The Nissan CR12DE is a 1,240 cc, inline‑three naturally aspirated petrol engine produced between 2002 and 2010. It features an aluminum block and head, dual overhead camshafts (DOHC), and 12 valves with multi — point fuel injection. This compact engine was engineered for efficiency and low emissions in Nissan's city car segment.
Fitted primarily to the Nissan Micra (K12) and Nissan Cube (Z11), the CR12DE was designed for urban agility and fuel economy. It offered adequat…
Production years 2002–2010 meet applicable Japanese and European emissions standards for their respective model years (VCA UK Type Approval data for imported models).
The Nissan CR12DE is a 1,240 cc inline‑three naturally aspirated petrol engine engineered for compact city cars (2002-2010). It combines a lightweight aluminum construction with DOHC valvetrain and multi-point fuel injection to deliver smooth, economical performance. Designed to meet the emissions standards of its era, it prioritizes low-end torque for city driving and ease of maintenance.

The Nissan CR12DE was used across Nissan's K12/Z11 platforms with transverse mounting. This engine received platform-specific adaptations-revised engine mounts for the Z11 Cube and different accessory brackets for the K12 Micra-creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The CR12DE's primary reliability risk is timing chain tensioner wear, with elevated incidence in high-mileage engines or those with poor maintenance. Nissan workshop data indicates this is a frequent cause of engine noise and potential failure in neglected engines, while owner reports often cite minor oil leaks as a secondary concern. Infrequent oil changes make adherence to the factory service schedule critical.
Analysis derived from Nissan technical bulletins (2003-2010) and aggregated owner workshop data (2002-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CR12DE is generally a reliable and economical engine. Its main weakness is the timing chain tensioner, which requires strict adherence to oil change intervals. With proper maintenance, including timely replacement of the tensioner if noisy, it can easily reach 200,000 km or more.
The most frequent issues are wear of the timing chain tensioner (causing noise), minor oil leaks from the valve cover gasket, ignition coil failures leading to misfires, and thermostat failures affecting engine temperature. These are well-documented in Nissan service bulletins.
The CR12DE was primarily used in the Nissan Micra (K12 generation, 2002-2010) and the Nissan Cube (Z11 generation, 2002-2008). It was the standard petrol engine for these compact models in many global markets.
Significant power gains are difficult due to its small displacement and naturally aspirated design. Minor improvements can be had from a free-flow air filter and exhaust, but gains are minimal. Forced induction is not a practical or cost-effective modification for this engine.
Fuel economy is excellent for city driving. Expect around 5.5–6.0 L/100km (51–47 mpg UK) in combined driving for a typical Micra. Its lightweight design and efficient combustion make it ideal for stop-start traffic and short commutes.
No. The CR12DE is a non-interference engine. If the timing chain fails or skips, the pistons will not contact the valves. This design makes it much more forgiving of timing component failures, though a broken chain will still leave you stranded.
Nissan recommends SAE 5W-30 synthetic or semi-synthetic oil. This specific viscosity is crucial for the proper operation of the hydraulic timing chain tensioner. Changing the oil and filter every 10,000–15,000 km is essential for engine longevity.
