The Mazda PEY6 is a 1,496 cc, naturally aspirated inline‑four petrol engine produced between 2014 and 2019. It features dual overhead camshafts (DOHC), 16 valves, and direct fuel injection (DISI), delivering a balance of efficiency and responsive performance for its vehicle class. Output is rated at 83 kW (113 PS) and 148 Nm of torque, providing adequate power for urban and highway driving.
Fitted primarily to the third-generation Mazda2 (DJ) and related Toyota models like the Yaris, the PEY6 was engineered for compact car applications prioritizing fuel economy, low emissions, and low running costs. Emissions compliance for its production period was met through advanced engine management and a three-way catalytic converter, aligning with Euro 5 standards for vehicles registered during this timeframe.
A documented service consideration involves potential for carbon buildup on intake valves, a known characteristic of direct injection engines. This is noted in Mazda service documentation for the DJ platform, often correlating with extended oil change intervals or predominantly short-trip driving. No major generational updates occurred within the PEY6's production run.

The high compression ratio and direct injection provide good fuel efficiency but require strict adherence to recommended oil change intervals to prevent carbon buildup on intake valves. Using the specified low-viscosity 0W-20 oil is critical for optimal fuel economy and engine protection. The timing chain is designed for the engine's lifespan under normal conditions. Regular maintenance and using high-quality fuel can mitigate common direct injection issues.
Oil Specs: Oil specification (viscosity and API/ACEA rating) is model and year-specific. Always consult the owner's manual or VIN-specific service data. 0W-20 is mandatory for optimal performance.
Emissions: Euro 5 certification applies to vehicles produced for the European market during 2014-2019 (VCA Type Approval applicable to specific VINs).
Power Ratings: Power and torque figures are specific to the exact engine variant and market homologation. Refer to official Mazda PT catalogue or vehicle documentation.

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.
Locate the full engine code stamped on the engine block, typically on a flat machined surface on the front face near the timing cover or on the exhaust side. The 8th digit of the VIN often corresponds to the engine type for that specific model year. Visually, the PEY6 is a transverse-mounted inline-four with a plastic intake manifold and direct injection fuel rail. Critical differentiation from similar engines involves checking the engine code prefix and specific component layouts detailed in the model-specific workshop manual.
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.
