The Ford YYJD is a 1,499 cc, inline‑three turbo‑petrol engine produced between 2020 and 2024. It features direct fuel injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 118 kW (160 PS) and 250 Nm of torque, with strong low‑rpm responsiveness ideal for compact SUVs and hatchbacks.
Fitted to models such as the Mk8 Fiesta ST‑Line, Puma ST, and Kuga mild‑hybrid variants, the YYJD was engineered for performance‑oriented efficiency with Euro 6d compliance. Emissions control was achieved through gasoline particulate filtration (GPF), cooled exhaust gas recirculation (EGR), and precise lambda management, enabling full conformity with stringent EU emissions standards.
One documented concern is high-pressure fuel pump (HPFP) drive lobe wear on the intake camshaft, highlighted in Ford Technical Service Bulletin TSB‑23‑0517. This issue arises from thermal fatigue during repeated high‑load driving without adequate cooldown periods. From late 2022, Ford introduced revised camshaft metallurgy and updated HPFP internals to reduce failure incidence.
All production years (2020–2024) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/9452).
The Ford YYJD is a 1,499 cc inline‑three turbo‑petrol engineered for compact performance vehicles (2020–2024). It combines direct injection with a twin‑scroll turbocharger to deliver brisk low‑end response and smooth power delivery. Designed to meet Euro 6d standards, it balances sporty drivability with stringent emissions control.

The twin‑scroll turbo provides immediate throttle response ideal for spirited driving but demands high‑quality fuel (98 RON recommended) to prevent knock and HPFP/camshaft stress. Oil changes every 15,000 km using Ford WSS‑M2C949‑A (5W‑30) are critical to maintain turbo bearing and chain longevity. Extended high‑load driving (e.g., track use, mountain roads) without cooldown periods may accelerate HPFP drive lobe wear—per TSB 23‑0517, affected camshafts should be replaced with updated units. The GPF requires occasional highway driving (>2,000 rpm for 15+ minutes) to enable passive regeneration and avoid clogging.
Oil Specs: Requires Ford WSS‑M2C949‑A (5W‑30) specification (Ford Owner’s Manual). Equivalent to ACEA C2/C5.
Emissions: Euro 6d applies to all model years (2020–2024) (VCA Type Approval #VCA/EMS/9452).
Power Ratings: Measured under ISO 1585 standards. Output assumes 98 RON fuel (Ford TIS Doc. YYJD‑A201).

ISO 1585: Road vehicles — Engine test code
The Ford YYJD was used across Ford's B‑ and C‑segment performance platforms with transverse mounting and exclusive to European and global emerging markets. This engine received platform-specific calibrations—enhanced cooling in the Puma ST and mild-hybrid integration in the Kuga—creating minor ECU and hardware interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filter housing (Ford TIS YYJD‑A103). The 7th VIN digit indicates engine family ('J' for YYJD series). All YYJD units feature a black plastic intake manifold with “1.5 ECOBOOST” embossed and a visible GPF bulge in the exhaust manifold. Critical differentiation from non-GPF variants: YYJD always includes a gasoline particulate filter. ECU part number must match calibration—Puma ST uses ECU 2S6J‑12A650‑AF, while Kuga Hybrid uses 2S6J‑12A650‑AG. Swapping without reprogramming causes limp mode (Ford TSB 23‑1124).
The YYJD's primary reliability risk is HPFP drive lobe wear on the intake camshaft in early builds, with elevated incidence in sustained high-load or track-day use. Ford internal field data from 2023 indicated a measurable uptick in camshaft replacements before 65,000 km in ST models, while UK DVSA records show minimal emissions-related failures due to robust GPF management. Aggressive driving without cooldown periods increases thermal and mechanical stress, making fuel quality and driving habits critical.
Analysis derived from Ford technical bulletins (2023–2024) and UK DVSA failure statistics (2020–2025). Repair procedures should follow manufacturer guidelines.
