Nissan Pathfinder Fuel Injector Replacement Parts

Yes, fuel injectors are fitted to all Nissan Pathfinder variants sold in the UK – both the petrol and diesel engines use injectors, though the type differs significantly: petrol engines use port or direct fuel injectors, while the diesel engines (such as the 2.5 dCi found in the R51 generation) use high-pressure common-rail diesel injectors. Make sure you know your fuel type before sourcing, as a petrol injector and a diesel injector are entirely different components and are not interchangeable. The engine code on your V5 or a VIN check is the most reliable way to confirm exactly which injector specification you need.

Both years fall within the R51 generation (2005–2014), so there is a reasonable chance of compatibility if the engine codes match – for example, a 2.5 dCi YD25DDTi to a YD25DDTi. However, Nissan made running production changes during the R51's long life, and ancillary specifications or injector part numbers can vary mid-generation, so you should confirm the exact injector specification against your registration with the breaker before buying. Never assume year-to-year compatibility without cross-referencing the engine code.

The UK Pathfinder ran across two main generations relevant to most buyers: the R50 (1996–2004) and the R51 (2005–2014). These generations used entirely different engines and fuel systems, so a fuel injector from an R50-era engine will not cross over to an R51 and vice versa. If you are sourcing across that 2004–2005 boundary, treat the parts as incompatible and confirm everything with the breaker against your specific registration and engine code.

Trim level does not affect fuel injector fitment on the Nissan Pathfinder – the injector is determined by the engine code and fuel type, not whether the vehicle is a base S, mid-range SE, or top-specification Tekna. You may find cosmetic differences between vehicles stripped at a breaker's yard, but the injector itself is a mechanical engine component unaffected by trim designation. Focus entirely on matching the engine code and fuel type when sourcing your part.

The YD25DDTi 2.5 dCi engine was used across several Nissan models, and in some cases injectors may share the same part number, but you should not assume cross-model compatibility without verifying the engine code and injector specification carefully. Injection system calibration, rail pressure ratings, and connector types can vary even within the same engine family across different applications. Always provide your engine code and registration to the breaker so they can confirm compatibility before purchasing.

This is an important question, particularly for diesel common-rail injectors where individual injector trim codes or calibration data can be relevant to how the ECU manages fuelling. Whether a used injector requires coding or reprogramming to your vehicle's ECU is something you must confirm with the breaker and ideally your fitting garage, as this can vary by engine variant and production date. We cannot state this as fact either way – route this question to the breaker against your specific registration before committing to a purchase.
