Description
Intake Throttle Body Housing For Citroën And Peugeot Vehicles
This genuine-style intake throttle body housing is designed for a range of Citroën and Peugeot petrol engines. Ideal for professional workshops and competent DIY mechanics, the unit is commonly sought by part number (9640796280 / 1635R8) and restores correct air metering, throttle response and idle stability when the original housing is worn or contaminated.
Key Benefits
Reliable replacement for damaged or degraded intake throttle body housings. Improves drivability by restoring correct air flow, reduces rough idle and hesitation, and helps eliminate related fault codes. Straightforward fitment on compatible PSA/Stellantis engines makes this part a practical workshop repair item.

Compatibility And Application
Intended for petrol engines in the 1.8 16V and 2.0 16V families listed in the vehicle category. Always confirm engine type and part number before ordering; the part is most often searched by the OEM references 9640796280 and 1635R8.
Function
The throttle body housing provides the structural mount for the throttle plate and associated sensors/actuators that control the volume of air entering the intake manifold. Proper sealing and smooth operation are essential for accurate throttle response, stable idle and correct air/fuel ratio management by the engine control unit.
Why The Part Fails Most Often
- Carbon and oil deposits on the throttle plate and bore cause sticking or slow return, leading to rough idle and poor throttle response.
- Physical damage to the housing or mating flange from improper removal or impact.
- Degraded sealing surfaces or intake leaks at the throttle flange, causing unstable idle and vacuum-related faults.
- Contaminated or corroded electrical connectors (if the throttle assembly includes sensors/actuators), producing intermittent faults or loss of signal.
Installation Recommendations
Recommended for installation by a qualified mechanic or an experienced DIYer with basic workshop tools. Basic replacement steps:
- Disconnect the battery before starting work to avoid short circuits and ensure safety.
- Remove the air inlet tract and any engine covers to access the throttle body.
- Disconnect electrical connectors and vacuum lines carefully; mark hoses for correct reassembly.
- Unbolt the throttle body housing from the intake manifold, remove the old gasket and clean the mating surface thoroughly.
- Fit the new housing with a correct gasket or seal, reconnect sensors and hoses, and reassemble the intake tract.
- Do not overtighten fasteners; follow the vehicle manufacturer torque recommendations where available.
- After installation, clear any stored fault codes and perform the throttle/idle relearn procedure as specified by the vehicle manufacturer to ensure correct idle and response.
Notes For Professionals
When replacing only the housing, inspect and, if necessary, clean or replace the throttle plate, shaft seals and position sensor to avoid recurrent faults. Check for intake leaks and vacuum hoses that may have contributed to the original failure. For vehicles with electronic throttle control, verify connector integrity and wiring harness condition during installation.
