Used Nissan Almera Oxygen Sensor

Yes, all petrol-engined Nissan Almeras have at least one oxygen sensor (also called a lambda sensor), which sits in the exhaust system and helps the ECU manage the fuel mixture. The N15 generation (1995–2000) and N16 generation (2000–2006) both carried them on their petrol variants. Diesel Almeras do not use an oxygen sensor in the same way, so if you have a diesel model you are unlikely to need one — confirm with a breaker what your exact engine requires.

Both years fall within the N16 generation (2000–2006), so fitment is more likely to be compatible provided the engine codes match — the key thing to cross-reference is the engine code stamped on your car, not just the year. The N16 received a facelift around 2003 but this did not fundamentally change the engine range or exhaust layout. Give your registration to the breaker and ask them to match on engine code to be sure.

The N15 and N16 are distinct generations with different engine families, so an oxygen sensor from an N15 crossing into an N16 application — or vice versa — is not a straightforward swap and should not be assumed compatible. Name the boundary and treat it with caution: confirm the engine code on both donor and recipient vehicles with the breaker before buying. A sensor that physically fits the thread may still have the wrong number of wires or calibration for the ECU of the other generation.

No, trim level does not affect oxygen sensor fitment on the Almera — the E, S, SE, and SVE badges describe interior and equipment differences, not changes to the engine or exhaust system. What matters is your engine code and fuel type, not which trim you have. Two Almeras of the same year and engine code will use the same sensor regardless of trim, so focus on matching those details rather than the badge on the bootlid.

Petrol Almeras typically have a sensor upstream of the catalytic converter (pre-cat) and, depending on the engine variant and emissions standard of that particular year, possibly a second downstream sensor (post-cat) as well. The exact number can vary by engine code and whether the car was built to a specific emissions calibration, so it is worth confirming the sensor position — upstream or downstream — before ordering from a breaker. Buying the wrong position sensor is a common mistake, even when the part number looks similar.

Engine displacement alone is not enough to guarantee fitment; you need to match the specific engine code, as different versions of the 1.5-litre unit can have different sensor connectors, thread sizes, or wiring configurations. Provide your registration number to the breaker so they can identify the exact engine code and confirm the sensor they have on the shelf came from a compatible donor car. Never assume that two cars sharing the same quoted engine size use interchangeable sensors without that code-level check.
