Second Hand Nissan NV400 Oxygen Sensor

The Nissan NV400 is powered exclusively by diesel engines across all variants, and diesel engines do not use oxygen sensors in the way petrol engines do — they rely on different emissions management systems including a DPF and EGR rather than a lambda/O2 sensor feeding a closed-loop fuelling system. If you are looking for an emissions-related sensor on your NV400, you are most likely after a NOx sensor, a differential pressure sensor (DPF pressure sensor), or an EGR-related sensor instead. Confirm the exact sensor you need with a breaker by providing your registration, as they can identify the correct part from the vehicle's spec.

It is very likely a misidentification or a loose use of the term — on a diesel NV400 there is no conventional oxygen (lambda) sensor, so a parts supplier using that label is probably referring to a NOx sensor or a DPF differential pressure sensor, both of which monitor exhaust gases in a broadly similar role. NOx sensors in particular are sometimes informally called oxygen sensors by non-specialist sellers. Give your registration to the breaker and ask them to confirm the exact sensor by its position in the exhaust system and its OEM part number before purchasing.

Depending on the model year and engine variant, the NV400 diesel can carry a DPF differential pressure sensor, a NOx sensor (particularly on Euro 5 and Euro 6 vehicles), EGR temperature sensors, and exhaust gas temperature sensors at various points in the system. The Euro 6 variants introduced stricter NOx controls and may have additional sensors compared to earlier Euro 5 models, so the exact sensors fitted depend on the engine code and emissions standard of your specific vehicle. Always confirm against your registration with the breaker, as sensor specification can vary between engine codes even within the same model year.

The NV400 received a facelift around 2014, and while the underpinning engines are closely related across the range, the emissions equipment was updated over the model's life as Euro 5 and later Euro 6 standards came into effect — meaning exhaust and emissions sensors from an early pre-facelift van are not guaranteed to be compatible with a later model. Engine code and emissions era are the critical factors here, not the facelift styling changes. Confirm any sensor interchange across the 2014 boundary directly with the breaker using both vehicles' registrations.

No, trim level does not affect the emissions sensors fitted to the NV400 — these are determined entirely by the engine code and the emissions standard (Euro 5 or Euro 6) the vehicle was built to, not by whether it is an SE, Sport, or higher-grade variant. You may find differences in comfort or technology features between trims, but the exhaust and emissions sensor specification will be the same across trims sharing the same engine and model year. Focus on your engine code and registration when sourcing any sensor from a breaker.
