The Mazda FPY3 is a 1,998 cc, inline‑four naturally aspirated petrol engine produced between 2014 and 2018. It features a dual overhead camshaft (DOHC) 16‑valve cylinder head and direct fuel injection (DISI), delivering an output of 118 kW (160 PS) and 210 Nm of torque. Its high compression ratio enables efficient combustion for its class.

Production years 2014–2015 meet Euro 5 standards; 2016–2018 models meet Euro 6 standards depending on market .
The Mazda FPY3 is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and SUVs (2014-2018). It combines direct fuel injection with a DOHC 16-valve architecture to deliver smooth, linear power delivery. Designed to meet Euro 5 and Euro 6 emissions standards, it balances performance with fuel efficiency.

The Mazda FPY3 was used across Mazda's BM/BN and KE platforms with transverse mounting. This engine received platform-specific ECU calibrations for the Mazda 3 versus the CX‑5, creating interchange limits for control units. 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 FPY3's primary reliability consideration is intake valve carbon buildup, a common trait of direct-injection engines. Mazda TSB TSB-15-003 documents this phenomenon, noting it can lead to drivability complaints if neglected. Extended oil change intervals or frequent short trips can accelerate carbon accumulation, making adherence to the maintenance schedule and occasional professional cleaning critical.
Analysis derived from Mazda technical bulletins (2014-2018) and owner-reported data. 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 FPY3 is generally considered a very reliable engine. Its main consideration is managing intake valve carbon buildup, which is common to all direct-injection engines. With regular oil changes using the correct 0W-20 oil and periodic intake cleaning, the FPY3 can easily exceed 200,000 km without major issues.
The most frequent issues are carbon buildup on the intake valves, occasional VVT actuator noise on cold start, and potential failure of the high-pressure fuel pump. PCV valve clogging is also a simple but common maintenance item. These are well-documented in Mazda service information.
This engine was primarily used in the third-generation Mazda 3 (BM/BN chassis, 2014-2018) and the first-generation CX-5 (KE chassis, 2015-2017) in certain markets. It was the standard 2.0L Skyactiv-G petrol engine for these models during those years.
Yes, but gains are modest due to its naturally aspirated design and high compression ratio. Common modifications include an ECU remap, performance air filter, and cat-back exhaust, which can yield 5-10 kW extra. Significant power increases require forced induction, which is complex and costly.
Fuel economy is very good for a naturally aspirated engine. Expect around 6.0–6.5 L/100km (47–43 mpg UK) in combined driving for a Mazda 3. The heavier CX-5 will consume slightly more, around 6.5–7.0 L/100km (43–40 mpg UK). Actual figures depend heavily on driving style.
Yes. The Mazda FPY3 is an interference engine. This means that if the timing chain were to fail (which is extremely rare), the pistons would collide with the open valves, causing severe internal engine damage. Fortunately, the timing chain is very robust.
Mazda specifies SAE 0W-20 synthetic oil with an API SN (or higher) rating. Using this exact viscosity is crucial for optimal fuel economy, protecting the VVT system, and ensuring proper lubrication under all operating conditions. Do not substitute with a thicker oil.
