10 minutes before beginning work to allow the airbag system capacitors to discharge.
- Location: Depending on model, the side impact sensor is typically mounted in the B-pillar area, door sill, or seat base. Verify the sensor location in the vehicle repair manual before removal.
- Removal And Fitment: Unplug the electrical connector carefully to avoid damaging terminals. Replace the sensor with the correct orientation and torque any mounting fasteners to the manufacturer’s specification.
- After Fitment: Reconnect the battery, then clear airbag fault codes with an appropriate diagnostic tool and verify that the airbag warning light extinguishes. Perform a system check following the vehicle manufacturer’s procedure.
- Recommended Tools: Trim removal tools, torque wrench, and a diagnostic scanner capable of reading SRS/airbag fault codes.
Why The Part Most Commonly Fails
Side impact sensors are robust but can fail for several reasons. The most frequent causes are direct damage from a previous collision, water ingress or corrosion at the connector, and connector or wiring harness faults caused by stretching or rubbing. After an accident, sensors may be mechanically deformed or electronically damaged and should be inspected and replaced if any doubt exists. Electrical issues such as poor grounding or intermittent contacts also generate fault codes and disable proper system operation.
Symptoms Of A Faulty Sensor
- Persistent airbag warning light on the instrument cluster.
- Stored SRS fault codes related to side impact sensor circuits when read with a diagnostic tool.
- Intermittent faults after exposure to moisture or after door/seat repairs.
Buying note: Use the product codes 1400576280 and 8216NZ when searching to ensure correct fitment. This TEMIC sensor provides OE-style compatibility for the listed Citroën and Peugeot models and is intended for professional installation or by experienced DIYers following proper safety procedures.
