Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Peugeot 307 CC
- Product Codes: 9651269480, 910946
- Additional Numbers: NFP (as listed)
Function And Application
The door handle sensor detects mechanical or capacitive activation of the exterior door handle and sends a signal to the vehicle comfort/locking system. It enables door unlocking/locking actions, hands-free access behaviors and can interact with interior lighting or alarm logic depending on vehicle configuration. On the Peugeot 307 CC it is mounted as part of the door lock/handle assembly and interfaces with the central locking electronics.
How To Replace
Replacement is straightforward for a trained technician or an experienced DIYer with basic tools. Typical steps:
- Disconnect the negative battery terminal before starting work to prevent short circuits.
- Remove interior door trim to access the lock and handle assembly (carefully detach clips and connectors).
- Disconnect the electrical connector to the sensor and unfasten any retaining screws or clips.
- Remove the faulty sensor and install the new unit in the original position, ensuring sealing and connector pins are clean.
- Reassemble the door trim and reconnect the battery. Verify correct operation by testing locking/unlocking and handle activation.
Installation Recommendations
- Always disconnect the battery before starting and follow manufacturer procedures to avoid damage to electronics.
- Inspect door seals and drainage channels during replacement—moisture is a common failure cause.
- Clean connectors and apply dielectric grease if appropriate to prevent future corrosion.
- After installation, check all door functions (central locking, interior lights, alarm) to confirm correct integration.
Why The Part Fails Most Often
Door handle sensors commonly fail due to water ingress, corrosion of electrical contacts, mechanical wear from repeated use, or damage from impact. Fault symptoms include inconsistent unlocking, having to use the key or remote to open the door, or false triggers of the central locking/alarm system. Environmental exposure (rain, road salt) and degraded seals accelerate failure.
