Description
Throttle Body (Intake) Delphi For 1.4 HDi And 1.6 HDi 8V Engines For Citroën, Peugeot, Ford, Volvo. Assembled Air Dosing Unit
High-quality Delphi throttle body designed for 1.4 HDi and 1.6 HDi 8V engines used on a range of Citroën and Peugeot models (also fitted to some Ford and Volvo applications). Supplied under OEM cross-reference numbers 9673534480 / 0345G4, this assembled air-dosing unit controls the amount of intake air and works with the engine management system to ensure stable idle, smooth throttle response and correct emissions. Ideal for professional workshops and DIY mechanics who need a direct-fit replacement part that restores proper airflow control and eliminates drivability issues caused by a failing throttle body.
Applications
Fits engines: 1.4 HDi, 1.6 HDi 8V. Typical vehicle applications include (examples): Citroën Berlingo B9, Citroën C3 Picasso, Citroën C4 (including C4 II and C4 Picasso), Peugeot 3008 I, Peugeot 308, Peugeot 5008 I, Peugeot Partner Tepee. Also used on certain Ford and Volvo diesel platforms where the Delphi unit is specified. Always verify part numbers against the vehicle’s fitted unit before installation.
Technical Information
- Manufacturer: Delphi
- Model: For 1.4 HDi and 1.6 HDi 8V Engines (Citroën / Peugeot / Selected Ford & Volvo)
- Product Codes: 9673534480, 0345G4, 0345.G4
- Other Numbers: Associated Fault Codes: P0487, P0490, P2142, P2143
Function And Symptoms Of Failure
The throttle body meters incoming air to the engine and provides the correct idle control signal to the ECU. Modern units combine the throttle plate with an electronic actuator and position sensor. Common symptoms of a failing throttle body include irregular idle, stalling, limp-home mode, poor throttle response, reduced fuel economy and illumination of the engine management lamp with related fault codes.
Why The Part Fails Most Often
- Carbon Build-Up: Soot and oil residues from the EGR and crankcase ventilation accumulate on the throttle plate and bore, obstructing movement and position sensing.
- Wear Of Actuator/Sensor: Internal stepper motor or potentiometer faults impair accurate throttle positioning.
- Electrical Issues: Corroded connectors, damaged wiring or intermittent contacts cause loss of signal to the ECU.
- Vacuum Or Intake Leaks: External leaks cause incorrect airflow measurements and erratic idle control.
Recommended Installation
- Disconnect Battery Before Starting Work To Avoid Electrical Damage And Unwanted Faults.
- Remove Intake Ducting And Engine Covers To Access The Throttle Body.
- Unplug Electrical Connectors And Any Vacuum Hoses Attached To The Unit.
- Unbolt Throttle Body From Intake Manifold, Remove Old Gasket And Clean Mating Surfaces.
- Fit New Throttle Body With A New Gasket/Seal; Tighten Fasteners To Manufacturer Torque Specifications.
- Reconnect Hoses And Electrical Connections; Refit Intake Ducting.
- Perform Throttle Adaptation/Relearn Using PSA Diagnostic Tool (DiagBox/Lexia/PP2000) Or Follow Vehicle-Specific Relearn Procedure To Ensure Proper Idle And Throttle Response.
- Inspect Intake And EGR System For Carbon Deposits; Clean As Needed To Prevent Rapid Recontamination.
Maintenance Advice
Inspect And Clean The Throttle Body During Major Services Or If You Experience Idle/Response Issues. For diesel HDi engines, consider checking and cleaning the intake tract and EGR system every 60,000–80,000 km to reduce carbon-related faults. Replace The Gasket Whenever The Unit Is Replaced.
Compatibility And Codes
This unit is commonly referenced by codes 9673534480 and 0345G4 (also seen as 0345.G4). Fault codes often associated with throttle or idle control issues include P0487, P0490, P2142 and P2143. Use These Numbers When Searching For Replacement Parts Or Diagnostics.
Notes For Professionals
Designed For Direct Replacement On Vehicles Specified Above. For Best Results Fitment And Reprogramming Should Be Performed By A Technician Familiar With PSA Diesel Systems; Incorrect Installation Or Missing Adaptation May Trigger Faults Or Degraded Driveability.
