Peugeot 307 Throttle Body Replacement Parts

Only petrol-engined 307s have a throttle body — diesel engines use a different fuelling system and do not have one, so if you have a diesel 307 (such as a 1.4 HDi, 1.6 HDi, or 2.0 HDi), a throttle body is not the part you need. Petrol variants, including the 1.4, 1.6, and 2.0 petrol engines, do use a throttle body as part of their fuel and air management system. If you have a diesel and are experiencing similar symptoms, you may be looking for an EGR valve or inlet manifold instead — confirm with your breaker what best matches your fault.

The Peugeot 307 ran from 2001 to 2008, with a facelift introduced in 2005, and while many mechanical components carried over across that boundary, the throttle body fitment is primarily driven by the engine code rather than the facelift year. If your pre-facelift and post-facelift cars share the same engine code — for example both are 1.6 petrol with the same code — there is a reasonable chance of compatibility, but ancillary mounting or connector changes can occur mid-production without obvious external differences. You should supply your engine code (found on your V5 or via a VIN check) and confirm cross-generation compatibility directly with the breaker before purchasing.

Engine code matters above everything else for a throttle body — two 307s both badged as 1.6 petrol can have different engine codes and use physically different throttle bodies with different connectors or bore sizes. The engine code is stamped on the engine block and also appears on your V5 logbook or a HPI/VIN check, and supplying it to the breaker is the single most useful thing you can do. Matching by year and engine size alone risks ordering the wrong unit, so always lead with the engine code.

Trim level makes no difference to throttle body fitment on the 307 — the S, LX, XT, and SW are all fitted with the same mechanical components for a given engine, and the throttle body is determined entirely by the engine code and fuel type. The SW (estate) body style shares the same engine range as the hatchback, so there is no functional difference there either. Buy on engine code, not on trim badge.

On most 307 petrol engines the throttle body itself is the same regardless of whether the car has a manual or automatic gearbox, as the unit is part of the engine's air intake system rather than the transmission. However, the engine management and mapping can differ between gearbox types, and there may be associated sensors or wiring differences to consider. Confirm with the breaker that the donor vehicle's gearbox type matches yours, particularly if there is any suggestion of ECU or sensor pairing involved.

Some 307 petrol throttle bodies are straightforward mechanical replacements, but on certain variants the throttle body position sensor or associated ECU calibration may require resetting or coding after fitting. Whether a specific used unit will be plug-and-play on your car depends on your exact engine code and the vehicle's management system, and this is not something that can be confirmed from the part alone. Raise this question directly with your breaker and factor in whether you will need a diagnostic session with a garage after fitting.
