Description
Tire pressure monitoring control unit for Citroën C5 vehicles from 2005 to 2007.
This TPMS (Tire Pressure Monitoring System) control unit is designed for the Citroën C5 II and is listed under OE numbers 9660499380 and 5430F6. Ideal for professional workshops and experienced DIY mechanics, the unit restores accurate pressure monitoring and dashboard fault-clearing after a failed module. The part is supplied under the Stellantis group (Citroën/Peugeot) numbering and is often searched by its product codes 9660499380 and 5430F6 — include these numbers when looking up compatibility or replacement parts.
Technical Information
- Manufacturer: Stellantis
- Model: Citroën C5 (II) 2005–2007
- Product Codes: 9660499380, 5430F6
- Additional Numbers: NFP
Function
The control unit receives signals from the wheel-mounted pressure sensors, processes pressure and temperature data, and triggers dashboard warnings when a tire loses pressure or when sensor faults occur. It centralizes TPMS diagnostics and communicates with the vehicle CAN network to display fault messages and lamp warnings.
Installation Recommendations
Before replacing the unit, disconnect the negative battery terminal to avoid short circuits. Typical replacement steps:
- Locate the control unit (commonly mounted under the dash, behind glovebox, or near the central electronics module on Citroën C5 II).
- Remove necessary trim panels with plastic trim tools to avoid damage.
- Unplug connectors carefully, inspect pins for corrosion, and clean contacts if needed.
- Fit the new unit, secure fasteners, and reconnect connectors.
- Reconnect the battery and use a diagnostic tool to clear TPMS faults and, if required, re-register the wheel sensors with the new module.
Recommended tools: trim tools, Torx/socket set, multimeter for checking power and ground, and a compatible diagnostic device capable of TPMS initialization and module coding.
Most Common Failure Causes
- Moisture Ingress And Corrosion: Water penetration and corroded connector pins cause intermittent faults or complete module failure.
- Electrical Surges Or Short Circuits: Battery jump starts or wiring faults can damage the electronic components.
- Physical Damage: Impact from accidents or improper handling during repairs.
- Aging Electronics: Over time, solder joints and capacitors may degrade, leading to malfunction.
- Sensor Battery Failures: Dead wheel sensor batteries can trigger repeated faults that may be incorrectly attributed to the control unit; verify sensor status during diagnosis.
There is no fixed replacement interval for the TPMS control unit — service life depends on vehicle use, environmental exposure, and maintenance. When replacing, always verify power, ground, and communication lines first to avoid unnecessary module swaps. Using the correct product codes (9660499380, 5430F6) helps ensure you install the part that matches the original specification for Citroën C5 II (2005–2007).
