Production years 2015–Present meet Euro 6 standards and equivalent global emissions regulations (Toyota Emissions Certification TEC-15-2NR).
The Toyota 2NR-FKE is a 1,496 cc inline‑four direct injection petrol engine engineered for subcompact hatchbacks and MPVs (2015-Present). It combines Atkinson cycle operation with VVT-iW technology to deliver exceptional fuel efficiency and smooth, linear power delivery. Designed to meet Euro 6 and equivalent global standards, it prioritises low emissions and running costs over ultimate performance.

The Toyota 2NR-FKE was used across Toyota's XP/NSP platforms with transverse mounting. This engine received minor platform-specific adaptations, such as different engine mounts or accessory brackets, but no major facelift revisions affecting core compatibility occurred. 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 2NR-FKE's primary reliability consideration is intake valve carbon buildup, a common trait of GDI engines, with elevated incidence in vehicles subjected to frequent short trips. Toyota service data indicates this is a maintenance item rather than a failure, while owner reports frequently cite sensitivity to oil viscosity as a common operational issue. Extended oil change intervals and use of incorrect oil specification can exacerbate VVT-iW system wear.
Analysis derived from Toyota technical bulletins (2015-Present) and aggregated owner workshop reports (2016-2023). 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
Yes, the 2NR-FKE is generally very reliable with proper maintenance. Its chain-driven design eliminates timing belt concerns. The main considerations are managing intake valve carbon buildup through periodic cleaning and using the correct 0W-20 oil to protect the VVT-iW system. With these addressed, it is a durable and economical engine.
The most frequent issues are carbon buildup on the intake valves (common to all GDI engines), potential wear of the VVT-iW actuator if incorrect oil is used, and failure of the high-pressure fuel pump or electronic thermostat on high-mileage examples. These are well-documented in Toyota service literature.
The 2NR-FKE is primarily used in the fourth-generation Yaris (XP150, 2015-Present), the third-generation Vios (XP150, 2016-Present), and the second-generation Sienta (NP170, 2015-Present) in various global markets, particularly in Asia and Europe.
Significant power gains are difficult due to the engine's focus on efficiency and its high compression ratio. Minor improvements can be made with an ECU remap, but gains are typically modest (5-10 kW). The engine responds well to maintenance, restoring it to optimal factory performance.
Fuel economy is excellent. Expect around 50-60 mpg (UK) (5.6 - 4.7 L/100km) in mixed driving for a Yaris. Real-world figures are very good due to the Atkinson cycle operation and VVT-iW system. It is one of Toyota's most economical petrol engines.
Yes. The Toyota 2NR-FKE is an interference engine. This means that if the timing chain were to fail or jump (though extremely rare), the pistons will collide with the open valves, causing severe internal engine damage. The chain is designed to last the life of the engine with proper oil maintenance.
Toyota mandates the use of API SN or SP grade, SAE 0W-20 viscosity engine oil. Using the correct low-viscosity oil is absolutely critical for the proper operation of the VVT-iW system and to achieve the engine's advertised fuel economy. Never use a thicker oil.
