Description
The Throttle Body for 1.6 HDi engines (PSA) with product codes 9660030380 and 0345E3 is a critical engine management component that controls air intake to the engine. This Delphi-style unit is commonly fitted to PSA diesel 1.6 HDi applications and is designed to restore correct idle, improve throttle response and eliminate driveability issues caused by a faulty or contaminated throttle body.
Why Choose This Throttle Body
- Direct-fit replacement for many Citroën and Peugeot 1.6 HDi models.
- Restores accurate air metering and idle control for smoother running and reduced stalling.
- Ideal for professional mechanics and competent DIY technicians who search by product code.
Fitment & Compatibility
Compatible with a range of PSA vehicles using the 1.6 HDi engine. Commonly fitted models include:
- Peugeot: 207, 307, 308
- Citroën: C3, C4, Berlingo
- Also used across other PSA variants equipped with the 1.6 HDi engine family — always verify by product code before purchase.
Symptoms Of A Faulty Throttle Body
- Unstable or fluctuating idle and frequent stalling at low speeds.
- Reduced throttle response and poor acceleration.
- Check Engine Light (CEL) related to throttle position or airflow faults.
- Rough running after cold start or excessive smoke during acceleration.
Common Causes And Service Notes
- Carbon and soot buildup on the throttle plate and bore impair movement and airflow — common on diesel engines.
- Worn sensors (potentiometer/position sensor) or stepper/electronic actuator failure can cause incorrect throttle positioning.
- Electrical connector corrosion, damaged wiring or vacuum leaks may mimic throttle body faults.
- There is no fixed replacement interval; inspect during routine services and at higher mileages (e.g., around 100,000 km) or when symptoms appear.
Replacement Guide (Overview)
Replacement is straightforward for a qualified mechanic or an experienced DIYer. Typical steps:
- Disconnect the negative battery terminal to prevent electrical faults.
- Remove intake ducting and airbox components to access the throttle body.
- Unplug the electrical connector and any vacuum lines attached to the unit.
- Remove the throttle body mounting bolts and carefully detach the unit, noting the gasket or seal condition.
- Fit the new throttle body with a new gasket, reconnect vacuum lines and the electrical connector, then reassemble intake components.
- Clear fault codes with a diagnostic tool and perform an idle relearn if required by the vehicle.
