Description
Overview
The Delphi intake throttle valve for 1.4 HDi PSA engines controls intake airflow to stabilise idle and support EGR management. Although diesel engines do not use a traditional throttle for power control, this valve is essential for emission control and smooth idling.
Key Features
- Direct-fit replacement for many 1.4 HDi applications
- OEM/Delphi quality electronic throttle unit
- Restores idle stability and helps EGR operation
- Easy electrical connector and bolt-on installation
Fitment And Compatible Models
Commonly fits PSA 1.4 HDi models including, but not limited to:
- Peugeot 206, 207, 307
- Citroën C2, C3, C3 Pluriel
- Some Ford models that use PSA 1.4 HDi engines
Always check the part number (9656113080 / 1628XZ) against your vehicle before ordering.
Replacement & Installation
- Disconnect the negative battery terminal to avoid electrical faults.
- Remove the air intake hose and airbox to access the throttle valve on the intake manifold.
- Unplug the electrical connector and remove mounting bolts.
- Replace the old valve, fit a new gasket if required, and tighten bolts to manufacturer recommendations.
- Reconnect the electrical connector and battery, then perform throttle adaptation/idle relearn if required by the vehicle.
Common Failures And Lifespan
Typical failure causes include carbon build-up, faulty position sensor or potentiometer, wiring/connectivity issues, and contamination from EGR flow. Lifespan varies with driving conditions; many units show issues after 100,000 km but this depends on maintenance and EGR condition.
