Description
Intake Throttle Valve For 2.0 HDi RHR Engines For Citroën And Peugeot
This throttle body is intended for 2.0 HDi RHR engines used in various Citroën and Peugeot models. It controls airflow to the intake manifold and works with the engine management system to regulate idle, throttle response and emissions. The unit is supplied with OE-equivalent product codes commonly used when ordering replacement parts.
Key Features And Benefits
- Direct fit for 2.0 HDi RHR diesel engines—maintains correct air metering and engine response.
- Electronic Control Compatible—designed to interface with the vehicle’s engine control system for precise throttle positioning.
- Improves Idle Stability And Driveability—replaces worn or erratic throttle bodies that cause surging, stalling or limp-home mode.
- Suitable For Professional Workshops And Experienced DIYers—OE codes included for quick identification and ordering.
Compatibility
Common Applications (Non-Exhaustive):
- Citroën C4 Picasso
- Citroën C5
- Citroën C5 X7
- Citroën C8
- Peugeot 407
- Peugeot 807
Installation
- Park On A Level Surface And Allow The Engine To Cool.
- Disconnect The Negative Battery Terminal Before Starting Work To Prevent Short Circuits And Fault Codes.
- Remove Air Intake Ducting And Any Sensors Or Vacuum Lines Obstructing Access To The Throttle Body. Mark Or Photograph Connectors For Correct Reassembly.
- Unplug Electrical Connector(s) And Unscrew The Throttle Body Fasteners. Remove The Unit Carefully To Avoid Damaging The Throttle Plate Or Sensor Elements.
- Clean Mating Surfaces And Replace The Throttle Body Gasket If Required. Fit The New Unit And Tighten Fasteners To The Manufacturer’s Torque Specifications.
- Reconnect All Hoses And Connectors. Refit Intake Ducting.
- Reconnect The Battery, Then Perform Throttle Adaptation/Initialization Using An Appropriate Diagnostic Tool Or Follow The Manufacturer’s Relearn Procedure To Ensure Correct Idle And Response.
Installation Recommendations
- Always Replace The Gasket Or Seal When Installing A New Throttle Body.
- Inspect And Clean Intake Hosework And MAF Sensor To Prevent Recurrence Of Carbon Contamination.
- Use A Diagnostic Tool To Clear Fault Codes And Perform Throttle Learning; If No Tool Is Available, Follow The Vehicle Manufacturer’s Relearn Procedure (Ignition Cycles/Idle Steps) Where Applicable.
- Avoid Forcing The Throttle Plate When Handling The Unit; Handle Electrical Connectors Carefully To Prevent Bent Pins Or Corrosion.
Why The Part Most Commonly Fails
- Carbon And Soot Buildup On The Throttle Plate And Bore—Especially Common On Diesel Engines With EGR Circuits—Leads To Sticking, Erratic Idle And Reduced Airflow.
- Wear Or Failure Of Internal Position Sensors Or Actuator Motor Causes Incorrect Throttle Position Feedback And Triggers Limp Modes Or Fault Codes.
- Electrical Connector Corrosion Or Damaged Wiring Results In Intermittent Communication With The Engine Control Unit.
- Physical Damage From Improper Cleaning Or Impact During Service.
