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 mobility with spirited motorway capability. Emissions compliance was achieved through a gasoline particulate filter (GPF) and cooled exhaust gas recirculation (EGR), enabling full Euro 6d compliance across all production years.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) under sustained high-load conditions, highlighted in Ford Service Bulletin TSB 24‑1953. This issue stems from marginal lubrication in early Bosch HDP6 pump variants during thermal stress cycles. From early 2024, Ford implemented a revised HPFP with improved internal clearances and hardened components.
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 twin-scroll turbo provides immediate throttle response ideal for city driving but demands high-quality 95 RON (or 98 RON for tuned variants) to prevent knock under load. Ford WSS-M2C948-B1 (0W-20) oil is essential for GPF compatibility and timing chain longevity. Extended high-RPM operation may accelerate HPFP wear—early units (pre-early-2024) should be inspected per TSB 24-1953. The GPF requires periodic highway driving to enable passive regeneration; frequent short trips can trigger warning lights. Post-early-2024 engines include an upgraded HPFP with revised metallurgy.
Oil Specs: Requires Ford WSS-M2C948-B1 (0W-20) specification (Ford Owner’s Manual – Puma 2023). Not backward-compatible with older Ford oil specs.
Emissions: Euro 6d compliance confirmed for all 2022–2025 builds (VCA Type Approval #VCA/EMS/9682).
Power Ratings: Measured under ISO 1585 standards. 125 kW variant requires 98 RON fuel for optimal performance (Ford TIS Doc. F25100).

ISO 1585: Road vehicles — Engine test code
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.
Locate the engine code stamped on the front timing cover near the crank pulley (Ford TIS F24715). The 7th VIN digit for YYJA-equipped vehicles is typically 'Y'. Pre-early-2024 models use Bosch HDP6 HPFP with silver housing; post-early-2024 units feature black housing with revised internals. Critical differentiation from earlier 1.5L EcoBoost (YVDA): YYJA shares architecture but has updated ECU calibration and emissions tuning. Service parts for HPFP and injectors are production-date sensitive—verify via Ford EPC before ordering (TSB 24-1953).
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.
