Second Hand Nissan NV400 Lambda Sensor

The Nissan NV400 is powered exclusively by diesel engines, and lambda sensors are primarily an emissions management component associated with petrol engines; diesel engines of this type do not use a conventional lambda (oxygen) sensor in the same way. If your MOT or diagnostic report is flagging an exhaust-related sensor fault, you are most likely looking for a NOx sensor, a diesel particulate filter (DPF) pressure sensor, or an exhaust gas temperature (EGT) sensor, all of which do exist on NV400 diesel variants. Confirm exactly which sensor code or description your diagnostic tool is showing before ordering, as a breaker will need that detail to supply the correct part.

The NV400's 2.3-litre dCi diesel engine uses exhaust gas temperature (EGT) sensors, a diesel particulate filter differential pressure sensor, and on later Euro 6 variants a NOx sensor as part of the SCR (selective catalytic reduction) system. These are all engine and emissions-era specific, so a sensor from an early Euro 5 van (pre-2017 facelift era) may not physically or electronically match one from a Euro 6 example. Always confirm the exact sensor type, engine code, and registration year with the breaker before buying a used part.

Standard wideband or narrowband oxygen sensors as fitted to petrol vehicles are not a feature of the NV400's diesel drivetrain, so your garage may be using the term loosely to describe a related exhaust sensor such as an EGT or NOx sensor. Ask them to confirm the exact sensor name, its location on the exhaust (pre or post DPF, for example), and the fault code number, as this will make it far easier for a breaker to match a used part to your van. Providing your full registration to the breaker is also essential given the differences between Euro 5 and Euro 6 NV400 variants.

The NV400 received a significant update around 2017 which brought Euro 6 emissions compliance alongside changes to the exhaust aftertreatment system, meaning sensors from pre-2017 Euro 5 vans and post-2017 Euro 6 vans are unlikely to be interchangeable. Even within each era the engine code matters, so confirm the engine code on your donor vehicle matches your own before assuming compatibility. Route any specific cross-generation sensor interchange questions directly to the breaker with both registrations to hand.

Trim level does not affect the exhaust sensor specification on the NV400; what matters is the engine code, the model year, and the emissions standard (Euro 5 or Euro 6). An SE and a Sport van built in the same year with the same engine will use identical sensors, so you do not need to chase a trim-specific part. Focus your search on confirming the engine code and year with your breaker rather than the trim name.
