Description
Connection cable + engine terminal for 2.0i vehicles for Peugeot 206 RC, 307 CC
This original-style connection cable and engine terminal assembly is intended for 2.0i Peugeot engines and is a practical replacement for workshops and DIY mechanics working on Peugeot 206 RC and Peugeot 307 CC. The part is commonly searched by product numbers (9645113380, 5642Y0) and is designed to restore reliable electrical connection in the engine bay where heat, vibration and contamination can degrade wiring and terminals over time. Ideal for replacing damaged or corroded connectors that cause intermittent faults, misfires or sensor communication errors.
Technical Information
- Manufacturer: Stellantis / Peugeot / Citroën
- Model: Peugeot 206 RC; Peugeot 307 CC
- Product Codes: 9645113380; 5642Y0; NFP
- Other Numbers: N/A
Function And Benefits
The cable and terminal ensure a secure electrical connection in the engine bay, transferring power or signal between engine components and the vehicle wiring loom. A correct, intact connection prevents intermittent faults, loss of sensor signals and poor engine performance. Benefits include restored continuity, improved contact reliability under thermal stress and simplified replacement compared with repairing individual wires.
Replacement Procedure
- Disconnect The Battery Negative Terminal To Avoid Short Circuits.
- Remove Any Engine Covers Or Components Obstructing Access To The Connector.
- Inspect The Existing Connector For Heat Damage, Corrosion Or Broken Clips.
- Release Retaining Clips And Unplug The Old Connector From The Mating Terminal.
- Route The New Cable Following The Original Harness Path And Secure With Existing Clips Or New Ties.
- Connect The New Terminal Firmly Until The Retaining Clip Clicks Into Place.
- Apply A Thin Layer Of Dielectric Grease To Pins If The Connector Is Exposed To Moisture (Optional).
- Reinstall Any Removed Covers, Reconnect The Battery And Start The Engine To Verify Proper Operation And That No Fault Codes Remain.
Installation Recommendations
- Always Work With The Battery Disconnected When Handling Engine Wiring.
- Check Wiring Routing To Avoid Contact With Hot Surfaces, Sharp Edges Or Moving Parts.
- Replace Any Damaged Clips Or Grommets To Prevent Chafing And Future Failures.
- Use Proper Tools For Connector Release To Avoid Breaking Plastic Tabs.
- After Installation, Clear Any Related Engine Fault Codes And Re-check After A Short Test Drive.
Why This Part Fails
Failures Are Typically Caused By Long-Term Exposure To High Engine Temperatures, Oil Or Coolant Leaks, Vibration-Induced Fatigue, Connector Corrosion And Physical Damage From Chafing Or Rodents. Plastic Clips And Insulation Harden Over Time, Which Leads To Cracked Sheathing Or Poor Contact Pressure In The Pins. Symptoms Often Include Intermittent Electrical Faults, Misfires, Relay Or Sensor Errors And Sometimes Visible Melting Or Corrosion On The Connector.
Service Life And Notes
The Lifespan Varies With Use And Environment; Many Assemblies Last The Life Of The Vehicle, While Others Fail Earlier on High-Mileage Cars or Vehicles Exposed To Leaks Or Severe Heat Cycles. Replacing A Faulty Connector Early Prevents Secondary Damage To Sensors Or Control Modules Caused By Poor Voltage Or Intermittent Signals.
For professional mechanics and competent DIYers, this cable assembly provides a direct and durable solution to restore reliable engine electrical connections on compatible 2.0i Peugeot models. Searchable by reference numbers 9645113380 and 5642Y0 for fast identification in parts catalogs.
