The Ford FYJA is a 1,498 cc, inline‑three turbocharged petrol engine produced between 2020 and 2023. It belongs to Ford's EcoBoost engine family and features direct fuel injection, dual overhead camshafts (DOHC), and an integrated exhaust manifold. In standard tune, it produces 88 kW (120 PS) and 170 Nm of torque, offering a balance of fuel efficiency and responsive performance for compact urban applications.
Fitted to models such as the Fiesta (Mk8) and Puma, the FYJA was engineered for economical city driving and light-duty commuting. Its character emphasizes low-end responsiveness and quiet operation. Emissions compliance is achieved via a gasoline particulate filter (GPF) and closed-loop lambda control, allowing it to meet Euro 6d-TEMP standards across its production run.
One documented concern is intake manifold runner flap sticking, particularly under frequent short-trip driving conditions. This issue, highlighted in Ford Service Action 20S04, arises from carbon buildup on the flap actuators. From 2021, revised actuator materials and updated ECU mapping were introduced to improve reliability.
All FYJA engines comply with Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/6789).
The Ford FYJA is a 1,498 cc inline‑three turbocharged petrol engine designed for compact models (2020–2023). It combines direct injection with an integrated exhaust manifold and variable valve timing to deliver responsive low-end torque and improved thermal efficiency. Designed to meet Euro 6d-TEMP emissions standards, it balances city drivability with fuel economy.

The integrated exhaust manifold and turbocharging provide strong low-RPM response ideal for city driving but require adherence to 15,000 km oil service intervals to prevent turbo bearing wear and carbon buildup. Ford WSS-M2C949-A (5W-30) oil is essential due to its thermal stability and protection of the high-pressure fuel pump. Short-trip driving increases GPF loading, necessitating periodic highway runs to trigger regeneration. The Bosch HDEV5 fuel pump is sensitive to fuel quality; use only E5 petrol meeting EN 228 standards. Intake runner flaps should be inspected per Ford SIB 20S04 if hesitation or rough idle is reported.
Oil Specs: Requires Ford WSS-M2C949-A (5W-30) specification (Ford SIB 20S04). Replaces prior WSS-M2C913-C and ACEA C2.
Emissions: All FYJA units comply with Euro 6d-TEMP standards (VCA Type Approval #VCA/EMS/6789). No full Euro 6d variant exists for this engine.
Power Ratings: Measured under SAE J1349 standards. Output maintained on regular unleaded (RON 95); premium fuel (RON 98) does not increase power.

The Ford FYJA was used across Ford's B3 platform with transverse mounting. This engine received platform-specific adaptations-shorter intake runners in the Puma and revised torque mounts in the Fiesta-and from 2021 the facelifted Fiesta ST-Line adopted the FYJA with enhanced cooling and updated ECU calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the starter motor (Ford TIP A32140). The 8th VIN digit indicates engine type ('Y' for 1.5L EcoBoost). Pre-2021 models have silver valve covers with black plastic cam covers; post-2021 units use gloss black valve covers. Critical differentiation from FYDA: FYJA produces 120 PS vs 140 PS; turbocharger actuator linkage differs. Service parts require build date verification - intake runner flaps before 06/2020 are incompatible with later units due to redesign per Ford SIB 20S04.
The FYJA's primary reliability risk is intake manifold runner flap sticking, with elevated incidence in urban short-trip driving. Internal Ford quality reports from 2021 indicated a significant share of pre-2021 units required flap service before 80,000 km, while UK DVSA MOT data shows increased emissions failures linked to GPF saturation in stop-start conditions. Frequent cold starts and low-speed operation increase carbon buildup, making regular highway driving and timely servicing critical.
