Used Nissan NP300 Throttle Body

The Nissan NP300 Navara sold in the UK is diesel-only, and diesel engines do not use a throttle body in the same way a petrol engine does — they control power through fuel quantity rather than air restriction via a throttle butterfly. What you may actually be looking for is the EGR valve, the swirl flap motor, the intake manifold control actuator, or the diesel throttle/intake flap assembly, all of which are fitted to various NP300 diesel engines and are sometimes loosely called a 'throttle body' by sellers. If you're chasing an airflow or idle-control fault, tell the breaker your exact engine code (visible on your V5 or via a VIN check) and they can identify the correct component.

On the NP300 Navara's diesel engines, the part most commonly confused with a throttle body is the intake throttle valve or swirl flap actuator, which sits in the intake tract and helps manage EGR flow and engine braking — it can cause similar symptoms to a failed petrol throttle body, such as poor idle or limp mode. Another common culprit is the EGR valve itself, or the EGR cooler on higher-mileage engines. Quote your engine code to the breaker rather than searching by part name, as the same assembly goes by several different names across different listings.

On a diesel NP300 Navara, fault codes relating to 'throttle position' or 'throttle body' usually point to the intake throttle valve or swirl flap assembly rather than a traditional petrol-style throttle body, which this engine does not have. The fault code description can be misleading because generic OBD software borrows petrol terminology. It is worth having the fault properly diagnosed and your engine code confirmed before ordering any parts, so you can describe the exact component accurately to the breaker.

No — body style makes no difference to drivetrain components on the NP300 Navara; the engine and its associated intake components are the same regardless of whether the truck is a King Cab or Double Cab. What matters is your engine code, which you can find on your V5 logbook or via a HPI/VIN check. Always quote the engine code to the breaker so they can pull the right part from the correct donor vehicle.

The NP300 Navara received a mid-life update around 2019, which brought changes to the engine management and emissions systems, so intake components from an early NP300 (roughly 2016–2019) may not be a straightforward swap onto a later facelift model even if the engine code appears the same. You should confirm with the breaker whether the specific part number matches your registration, as ancillary and mounting details can change mid-production without a full engine code change. Always provide your full registration or VIN rather than just the year when asking a breaker to source intake components.
