Description
Tire Pressure Monitoring System Control Unit for Citroën C5 (2005–2007).
This genuine TPMS control unit is designed for Citroën C5 II models built between 2005 and 2007. Supplied with original part numbers, it replaces a faulty tire pressure monitoring module to restore accurate pressure sensing, dashboard warning behavior and sensor communication. Ideal for professional workshops and DIY mechanics who search by part number (9664177280, 5430F6) — fits vehicles that use the same TPMS module configuration. Replacing a defective unit removes intermittent TPMS warnings, false low-pressure alerts, or loss of sensor signal.

Function And Symptoms
The TPMS control unit collects radio signals from wheel pressure sensors, validates sensor IDs and pressure data, and informs the instrument cluster of abnormal conditions. Common symptoms of a failing TPMS unit include persistent TPMS warning light despite correct tire pressures, intermittent or missing sensor readings, and inconsistent pressure values reported on the dash or diagnostic tools.
Common Reasons For Failure
- Water Ingress Or Corrosion: Moisture and road salt can corrode connectors or internal circuitry, especially in older vehicles.
- Electrical Faults: Voltage spikes, poor grounding or connector damage can cause module malfunction.
- Physical Damage: Impact, vibration or improper handling during repairs can damage the housing or PCB.
- Aging Components: Over time capacitors or other electronic components can degrade and fail.
Replacement And Installation Recommendations
- Disconnect The Battery Before Work: Always isolate the battery before removing or installing electronic modules to avoid short circuits and data corruption.
- Access And Removal: Locate the TPMS module according to vehicle-specific documentation (common locations include central electronics areas or behind dash panels). Remove trim or panels carefully to access connectors and mounting points.
- Connector Care: Inspect and clean connectors and wiring harnesses. Replace corroded pins or damaged sockets to prevent future issues.
- Installation: Fit the new unit securely, reconnect harnesses and ensure correct mounting to avoid vibration-related faults.
- Initialization / Relearn: After replacement, TPMS sensor IDs may need to be re-learned. This can be done by a dedicated TPMS tool, via a PSA diagnostic tool or by following the vehicle’s relearn procedure (driving/activation sequence). Some vehicles require registration of sensor IDs with the vehicle electronics.
- Final Check: Verify TPMS lamp extinguishes and sensor readings are stable using a diagnostic scanner or after the prescribed drive cycle.
Notes For Professionals
Searches by part number (9664177280, 5430F6) are common among technicians — confirming the part number against the vehicle’s original documentation can speed diagnosis. If the vehicle still shows TPMS faults after module replacement, inspect wheel sensors, antenna wiring and relevant fuses/grounds before assuming a new module is faulty.
Why This Part Adds Value
Replacing a malfunctioning TPMS control unit restores reliable tire pressure warnings, improves safety and prevents unnecessary tire wear. For workshops, offering replacement by part number speeds turnaround; for DIYers, clear identification of product codes ensures correct ordering and reduces fitting time.
