Description
Tire Pressure Monitoring Control Unit for PEUGEOT 407
High‑quality control module dedicated to the Tire Pressure Monitoring System (TPMS) on Peugeot 407 vehicles. This unit (OEM numbers 9664177280 / 5430G0) receives signals from wheel sensors, evaluates pressure and sensor status, and supplies validated data to the instrument cluster. Designed for professional workshops and skilled DIY mechanics who search by part number, this TPMS control unit restores reliable tyre pressure monitoring and clears false warnings resulting from a faulty module.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Peugeot 407
- Product Codes: 9664177280
- Additional Numbers: 5430G0
Function And Typical Symptoms Of Failure
The TPMS control unit collects radio signals from wheel pressure sensors, processes measured pressure and temperature data, and forwards status information to the dashboard. When the control unit malfunctions, common symptoms include persistent TPMS warning lamp, missing or intermittent tyre pressure readings for one or more wheels, and inconsistent messages after sensor replacement. Fault codes related to sensor reception or internal communication errors may be stored and readable with a diagnostic tool.
Replacement And Commissioning
General replacement steps for experienced technicians or competent DIYers:
- Always disconnect the negative battery terminal before starting to avoid electrical damage.
- Locate and remove interior trim panels to access the control unit (position varies between vehicles; consult repair manual for exact location).
- Unplug the electrical connector and remove the unit from its bracket.
- Install the replacement unit in the original mounting position, connect the harness and secure fastenings.
- Re‑connect the battery and clear any stored fault codes with a diagnostic tool.
- Reinitialise or relearn the TPMS sensors. Relearn can be performed automatically on some vehicles by driving at a steady speed for several minutes or by using a diagnostic tool to read and program sensor IDs. If sensors were replaced at the same time, program new sensor IDs as required.
Recommended Installation Tips
- Handle connectors carefully and inspect for corrosion or damaged pins before fitting the new unit.
- Ensure the unit is mounted securely and away from water ingress paths—moisture is a frequent cause of failure.
- After installation, check for software or calibration procedures described in the vehicle service manual; use a capable diagnostic tool to erase codes and confirm proper communication with the instrument cluster.
- Use protective gloves and follow electrostatic discharge precautions when handling electronic modules.
Typical Lifespan And Maintenance
Control units commonly outlast individual TPMS sensors; tyre sensor batteries typically last 5–10 years depending on use and environment. The TPMS control module itself can fail earlier if exposed to moisture, corrosion, or voltage spikes. Regular visual checks of connectors and addressing wheel sensor issues promptly will prolong overall system reliability.
Why This Part Most Often Fails
The most frequent causes of TPMS control unit failure are water ingress and corrosion at the connector or housing, electrical surges (for example after jump‑starting with incorrect polarity), and physical damage from impact or poor mounting. Faulty or weak wheel sensor batteries can also create the appearance of a central unit failure by causing repeated error messages and communication timeouts.
