Used Nissan NP300 Lambda Sensor

This depends entirely on the engine fitted. The NP300 Navara sold in the UK is predominantly diesel-powered, and diesel engines in this era typically do not use a traditional lambda (oxygen) sensor in the same way petrol engines do — instead they rely on a different set of exhaust sensors including NOx sensors and exhaust gas temperature sensors. If your NP300 has the 2.3-litre dCi diesel engine, it is very unlikely to have a conventional lambda sensor, so you may actually be looking for a NOx sensor, an exhaust gas temperature sensor, or a diesel particulate filter pressure sensor. Confirm which sensor is flagging a fault with your diagnostic code before ordering, and describe the fault code to the breaker so they can identify the correct part.

It is worth double-checking this, as traditional lambda (oxygen) sensors are primarily associated with petrol engines, not diesel ones. The 2.3 dCi diesel NP300 uses exhaust aftertreatment sensors suited to diesel emissions systems — such as NOx sensors or exhaust gas temperature (EGT) sensors — rather than a wideband lambda sensor in the conventional sense. If a parts catalogue or diagnostic tool has returned 'lambda sensor' as a description, it may be using that term loosely to refer to a NOx or oxygen-related sensor in the diesel exhaust system — take the exact OEM part number or fault code to the breaker to make sure you get the right component.

The NP300 Navara was introduced to the UK around 2016, with a mid-life update arriving around 2019 that brought emissions and specification changes. Exhaust sensors are closely tied to the engine management and emissions calibration of the specific build year, so a sensor from a pre-2019 vehicle may not be compatible with a post-2019 one even if it looks identical. You should confirm the exact engine code and build date of both the donor vehicle and your own with the breaker before purchasing, as fitting a sensor from the wrong emissions era can cause warning lights or MOT failures.

No, trim level does not affect which exhaust sensor is fitted — the Acenta, Tekna, N-Guard, and any other trim grade all share the same engine and exhaust system if they have the same engine code and are from the same build year. The differences between trims are cosmetic and equipment-based, not mechanical, so a sensor sourced from an Acenta is not inherently different from one sourced from a Tekna. What matters is matching the engine code and the build year, not the badge on the tailgate, so focus on those details when speaking to the breaker.

Give the breaker your full registration number so they can verify the exact build date and engine variant, and also provide any OEM part number or diagnostic fault code you have, as the description 'lambda sensor' can refer to different components depending on the system. The engine code (found on a sticker in the engine bay or on your V5C) and the model year are both important because exhaust sensor specifications can change across production runs. If a DPF or catalytic converter is also involved in the fault, treat any interchange questions about those parts as strong confirm-with-breaker territory, as fitment across different emissions configurations is not straightforward.
