Description
Throttle body intake DELPHI for 1.4 HDI and 1.6 HDI 8V engines for Citroën, Peugeot, Ford, Volvo
This Delphi throttle body is intended for 1.4 HDI and 1.6 HDI (including e‑HDI variants) diesel engines fitted to a range of Citroën and Peugeot models and compatible Ford/Volvo applications. Supplied with OEM references 9673534480 and 0345G4, the unit restores correct air metering to the intake tract, improving idle stability, throttle response and overall drivability. The product description and codes make it easy to find when searching by part number — ideal for professional technicians and experienced DIYers.
Designed as a direct replacement for electronic (drive‑by‑wire) throttle systems on 8‑valve HDI engines, this throttle body works together with the engine management system to regulate airflow under all operating conditions. Typical benefits after replacement include reduced surging at idle, quicker throttle response and resolution of limp‑home symptoms caused by faulty position sensors or seized actuators.

Installation Recommendations
Before starting any work disconnect the negative battery terminal. Remove the intake hose and any obstructing components to access the throttle body. Disconnect the electrical connector and remove the mounting bolts. Inspect and replace the intake gasket where applicable, clean the mating surfaces, then fit the new throttle body and tighten fasteners to manufacturer torque settings. Reconnect all connectors and hoses.
After installation a throttle adaptation or idle relearn is usually required — either via a suitable diagnostic tool or by following the vehicle manufacturer’s specified procedure. It is recommended to clear related fault codes and verify live sensor values (throttle position, commanded vs actual) to confirm correct operation.
Why This Part Fails Most Often
- Carbon and soot buildup in the intake tract causing the throttle plate to stick or operate sluggishly.
- Wear or failure of the internal potentiometer/position sensor leading to incorrect position feedback.
- Actuator or stepper motor failure in the drive‑by‑wire mechanism.
- Electrical issues such as corroded connectors or damaged wiring harnesses.
- Ingress of oil, coolant or water in rare cases after intake system faults or collisions.
Because throttle issues often arise after long service intervals or from heavy EGR/intake contamination, inspect the intake, EGR valve and air filtration system when replacing the throttle body to reduce the risk of reoccurrence.
