Function And Typical Faults

The TPMS Control Unit Collects And Processes Signals From Wheel Mounted Sensors, Then Sends Tyre Pressure Status To The Instrument Cluster Via The Vehicle Network. It Also Manages Fault Detection And Warning Logic. Units Fail Mainly Due To Electrical Issues, Moisture Ingress, Corrosion Of Connectors, Or As A Secondary Effect Of Repeated Faults From Depleted Wheel Sensor Batteries. Failures Can Result In Constant TPMS Warnings, Intermittent Readings, Or Loss Of Communication With Some Or All Wheel Sensors.

How Often It Fails

There Is No Fixed Interval For TPMS Module Failure; Lifespan Depends On Vehicle Use, Environmental Conditions And Exposure To Moisture Or Road Salt. In Practice, Units From Older Vehicles Or Vehicles With Previous Water Damage Or Electrical Faults Are At Higher Risk.

Replacement Procedure

Recommended Steps For Replacement (General Guidance For Experienced Mechanics/DIY):

1. Read And Save Fault Codes With A Diagnostic Tool Before Removal To Document Current Errors.
2. Disconnect The Battery Before Any Disassembly To Prevent Short Circuits Or Damage To Electronic Modules.
3. Locate And Access The TPMS Control Unit (Position Can Vary By Vehicle; Often Installed In The Vehicle Interior Or Boot Area Behind Trim Panels).
4. Disconnect Electrical Connectors Carefully, Inspecting For Corrosion Or Bent Pins.
5. Swap The Unit And Reconnect Connectors Firmly; Refit Trim Panels Securely.
6. Reconnect The Battery And Clear Faults With A Diagnostic Tool. Check That The System Receives Data From All Wheel Sensors And That No Warnings Remain.

Installation Recommendations

• Always Disconnect The Battery Before Removal/Installation To Avoid Damage To The Unit.
• Inspect Connectors And Wiring For Corrosion Or Damage; Replace Or Repair As Necessary.
• Use A Compatible Diagnostic Tool To Clear Faults And Verify Communication With Wheel Sensors After Installation.
• When Replacing Due To Sensor Battery Failure, Replace Or Reinitialize The Sensors As Needed To Prevent Recurrence Of Faults.

Why This Part Is Often Replaced

TPMS Control Units Are Frequently Replaced Because Of Electrical Failures Caused By Corroded Connectors, Water Intrusion, Impact Damage, Or Cumulative Wear From Repeated Fault Conditions. In Some Cases, Replacing Faulty Wheel Sensors Without Addressing A Damaged Control Unit Will Not Resolve Persistent TPMS Warnings.

Compatibility And Identification

This Unit Is Identified By OE Numbers 9664177280 And 5430G0 And Is Intended For Use In Peugeot 407 Applications. Searching By These Product Codes In Parts Catalogs Or Diagnostic Outputs Will Help Confirm Fitment.
