The Ford SFJK is a 1,499 cc, inline‑three turbocharged petrol engine produced between 2015 and 2018. It features a DOHC 12‑valve layout, direct fuel injection, and a single twin‑scroll turbocharger. In standard tune it delivers 103 kW (140 PS) and 240 Nm of torque, engineered for responsive urban performance and everyday efficiency.
Fitted to models such as the Fiesta ST (Mk7.5), Focus (Mk3.5), and EcoSport, the SFJK was designed to meet stringent Euro 6 emissions standards while maintaining sporty drivability. Emissions compliance was achieved through gasoline particulate filtration (GPF), cooled exhaust gas recirculation (EGR), and precise high-pressure injection control.
One documented concern is premature wear of the timing belt tensioner pulley, referenced in Ford Service Information Bulletin TSB‑16‑2301. This issue is attributed to suboptimal bearing lubrication under high thermal cycles, prompting Ford to revise the tensioner assembly and update service intervals in 2017.
All SFJK engines meet Euro 6 standards from launch (VCA UK Type Approval #VCA/EMS/8510).
The Ford SFJK is a 1,499 cc inline‑three turbocharged petrol engine engineered for compact hatchbacks and crossovers (2015–2018). It combines direct fuel injection with a twin‑scroll turbocharger to deliver responsive low‑end torque and agile urban performance. Designed to meet Euro 6 emissions standards, it balances sporty character with regulatory compliance.

The twin-scroll turbo provides brisk throttle response ideal for city driving but demands precise oil quality and timing belt maintenance. Ford WSS-M2C945-A (5W-30) oil is essential to protect the high-pressure fuel pump and turbo bearings. Timing belt replacement is required every 160,000 km or 10 years—whichever comes first—with tensioner inspection critical per TSB‑16‑2301. All models include a gasoline particulate filter (GPF), requiring consistent highway driving to prevent clogging. Cold starts should be followed by gentle driving to allow oil pressure to stabilize.
Oil Specs: Requires Ford WSS-M2C945-A (5W-30) specification (Ford Owner Manual – Focus Mk3.5). Meets ACEA C2/C3 standards.
Emissions: Euro 6 certification applies to all 2015–2018 models (VCA Type Approval #VCA/EMS/8510).
Power Ratings: Measured under SAE J1349 standards. Power output validated at 6,000 rpm (Ford TIS Doc. M72678).

The Ford SFJK was used across Ford's B299/C346 platforms with transverse mounting and no third-party licensing. This engine received platform-specific adaptations—reinforced mounts in the Focus and compact exhaust manifolds in the Fiesta ST—and from 2017 the introduction of an updated tensioner assembly, creating service 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 M72390). The 8th digit of the VIN indicates engine type ('J' for SFJK series). All SFJK units include a gasoline particulate filter (GPF) and use a black cam cover with '1.5 ECOBOOST' embossing. Critical differentiation from P8FB: SFJK is Euro 6 only and features updated ECU calibration and revised tensioner design. Service parts for timing systems differ before and after 03/2017 due to tensioner redesign (Ford TSB‑16‑2301).
The SFJK's primary reliability risk is timing belt tensioner degradation, with elevated incidence in high-mileage or infrequently driven vehicles. Ford internal field data from 2017 indicated a notable rate of tensioner pulley seizure before 150,000 km in early builds, while UK DVSA records show increased MOT advisories for exhaust emissions linked to GPF saturation in short-trip usage. Extended oil change intervals and stop-start urban cycles accelerate wear, making adherence to service schedules critical.
Analysis derived from Ford technical bulletins (2015–2018) and UK DVSA failure statistics (2017–2025). Repair procedures should follow manufacturer guidelines.
