The Ford PHFC is a 1,499 cc, inline‑three turbo‑petrol engine introduced in 2018 as part of Ford’s EcoBoost family. It features a DOHC 12‑valve layout, direct fuel injection, and a single twin‑scroll turbocharger. In standard form it produces 118–140 kW (160–190 PS) with torque between 240–270 Nm, offering brisk response and strong low‑rpm pull.
Fitted to models such as the Fiesta ST, Puma ST, and Focus ST‑Line, the PHFC was engineered for sporty yet efficient urban and mo…
Production years 2018–2019 meet Euro 6d-TEMP standards; 2020–present models comply with Euro 6d .
The Ford PHFC is a 1,499 cc inline‑three turbo‑petrol engineered for compact performance models (2018–present). It combines direct injection with a twin‑scroll turbocharger to deliver responsive low‑end torque and agile mid‑range pull. Designed to meet Euro 6d-TEMP (early builds) and Euro 6d (2020 onward), it balances sporty character with regulatory compliance.

The Ford PHFC was used across Ford's B‑Car and C‑Car platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations-reinforced mounts in the Fiesta ST and enhanced cooling in the Puma ST-and from 2020 the Focus ST-Line adopted updated engine calibration for Euro 6d, creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The PHFC is generally robust when maintained properly. Early models (2018–2021) had HPFP concerns, but Ford’s mid-2021 update resolved most issues. Using 95+ RON fuel, adhering to oil specs (0W-20 WSS-M2C949-A), and allowing post-drive cooldown greatly enhance longevity.
Top issues include high-pressure fuel pump wear (pre-2021), GPF clogging from short trips, turbo actuator calibration drift, and minor valve cover oil seepage. These are documented in Ford TSBs and are manageable with proper maintenance.
The PHFC powers the Fiesta ST (Mk8, 2018–present), Puma ST (2019–present), and Focus ST-Line 1.5L (2020–present). All are transverse-mounted applications in Ford’s global B- and C-platform vehicles, compliant with Euro 6d emissions.
Aftermarket ECU tuning is common on the PHFC platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Fiesta ST, expect ~7.5 L/100km (city) and ~5.2 L/100km (highway), or ~45 mpg UK combined. Real-world mixed driving typically returns 40–50 mpg (UK), depending on driving style and GPF regeneration cycles.
Yes. The PHFC is an interference engine. Timing chain failure—though rare due to front-mounted design—could cause piston-to-valve contact. Ford specifies the chain as lifetime, but severe oil neglect may compromise it.
Ford mandates 0W-20 synthetic oil meeting WSS-M2C949-A specification. This low-viscosity oil ensures GPF compatibility and proper chain lubrication. Do not substitute with older 5W-30 or non-approved oils.
