The Ford P9PA is a 1,499 cc, inline‑three turbo‑petrol engine produced between 2018 and 2023. It features a DOHC 12‑valve layout, direct fuel injection, and a single twin‑scroll turbocharger. In standard tune it delivers 118–140 kW (160–190 PS) and peak torque of 240–270 Nm, enabling brisk urban and motorway performance.
Fitted to models such as the Fiesta ST, Puma ST, and Focus ST‑Line, the P9PA was engineered for responsive performance and everyday usability. Emissio…
Production years 2018–2020 meet Euro 6d-TEMP standards; 2021–2023 models comply with Euro 6d .
The Ford P9PA is a 1,499 cc inline‑three turbo‑petrol engineered for compact performance models (2018–2023). It combines direct injection with a twin‑scroll turbocharger to deliver responsive mid‑range torque and agile throttle response. Designed to meet Euro 6d-TEMP and Euro 6d emissions standards, it balances sporty character with regulatory compliance.

The Ford P9PA was used across Ford's B‑Car and C‑Car platforms with transverse mounting. This engine received platform-specific adaptations—reinforced mounts in the Fiesta ST and enhanced cooling in the Puma ST—and from 2021 the Focus ST-Line received updated engine calibration and GPF tuning, 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. 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 P9PA is generally robust when maintained properly. Early units (2018–2020) had HPFP sensitivity, but post-2021 revisions improved durability. Using 95+ RON fuel and correct 0W‑20 oil is essential. With proper care, 200,000 km longevity is achievable.
Top issues include high-pressure fuel pump wear, GPF clogging from short trips, cylinder deactivation solenoid faults, and turbo wastegate rattle. These are documented in Ford TSBs 22‑2145 and 21‑2089, and are manageable with correct maintenance.
The P9PA powers the Fiesta ST (Mk8), Puma ST, and Focus ST-Line/Active (1.5 EcoBoost variants) from 2018–2023. Output ranges from 160 PS (Focus) to 200 PS (Fiesta/Puma ST). All feature cylinder deactivation and a GPF.
Aftermarket ECU tuning is common on the P9PA 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 ~40 mpg UK combined. The Focus 1.5 EcoBoost achieves ~5.8 L/100km combined (~49 mpg UK). Real-world figures vary with driving style and GPF regeneration cycles.
Yes. The P9PA is an interference design. If the timing chain fails (rare but possible), valve-to-piston contact can cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine service under proper maintenance.
Ford specifies SAE 0W‑20 oil meeting WSS‑M2C945‑B. This low-viscosity oil supports cylinder deactivation and turbo cooling. Never use older Ford specs (e.g., 5W‑30) as they may impair deactivation and increase oil consumption.
