The Ford YTT is a 1,499 cc, inline‑three turbo‑petrol engine produced between 2015 and 2020. It features direct fuel injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 103 kW (140 PS) and 240 Nm of torque, with responsive low‑end performance suited for compact hatchbacks and crossovers.
Fitted to models such as the Mk7.5 Fiesta, EcoSport, and B‑Max, the YTT was engineered as a cost‑effective, fuel‑efficient a…
All production years (2015–2020) meet Euro 6b standards (VCA UK Type Approval #VCA/EMS/4321).
The Ford YTT is a 1,499 cc inline‑three turbo‑petrol engineered for compact hatchbacks and crossovers (2015–2020). It combines direct injection with a twin‑scroll turbocharger to deliver brisk low‑end response and smooth power delivery. Designed to meet Euro 6b standards, it balances performance with emissions control.

The Ford YTT was used across Ford's B‑segment platforms with transverse mounting and exclusive to European and global emerging markets. This engine received platform-specific calibrations—revised cooling in the EcoSport and detuned variants in base Fiesta trims—creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
The YTT's primary reliability risk is high-pressure fuel pump (HPFP) drive wear in early builds, with elevated incidence in urban short-trip use. Ford internal field data from 2018 indicated a measurable uptick in HPFP replacements before 70,000 km in city-driven vehicles, while UK DVSA records show minimal emissions-related failures due to the absence of a GPF. Repeated cold starts and low-quality fuel increase mechanical stress, making fuel quality and driving patterns critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The YTT is generally robust when maintained properly. Early models (2015–2018) had HPFP concerns under frequent short-trip use, but late-2018+ revisions improved durability. Using 95 RON fuel, adhering to oil change intervals, and occasional highway driving greatly enhance longevity. The timing chain is low-wear and typically lasts the engine’s life.
The top issues are high-pressure fuel pump wear (early models), turbo wastegate rattle, coolant leaks from the thermostat housing, and ignition coil failures. These are documented in Ford TSBs 17‑2156 and 19‑0412. Most are preventable with proper fuel quality and maintenance habits.
The YTT powers the Mk7.5 Fiesta (1.5 EcoBoost 140 PS), EcoSport (2016–2020), and B-Max (2015–2017) across European and global markets. It’s not used in North America. All variants lack a gasoline particulate filter (GPF), distinguishing them from later XYJC engines.
Yes. Stage 1 ECU remaps typically yield +15–20 kW safely on stock hardware. However, aggressive tuning without HPFP upgrades may accelerate wear—especially on pre-2018 engines. Always use 98 RON fuel if tuned, and note that emissions legality depends on local regulations (no GPF simplifies compliance in some regions).
In a Fiesta 1.5 EcoBoost 140 PS, expect ~6.5 L/100km (city) and ~4.7 L/100km (highway), or ~49 mpg UK combined. Real-world economy is excellent for urban use due to strong low-end torque and absence of GPF regeneration cycles.
Yes. The YTT is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine service—no scheduled replacement is required if oil is changed regularly.
Ford specifies SAE 5W‑30 oil meeting WSS‑M2C949‑A (or newer). This low-SAPS oil protects turbo bearings and ensures proper chain lubrication. Change every 15,000 km or annually. Using non-approved oil can void warranty and accelerate component wear.
