The Ford SNJB is a 1,499 cc, inline‑three turbocharged petrol engine introduced in 2018 as part of the updated EcoBoost family. It features a DOHC 12‑valve layout, direct fuel injection, and a single twin‑scroll turbocharger. In standard tune it produces 92 kW (125 PS) and 200 Nm of torque, optimized for urban efficiency and responsive low‑end drivability.
Fitted primarily to the Fiesta (Mk8), Puma, and Transit Courier, the SNJB was engineered to meet stringent Euro 6d em…
All SNJB engines meet Euro 6d standards from launch (VCA UK Type Approval #VCA/EMS/9530).
The Ford SNJB is a 1,499 cc inline‑three turbocharged petrol engine engineered for compact hatchbacks and light commercial vehicles (2018–present). It combines direct fuel injection with a twin‑scroll turbocharger to deliver brisk low‑end torque and urban agility. Designed to meet Euro 6d emissions standards from launch, it balances efficiency with regulatory compliance.

The Ford SNJB was used across Ford's B299/C519 platforms with transverse mounting and no third-party licensing. This engine received platform-specific calibrations—revised ECU maps in the Fiesta for stop-start integration and compact intercooler routing in the Transit Courier—and from 2021 the introduction of an updated HPFP cam follower design, creating service distinctions. All adaptations are documented in OEM technical bulletins.
The SNJB's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear, with elevated incidence in vehicles driven primarily on short urban trips or with extended oil change intervals. Ford internal field data from 2021 indicated a notable rate of HPFP-related failures before 90,000 km in early builds, while UK DVSA records show increased MOT advisories for lambda sensor drift linked to GPF saturation. Stop-start urban cycles and infrequent highway driving accelerate wear, making adherence to service schedules critical.
Analysis derived from Ford technical bulletins (2018–2023) and UK DVSA failure statistics (2020–2025). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The SNJB offers good fuel economy and urban drivability with Euro 6d compliance. Early units (2018–2020) had HPFP cam follower concerns, but post-2021 revisions improved durability. With proper maintenance—especially using correct 0W-20 oil and timely service—well-cared-for examples can exceed 200,000 km reliably.
Key issues include HPFP cam follower wear, GPF clogging in city-driven cars, timing belt tensioner noise, and coolant leaks from the thermostat housing. These are documented in Ford service bulletins TSB‑20‑2155 and TSB‑21‑1105.
The SNJB appears in the Fiesta Mk8 (2018–present), Puma (2019–present), and Transit Courier (2020–present) as the 1.5L EcoBoost 125 PS variant. It was not licensed to other manufacturers.
Yes, but modestly. Stage 1 ECU remaps typically yield +10–15 kW safely. Enthusiasts often upgrade the intercooler and exhaust. However, aggressive tuning without supporting mods may accelerate HPFP or turbo wear, especially on pre-2021 builds.
In a Fiesta 1.5 EcoBoost 125 PS, expect ~6.5 L/100km (city) and ~4.6 L/100km (highway), or ~54 mpg UK combined. Puma and Transit Courier variants average 50–55 mpg UK in mixed driving, depending on load and driving style.
Yes. The SNJB is an interference engine. If the timing belt fails, pistons can contact valves, causing catastrophic damage. This underscores the importance of adhering to the 160,000 km/10-year replacement interval.
Ford specifies SAE 0W‑20 oil meeting WSS‑M2C945‑B1 (or newer) standard. This low-viscosity, low-SAPS oil protects the turbo, HPFP, and emissions systems. Using incorrect oil can lead to cam follower and HPFP failure.
