Nissan Pathfinder Lambda Sensor Replacement Parts

Yes, but only on petrol-engined variants — the R51 Pathfinder (2005–2014) was sold in the UK predominantly with a 2.5 dCi diesel engine, which does not use a lambda (oxygen) sensor in the traditional sense; diesel engines use different exhaust gas management and do not have lambda sensors. If your Pathfinder is the 2.5 dCi diesel, you are likely looking for something else — possibly an EGR valve, NOx sensor, or exhaust temperature sensor. The petrol V6 variants (sold in some markets) do carry lambda sensors upstream and downstream of the catalytic converter, but these were rare in the UK market, so confirm with the breaker that your specific registration actually has a petrol engine before ordering.

The 2.5 dCi diesel does not use a lambda sensor, so if you are chasing an exhaust or emissions-related fault, the part you need is more likely an EGR valve, a diesel oxidation catalyst temperature sensor, or a NOx/exhaust gas sensor depending on the fault code. Give the breaker your registration and the exact fault code from your diagnostic scan so they can identify the correct sensor for your engine. Fitting a lambda sensor to a diesel Pathfinder is not applicable and will not resolve a diesel emissions fault.

For the petrol-engined variants where lambda sensors do apply, trim level does not affect sensor fitment — what matters is the engine code and the emissions standard (Euro rating) the vehicle was built to, not whether the car is an S, SE, or SVE. A used sensor from the same engine and emissions era should be compatible regardless of trim, though cosmetic differences in surrounding heat shielding or loom routing may occasionally be present. Always confirm the engine code and registration with the breaker rather than relying on trim name alone.

The R51 Pathfinder ran from 2005 to 2014, with a facelift arriving around 2010. For the rare UK-market petrol V6 variants, the lambda sensor fitment is tied to the engine code and emissions calibration rather than the facelift bodywork changes, but the 2010 facelift period can coincide with emissions standard updates that affect sensor specification. This is strong confirm-with-breaker territory — give the breaker both the donor vehicle's registration and your own so they can cross-reference engine codes and Euro emission levels before you commit to a part.

Nissan does share engine families across models, and a lambda sensor from another Nissan with the same petrol engine code and identical emissions calibration may physically interchange, but exhaust system routing, connector type, and cable length can differ even between related vehicles. Rather than guessing by model name, give the breaker your Pathfinder's engine code and they can check whether a sensor from their stock — whatever the donor vehicle — is a genuine match. Never assume compatibility on body style or brand alone.

In the UK, the vast majority of Pathfinders were sold with the 2.5 dCi diesel engine, which does not use lambda sensors, so there is very little breaker stock of Pathfinder lambda sensors and limited garage familiarity with fitting them to this model. If your vehicle is confirmed as a petrol variant, a specialist breaker who can search by engine code across the Nissan range is your best route, as the sensor may be listed under a related Nissan model rather than Pathfinder specifically. If your vehicle is diesel, your garage may have confused the fault code with a lambda-type sensor — ask them to recheck the diagnostic output against the correct diesel sensor type.
