Description
Throttle Valve, Intake Throttle Body Housing
For Engines 1.4 16V VTI and 1.4 KFT
High-quality throttle body designed for Citroën and Peugeot 1.4 petrol engines. This intake throttle valve and housing assembly (OE references 9685879480 / 163667) restores correct air metering, smooth idle control and throttle response. Ideal for professional workshops and DIY mechanics who search by part number. Replacing a worn or faulty throttle body returns drivability, reduces rough idle and can eliminate limp-home behaviour caused by throttle position faults or excessive carbon buildup.

Function And Application
The throttle body controls airflow into the engine intake; it is a key component of the engine management system responsible for idle regulation and throttle response. On modern 1.4 16V VTI / 1.4 KFT engines it is typically an electronic throttle assembly with an integrated position sensor and actuator. Correct operation ensures stable idle, accurate load sensing and proper fuel/air mixture control.
Fitment And Compatibility
Fits the specified 1.4 petrol engines across listed Citroën and Peugeot models. Always check the part number printed on the unit or referenced in service documentation when matching to the vehicle. Commonly searched using OE numbers 9685879480 and 163667.
Installation Recommendations
- Disconnect the battery before starting work and follow the vehicle manufacturer’s safety procedures.
- Remove the air intake hose and any sensors or vacuum lines attached to the throttle body.
- Unplug the electrical connector carefully to avoid connector damage.
- Undo the throttle body mounting bolts and remove the unit together with the gasket or sealing ring.
- Clean mating surfaces on the intake manifold and fit a new gasket; do not reuse old gaskets.
- Refit bolts and tighten to the manufacturer’s torque specification (refer to factory manual for exact values).
- After installation, perform throttle adaptation/idle relearn using a diagnostic tool (or follow the manufacturer’s relearn procedure) to ensure correct idle and throttle response.
- Inspect electrical connections and vacuum lines for corrosion or damage before reassembly.
Why This Part Commonly Fails
- Carbon and oil deposits in the intake tract cause the throttle plate to stick or move sluggishly, affecting idle and response.
- Wear or failure of the integrated position sensor or actuator motor leads to incorrect throttle position readings and limp-home modes.
- Contaminated or corroded electrical connectors and wiring can cause intermittent faults or loss of signal.
- Vacuum leaks at the throttle body gasket or intake manifold affect idle stability and engine performance.
Order by OEM part number (9685879480 / 163667) for quick identification. Suitable for workshops and self-repair enthusiasts who want a reliable replacement throttle body for Citroën and Peugeot 1.4 petrol engines.
