The Ford YYJA is a 1,498 cc, inline‑three turbo‑petrol engine produced from 2022 to 2025. It features direct fuel injection, a single twin — scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 110–125 kW (150–170 PS) with torque between 240–270 Nm, offering responsive low‑end performance ideal for compact SUVs and hatchbacks.
Fitted to models such as the Puma, Fiesta, and Focus, the YYJA was engineered for fuel — efficient urban mobilit…
All YYJA production years (2022–2025) comply with Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9682).
The Ford YYJA is a 1,498 cc inline‑three turbo‑petrol engineered for compact hatchbacks and crossovers (2022–2025). It combines direct injection with a twin‑scroll turbocharger to deliver brisk low‑end torque and refined throttle response. Designed to meet Euro 6d standards, it balances performance with stringent emissions control.

The Ford YYJA was used across Ford's B‑Car and C‑Car platforms with transverse mounting and exclusive to European and Australasian markets. This engine received platform-specific calibrations—revised cooling in the Puma and optimized NVH tuning in the Fiesta—and from early 2024 the Focus received the updated HPFP variant, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
The YYJA's primary reliability risk is high-pressure fuel pump (HPFP) degradation in early builds, with elevated incidence in track or towing use. Ford internal field data (2024) indicated a measurable uptick in HPFP replacements before 60,000 km in pre-early-2024 units, while UK DVSA records show GPF-related warnings are common in vehicles driven exclusively in urban cycles. Sustained high-load operation and low-quality fuel make OEM-specified oil and fuel critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The YYJA is generally robust when maintained properly, but early models (2022–early 2024) have known HPFP weaknesses. Post-early-2024 revisions significantly improved fuel system durability. Using correct 0W-20 oil and 95+ RON fuel, plus avoiding constant short trips, greatly enhances longevity.
Top issues include HPFP failure (pre-early-2024), GPF clogging from urban driving, turbo wastegate rattle, and coolant leaks from the thermostat housing. These are documented in Ford TSBs and owner service records, not anecdotal reports.
The YYJA powers the Fiesta (150 PS), Puma (155 PS), and Focus (150 PS) from 2022–2025. It is exclusive to three-cylinder EcoBoost variants in Europe and Australia, and is not used in North American models.
Yes. Stage 1 ECU remaps typically yield +20–30 kW safely due to strong stock internals. However, early HPFP units may not support aggressive tuning—upgraded fuel systems are recommended for Stage 2+. Always use 98 RON fuel with tuned setups.
In a Puma 1.5L EcoBoost, expect ~7.0 L/100km (city) and ~5.0 L/100km (highway), or about 42 mpg UK combined. Real-world mixed driving typically yields 39–46 mpg (UK), depending on driving style and GPF regeneration cycles.
Yes. The YYJA is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and generally durable with proper oil maintenance.
Ford specifies 0W-20 synthetic oil meeting WSS-M2C948-B1. This low-SAPS formulation protects the GPF and ensures proper chain lubrication. Never use older Ford oil specs or non-approved 5W-30 oils.
