Used Nissan Skyline Oxygen Sensor

Yes, all Nissan Skyline variants sold with petrol engines — including the R32, R33, R34, and R35 GT-R generations — use oxygen (lambda) sensors as part of their exhaust and engine management systems. The sensors sit in the exhaust system and feed the ECU data to control fuel mixture, so they are present on every fuel-injected petrol Skyline variant. If you have heard that Skylines don't have them, that is incorrect — confirm your exact generation and engine code with the breaker when sourcing a used one.

The R33 (1993–1998) and R34 (1998–2002) Skylines share the RB-series engine family, and some sensor configurations are similar, but the engine management systems and exhaust configurations differ between generations, meaning a direct swap is not guaranteed. What matters most is the engine code — for example, RB25DET to RB25DET — and the connector type and thread pitch, which can vary even within the RB family. Because this crosses a generation boundary, confirm the specific part number and connector compatibility with the breaker against your registration before buying.

No — trim level does not affect oxygen sensor fitment on the Skyline. What matters is the engine code (for example RB20DET, RB25DET, RB26DETT) and the model generation (R32, R33, R34, or R35), not whether the car is a base GT or a GT-R. Focus your search on matching those engine details rather than trim badges, and let the breaker verify the part against your registration.

Yes — the RB26DETT found in GT-R models and the RB25DET found in GTS-T and GT-R25 variants have different exhaust configurations, and the oxygen sensor placement, connector type, and calibration can differ between them. Always specify your engine code when asking a breaker for a used sensor, as sourcing an RB26DETT sensor for an RB25DET car (or vice versa) risks an incorrect fit or poor engine management performance. Confirm the full engine code and sensor position (pre-cat or post-cat) with the breaker before purchasing.

This is very unlikely to be a straightforward swap — the R35 GT-R (2007–present) uses an entirely different VR38DETT engine with a modern engine management system, and its oxygen sensors are designed around that platform rather than the older RB-series engines in the R34. The connectors, thread sizes, and sensor characteristics are almost certainly incompatible. Stick to sourcing a sensor from the correct RB-series generation and confirm the part with a breaker using your registration and engine code.

Yes — oxygen sensors are calibrated to work with the exhaust and engine management setup of a specific engine and era, so fitting a sensor from a significantly different emissions configuration could affect fuel mapping and potentially cause issues at MOT. For R32 to R34 Skylines sold in the UK as grey imports, emissions standards varied and there is no single Euro homologation boundary that applies neatly, so the engine code remains your most reliable guide to compatibility. Always tell the breaker your engine code and registration details so they can match the sensor correctly rather than relying on generation alone.
