Description
Throttle valve, throttle body housing for 2.0 HDi RHR 100 kW engines.
This OEM-style throttle body assembly is designed for PSA Group 2.0 HDi RHR 100 kW engines and is commonly searched by part numbers 9684269380, 0345F0 or 0345E9. Built to control intake airflow precisely, the unit restores accurate throttle response and stable idle when installed as a direct replacement for worn or faulty throttle bodies. Ideal for professional workshops and skilled DIY mechanics, the component fits into the intake tract and works with the engine management system to regulate air volume depending on driver demand.

Function And Benefits
The throttle body regulates the amount of air entering the engine, directly affecting throttle response, idle stability and fuel/air mixture control. On electronic throttle systems it contains sensors and an actuator that communicate with the ECU to provide precise, drive-by-wire control. Replacing a faulty throttle body eliminates erratic idling, limp-home behavior and throttle hesitation caused by malfunctioning sensors or a jammed plate.
Why This Part Fails Most Often
- Carbon and soot buildup on the throttle plate and bore causing sticking or incorrect airflow readings.
- Failure of the throttle position sensor or electronic actuator due to wear or moisture ingress.
- Corroded or damaged electrical connector and wiring causing intermittent signals.
- Vacuum leaks or intake tract contamination that affect operation and sensor readings.
Installation Recommendations
- Always Disconnect The Battery Before Starting Work To Prevent Electrical Damage.
- Remove Intake Hosework And Airbox To Access The Throttle Body. Unplug The Electrical Connector And Any Vacuum Lines.
- Unbolt The Throttle Body From The Intake Manifold, Replace The Gasket, And Ensure All Mating Surfaces Are Clean.
- Reinstall Using Manufacturer Torque Specifications For Fasteners And Reconnect All Lines And Connectors Securely.
- After Installation, Perform Throttle Body Adaptation/Initialization With A Diagnostic Tool (DiagBox/Lexia/PP2000 Or Equivalent) To Ensure Correct Idle And Throttle Response.
- Always Use Quality Gaskets And Avoid Over-Tightening Fasteners To Prevent Warping Or Air Leaks.
Replacement Procedure (Brief)
- Park Vehicle On A Level Surface, Engage Handbrake, And Disconnect Negative Battery Terminal.
- Remove Air Intake Components To Gain Access To The Throttle Body.
- Disconnect Electrical Connector And Vacuum Lines; Mark Them If Necessary For Correct Reassembly.
- Unfasten Mounting Bolts, Remove The Old Throttle Body And Clean The Intake Flange.
- Fit New Throttle Body With A New Gasket, Torque Bolts To Manufacturer Specification, Reconnect Lines And Connectors.
- Reconnect Battery, Clear Any Engine Fault Codes, Perform Throttle Adaptation, And Road Test To Confirm Proper Operation.
Notes For Mechanics And DIY Enthusiasts
Searches For This Part Are Often Performed Using The OE Numbers Listed Above, So Including Those Codes In Your Order Or Workshop Notes Speeds Up Identification. While experienced DIYers Can Perform The Mechanical Swap, Calibration With A Suitable Diagnostic Tool Ensures Reliable Operation—otherwise idle irregularities or fault codes may persist. Regular Intake Cleaning And Proper EGR Maintenance Help Extend Throttle Body Service Life.
