Second Hand Nissan Cabstar Oxygen Sensor

The Nissan Cabstar is a light commercial truck that has been sold in the UK powered exclusively by diesel engines across all its generations, and diesel engines do not use oxygen sensors (lambda sensors) in the same way petrol engines do. Diesel exhaust systems may include NOx sensors or exhaust gas temperature sensors, but a traditional wideband or narrowband oxygen sensor is not a standard fitment on any diesel Cabstar variant. If your diagnostic code is pointing to an exhaust gas sensor fault, you are most likely looking for a NOx sensor, an exhaust gas temperature (EGT) sensor, or possibly a sensor associated with the DPF or SCR system depending on your vehicle's emissions era. Confirm the exact sensor type and part number with a breaker against your registration to make sure you source the correct component.

On a diesel Cabstar, what is commonly referred to in fault codes as an 'oxygen' or 'O2' related sensor is almost certainly either a NOx sensor (used on later Euro 5 and Euro 6 compliant trucks with SCR systems) or an exhaust gas temperature sensor, rather than a traditional lambda-style oxygen sensor. The specific sensor you need will depend on your Cabstar's engine code and emissions standard, so check the exact fault code and cross-reference the part number before approaching a breaker. Sourcing the wrong sensor type is easy to do when descriptions online blur these terms together, so being precise will save time and money.

Yes, the generation and emissions era of your Cabstar makes a significant difference to the exhaust sensor configuration. Later trucks built to Euro 5 and Euro 6 standards are fitted with more complex after-treatment systems including DPF and SCR technology, which bring additional sensors such as NOx sensors and multiple exhaust gas temperature sensors that earlier trucks simply did not have. Whether a sensor from one emissions era crosses over to another is strong confirm-with-breaker territory - name your registration and engine code to the breaker so they can match the correct part.

No, the body configuration, payload rating, or cab style of your Cabstar does not affect which exhaust sensors are fitted to the vehicle. Fitment is determined entirely by the engine code and the emissions standard the truck was built to, not by whether it is a tipper, dropside, or box body. Focus on confirming your engine code and registration year when speaking to a breaker.

Nissan has used shared platforms and engines across its light commercial range, so there is a possibility of crossover with other models, but this is not something to assume without verification. Sensor connectors, calibrations, and mounting positions can differ even between visually similar parts, and fitting the wrong sensor could cause ongoing fault codes or affect emissions compliance at MOT. Always quote your Cabstar's registration, engine code, and the exact OEM part number to the breaker rather than relying on a physical match alone.
