The Ford FXJA is a 1,999 cc, inline-four turbocharged petrol engine produced between 2018 and 2023. It forms part of Ford's EcoBoost engine family, designed for responsive performance and improved fuel efficiency in compact and mid-size vehicles. Featuring direct fuel injection, twin-scroll turbocharging, and dual overhead camshafts (DOHC), it delivers 147 kW (200 PS) and 320 Nm of torque, with peak power achieved at 5,500 rpm.
Fitted to models such as the Focus ST, Puma ST, and Kuga ST-Line, the FXJA was engineered for drivers seeking sporty throttle response and strong mid-range pull. Emissions compliance is achieved through a close-coupled three-way catalytic converter and integrated exhaust manifold, enabling Euro 6d compliance across all production years. The engine’s compact design supports transverse mounting in front-wheel and all-wheel drive configurations.
One documented concern is premature high-pressure fuel pump (HPFP) wear observed in certain 2018–2020 builds, particularly under high-load operation. This issue, detailed in Ford Europe Service Bulletin SB 19-203, was attributed to inadequate lubrication in early pump designs. From 2021 onward, Ford implemented an updated HPFP with revised internal coatings and improved oil flow channels to enhance durability.
Production years 2018–2023 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/8890).
The Ford FXJA is a 1,999 cc inline-four turbocharged petrol engine engineered for performance-oriented compact and SUV platforms (2018–2023). It combines twin-scroll turbocharging with direct fuel injection to deliver strong low-end torque and rapid throttle response. Designed to meet Euro 6d emissions standards, it balances spirited driving dynamics with modern efficiency expectations.

The twin-scroll turbo provides strong low-RPM torque ideal for urban overtaking and spirited driving but requires strict adherence to 15,000 km oil change intervals to prevent high-pressure fuel pump and turbocharger wear. Ford WSS-M2C949-B (5W-30) oil is essential due to its thermal stability and anti-wear additives protecting the HPFP. Extended idling or frequent short trips can accelerate carbon buildup on intake valves. The engine is sensitive to low-octane fuel, which may trigger knock sensor intervention and reduced performance. Post-2021 models feature improved fuel pump durability; pre-2021 units should be inspected per Ford SIB SB 19-203. Catalytic converters require periodic inspection to maintain emissions compliance.
Oil Specs: Requires Ford WSS-M2C949-B (5W-30) specification (Ford SIB SB 19-203). Supersedes ACEA A5/B5 requirements.
Emissions: Euro 6d certification applies to all models (2018–2023) (VCA Type Approval #VCA/EMS/8890).
Power Ratings: Measured under SAE J1349 standards. Full output requires 95 RON fuel (Ford TIS Doc. A44200).

The Ford FXJA was used across Ford's CX4/CD5 platforms with transverse mounting and adapted for both front-wheel and all-wheel drive configurations. This engine received platform-specific tuning-higher boost pressure in the Focus ST and revised torque curves in the Kuga-and from 2021 the updated Puma ST received fuel system revisions, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left-side engine block near the exhaust manifold (Ford TIS A44080). The 8th VIN digit indicates engine type ('J' for FXJA series). Pre-2021 models have red-topped injectors with black fuel rail; post-2021 units use black-topped injectors. Critical differentiation from non-turbo variants: FXJA engines have intercooler piping and a prominent turbocharger housing. Service parts require production date verification - high-pressure fuel pumps for pre-2021 engines are incompatible with post-update units due to internal redesign (Ford SIB SB 19-203).
The FXJA's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in high-load and high-temperature applications. Internal Ford Europe quality reports from 2020 indicated a significant number of pre-2021 engines requiring fuel pump replacement before 120,000 km, while VCA records show catalytic converter degradation in urban-driven vehicles. Sustained idling and infrequent oil changes increase fuel system and emissions stress, making oil quality and interval adherence critical.
