Cheap Nissan Micra Throttle Body

Yes, petrol-engined Micras use a throttle body to regulate airflow into the engine, so this is a genuine and commonly replaced part on this model. Diesel variants were never offered in the Micra range sold in the UK, so every Micra you are likely to encounter runs a petrol engine with a conventional throttle body. If your Micra has an electronic throttle (drive-by-wire), the body contains a motor rather than a cable-operated butterfly, so make sure any used unit matches your engine type.

These are completely different generations with different engines and engine management systems, so a K11 throttle body will not straightforwardly swap onto a K12. The K11 used engines such as the CG10 and CG13, while the K12 moved to the CR10 and CR12 family, and the throttle bodies for these units differ in bore size, mounting pattern, and electrical connector. Always match the throttle body to the engine code on your V5 or a VIN check, not just the generation name.

The K12 Micra ran from 2003 to 2010 and received a facelift around 2007, but the core engine family — CR10 and CR12 — carried across that update without major mechanical revision to the throttle body specification. For most buyers the engine code will be the same on either side of the facelift, making the part interchangeable, but ancillary bracket positions or wiring loom connectors can sometimes change mid-production, so confirm with the breaker against your registration before purchasing.

Trim level does not affect throttle body fitment on the Micra — the Urbis, SVE, S, and other trim variants within the same generation all shared the same engine options, and it is the engine code that determines which throttle body you need, not the badge on the boot lid. A breaker may quote you a unit from a base-spec car that will suit a higher-trim example running the same engine without any issue. The only cosmetic difference you might notice is superficial corrosion or wear on a used unit, which does not affect function.

The K13 Micra introduced the HR12 engine (including the HR12DE and HR12DDR supercharged variant), which is a different unit from the CR-series engines in the K12, so the throttle bodies are not interchangeable between these generations. Give the breaker your engine code — found on your V5 or via a VIN check — and they can cross-reference it to confirm the correct unit. Note that if your K13 has the HR12DDR supercharged engine, the induction setup differs from a naturally aspirated HR12DE, so be specific about your variant when asking for quotes.

On drive-by-wire Micras the throttle body communicates with the ECU, and there is a possibility that the replacement unit may need a throttle position re-learn procedure using a diagnostic tool after fitting. Whether a used unit will operate correctly with your car's ECU without further coding is something you should confirm with the breaker or a Nissan-specialist mechanic against your specific registration, as this varies by engine and model year and we cannot guarantee it as a straightforward plug-and-play swap.
