Peugeot 406 Throttle Body Replacement Parts

Only petrol-engined 406s have a throttle body — it is a core part of how a petrol engine controls airflow and fuelling. Diesel 406s (the common 1.9 TD, 2.0 HDi and 1.9 D units) do not use a throttle body in the conventional sense and never had one fitted. If you have a diesel 406 and are chasing a fuelling or airflow fault, you are most likely looking for something else entirely, such as an EGR valve or air mass meter — confirm the exact fault and engine code with a breaker before ordering anything.

The engine code is the single most important detail for this part — a throttle body is matched to the engine management system, not the badge or body style. Petrol 406s ran several engines including the 1.6, 1.8, and 2.0 units across the production run of 1995 to 2004, and different engine codes within those capacities can use different throttle body specifications. Check your V5 or run a VIN check to get your exact engine code, then supply that code to the breaker so they can match the part correctly. Never assume a 1.8 fits a 1.8 without confirming the codes match.

The 406 ran in its original form from 1995, with a significant facelift arriving in 1999 that brought styling and some mechanical updates. Whether the throttle body crosses that 1999 boundary depends entirely on whether your engine code remained the same across both production phases — if the code matches, fitment is much more likely. However, ancillary fittings, sensor connectors, and mounting details can change mid-production even on the same engine family, so you should confirm directly with the breaker against your specific registration rather than assume a pre-facelift unit will drop straight in.

Trim level has no bearing on throttle body fitment on the 406 — the LX, GLX, SR, and Executive badges describe interior and equipment levels, not engine specification. What matters is the engine code under the bonnet, which can be identical across multiple trim grades. You may find minor cosmetic differences in surrounding engine bay components depending on how the car was equipped, but the throttle body itself is determined by the engine, not the trim. Give the breaker your engine code and registration, and the trim name can be disregarded for this part.

Not necessarily, because the 406 2.0 petrol was available in different states of tune and with different engine management systems across the production years, meaning the throttle body specification could differ even within the 2.0 family. The engine code stamped on the block is the reliable guide here — two cars both badged 2.0 can have different codes and incompatible parts. Supply your full engine code to the breaker rather than relying on engine size alone, and ask them to verify the sensor connections and mounting pattern match before you commit to buying.

Body style makes no difference to throttle body fitment on the 406 — the saloon, estate (break), and coupe variants all used the same engines, and the throttle body is entirely determined by the engine code, not which body style it was bolted into. A part pulled from a 406 estate with the correct matching engine code is just as suitable as one from a saloon. Focus on confirming the engine code match with the breaker, and you can disregard which body style the donor car was.
