The Honda N22A2 is a 2,199 cc, inline‑four naturally aspirated petrol engine produced between 2009 and 2015. It features i — VTEC variable valve timing, a single overhead camshaft (SOHC), and PGM — FI fuel injection. This engine delivers 110 kW (150 PS) and 206 Nm of torque, with i — VTEC enabling a broad, flat torque curve for responsive everyday drivability.
Fitted primarily to the fourth — generation Honda CR — V (RE) for European and global markets, the N22A2 was engineered…

Production years 2009–2015 meet Euro 5 standards for all applicable markets .
The Honda N22A2 is a 2,199 cc inline‑four naturally aspirated petrol engine engineered for compact SUVs (2009-2015). It combines i-VTEC variable valve timing with PGM-FI fuel injection to deliver smooth, linear power delivery and strong low-end torque. Designed to meet Euro 5 standards, it balances urban agility with highway cruising capability.

The Honda N22A2 was used across Honda's Global SUV platform with transverse mounting. This engine received platform-specific adaptations-unique engine mounts for the CR-V-creating minor service part variations. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from Honda technical bulletins (2011-2014) and aggregated owner-reported failure data (2010-2023). 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 N22A2 is generally robust, but early engines (pre-2012) are susceptible to exhaust camshaft lobe wear, leading to performance issues. Later models and those repaired per SIB A13-008 are very reliable. Regular oil changes with the correct specification are paramount for longevity, especially for vehicles used for towing or spirited driving.
The most documented issues are premature exhaust camshaft lobe wear, VTC actuator rattle on cold starts, PCV valve clogging causing oil leaks, and coolant leaks from the thermostat housing. These are covered in Honda service bulletins and widely reported in technical forums.
The N22A2 was used exclusively in the fourth-generation Honda CR-V (RE, 2009-2015) for European and global markets. It was not used in North American or Japanese Domestic Market (JDM) vehicles, which received different engine variants like the K24.
Tuning potential is limited due to its naturally aspirated, SOHC design. ECU remaps can yield minor gains (5-10 kW) by optimizing ignition and fuel curves. Significant power increases require forced induction, which is complex and costly. Most owners focus on maintenance for reliability rather than performance upgrades.
Good for its class and era. In the Honda CR-V, expect ~9.0 L/100km (city) and ~6.5 L/100km (highway), or about 31 mpg UK combined. Real-world figures are highly dependent on driving style, vehicle condition, and terrain.
Yes. The N22A2 is an interference engine. If the timing chain were to fail (an extremely rare event), the pistons would collide with the open valves, causing catastrophic internal damage. Fortunately, the timing chain is designed to last the engine's lifetime with proper oil maintenance.
Honda recommends 5W-30 synthetic oil for optimal protection, especially in varied climates. 0W-20 is also acceptable for improved fuel economy. The oil must meet API SN/RC or ACEA A5/B5 specifications. Changing oil every 10,000 km or 12 months is critical to prevent camshaft and VTC actuator issues.
