The Mazda P5Z7 is a 1,498 cc, inline‑four petrol engine produced between 2003 and 2007. It features a dual overhead camshaft (DOHC) valvetrain and sequential multi‑point fuel injection, delivering a balance of efficiency and responsive performance for its vehicle class. Output is rated at approximately 74 kW (100 PS) and 130 Nm of torque, providing adequate power for urban and highway driving.
Fitted primarily to the second-generation Mazda2 (DY) and related Ford models like the Fiesta, the P5Z7 was engineered for compact car applications prioritizing fuel economy and low running costs. Emissions compliance for its production period was met through standard three-way catalytic converter technology, aligning with Euro 3 standards for vehicles registered during this timeframe.
A documented service consideration involves the ignition coil packs, which can develop internal faults leading to misfires. This is noted in Mazda service documentation for the DY platform, often correlating with high mileage or exposure to excessive under-bonnet heat. No major generational updates occurred within the P5Z7's production run before its replacement by newer engine families.

The naturally aspirated design offers predictable, linear power delivery suitable for daily commuting. Regular oil and filter changes using the specified grade are crucial for longevity, particularly for maintaining the timing chain. Fuel system components like injectors may require cleaning over time to maintain optimal performance and economy. Ignition coil packs are a known wear item; symptoms like misfires or rough running should prompt inspection. Always refer to the specific vehicle's service schedule and manual for maintenance intervals and fluid specifications.
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.
Emissions: Euro 3 certification applies to vehicles produced for the European market during 2003-2007 (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 P5Z7 was used across Mazda's compact platforms with transverse mounting. This engine received platform-specific adaptations and was succeeded by the Z-series. All adaptations are documented in OEM technical bulletins.
Locate the full engine code stamped on the engine block, typically on a flat machined surface near the gearbox flange or on the front timing cover. The 8th digit of the VIN often corresponds to the engine type for that specific model year. Visually, the P5Z7 is a transverse-mounted inline-four with a plastic intake manifold and coil-on-plug ignition. Critical differentiation from similar engines involves checking the engine code prefix and specific component layouts detailed in the model-specific workshop manual. Service parts are generally interchangeable within the P5Z7 code for the same model year.
The P5Z7's primary reliability focus is on age-related wear of ignition components and potential for carbon buildup. While generally robust, lack of maintenance can lead to common failures. Adherence to service schedules is critical for long-term reliability.
