The Mazda PEY6 is a 1,496 cc inline‑four petrol engine engineered for compact hatchbacks (2014-2019). It combines DOHC architecture with direct fuel injection to deliver responsive, economical performance. Designed to meet Euro 5 emissions standards, it balances everyday drivability with low running costs.

The Mazda PEY6 was used across Mazda's compact platforms with transverse mounting. This engine received platform-specific adaptations and was succeeded by newer Skyactiv-G variants. 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 PEY6's primary reliability focus is on managing carbon buildup inherent to direct injection systems. While generally robust, lack of maintenance can lead to common failures. Adherence to service schedules and using correct oil is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
Generally, yes. The PEY6 is a modern and efficient design. Its main long-term concern is carbon buildup on intake valves, a common trait of direct injection engines. This can be managed with periodic cleaning and proper maintenance. Using the correct 0W-20 oil and adhering to service intervals is crucial for longevity.
The most frequent issues are carbon buildup on intake valves causing running problems, failing VVT actuators leading to noise and performance loss, high-pressure fuel pump failures, and oil leaks from the oil filter housing gasket. These are typical wear-and-tear or design-characteristic items for this engine type.
The PEY6 engine was primarily used in the third-generation Mazda2 (DJ chassis, 2014-2019). It was also the basis for the 1.5L engine used in the fourth-generation Toyota Yaris (XP130) during the same period, where it was part of Toyota's NZ engine family.
Significant power gains are limited due to the naturally aspirated, high-compression design focused on efficiency. Basic modifications like a cold air intake might offer minor improvements. ECU remapping potential is very limited and can negatively impact fuel economy and emissions compliance.
Fuel economy is excellent for its era. Expect combined figures around 5.0-5.8 L/100km (56-49 mpg UK), depending on the specific vehicle, transmission (manual/automatic), and driving conditions. Its high compression ratio and direct injection contribute to this efficiency.
Yes, the Mazda PEY6 is an interference engine. If the timing chain were to fail or jump timing, the pistons can collide with the open valves, causing severe internal engine damage. However, the timing chain is designed to last the engine's lifespan under normal operating conditions.
The PEY6 engine requires SAE 0W-20 engine oil with an API SN (or higher) specification. This low-viscosity oil is mandatory for achieving the engine's designed fuel economy and performance. Using a different viscosity can affect engine protection and efficiency. Always consult your owner's manual.
