Description
Tire Pressure Monitoring Control Unit for Citroën C5 from 2005 to 2007.
This Tire Pressure Monitoring System (TPMS) control unit is a direct-fit electronic module used on Citroën C5 II vehicles produced between 2005 and 2007. It receives signals from wheel-mounted pressure sensors, interprets sensor data and ambient conditions, and drives the dashboard TPMS warning light and related fault storage. Technically precise part numbers such as 9664177280 and 5430F6 are commonly used when searching for this unit, making it easy for mechanics and DIY enthusiasts to find the correct replacement. The module is relevant for workshops and independent repairers who service Citroën/Peugeot family cars built on shared Stellantis platforms.
Function and Fitment
The control unit centralizes tyre pressure monitoring: it collects radio or wired signals from each wheel sensor, compares pressures against programmed thresholds, and triggers a visual warning when a low-pressure condition or sensor fault is detected. Designed for Citroën C5 II (second generation), this unit helps maintain safety and vehicle stability by ensuring the driver is alerted to underinflated tyres.
Technical Information
- Manufacturer: Stellantis / Citroën
- Model: Citroën C5 II (2005–2007)
- Product Codes: 9664177280, 5430F6
- Other Numbers: NFP
Recommended Installation
Replacement should be performed by a qualified technician or an experienced DIYer with basic electrical skills. General steps:
- Disconnect the negative battery terminal to prevent short circuits and protect vehicle electronics.
- Locate the TPMS control unit (location can vary by trim and market; commonly found under the dashboard, behind the glovebox or near the central electronics fuse block).
- Remove trim panels as needed using trim tools to avoid damage, then unplug the electrical connector(s) and remove mounting fasteners.
- Install the new unit, secure fasteners and reconnect connectors ensuring good contact and no pin damage.
- Reconnect the battery, clear fault codes with a diagnostic tool and perform TPMS initialization/relearn. Some vehicles require a manufacturer-level tool (e.g., PSA DiagBox) or a compatible OBD/TPMS tool to register sensor IDs and reset the system.
- Verify proper operation by checking TPMS status and performing a driven test or sensor relearn procedure as specified in the service manual.
Why This Part Fails
Common failure causes include water ingress and corrosion of connectors, electrical stress from voltage spikes, internal component aging, and mechanical damage from improper handling. Environmental exposure (moisture, road salt) and long service life are frequent contributors. In some cases, persistent sensor faults or battery failures in wheel sensors produce error conditions that can make the control unit appear defective, so a systematic diagnosis is recommended before replacement.
Practical Notes For Buyers
When searching for this unit, using the product codes (9664177280, 5430F6) will speed up identification. Ensure the replacement matches the vehicle’s year and equipment level. After installation, plan for diagnostic initialization and a short road test to confirm that the TPMS warning lamp behaves correctly and no fault codes remain stored.
