The Ford TXDB is a 999 cc, inline‑three turbocharged petrol engine produced between 2018 and 2023. It features direct fuel injection, a single twin — scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 92 kW (125 PS) and 170 Nm of torque, with strong low — rpm responsiveness for urban drivability.
Fitted to models such as the Fiesta ST — Line, Puma, and EcoSport, the TXDB was engineered for compact efficiency without sacrificing mid — range t…
Production years 2018–2023 meet Euro 6d-TEMP standards .
The Ford TXDB is a 999 cc inline‑three turbocharged petrol engineered for subcompact and compact models (2018–2023). It combines direct injection with a twin-scroll turbocharger to deliver responsive low-end torque and agile urban performance. Designed to meet Euro 6d-TEMP emissions, it balances efficiency with sporty drivability.

The Ford TXDB was used across Ford's B2E/B6 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations-shortened exhaust manifolds in the Puma and reinforced mounts in the EcoSport-and from 2021 the Fiesta facelift adopted updated HPFP hardware, creating minor service part distinctions. 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 TXDB is generally robust when maintained properly. Early units (2018–2020) had HPFP sensitivity to fuel quality, but post-2021 revisions improved durability. Regular oil changes with Ford-specified 0W-20 and occasional highway driving for GPF regeneration are key to longevity.
The main issues are high-pressure fuel pump wear, GPF regeneration faults from short-trip driving, turbo actuator sticking, and minor cam cover oil leaks. These are documented in Ford service bulletins, particularly SIB 19M02 for HPFP concerns.
The TXDB powers the 1.0L EcoBoost 125 variants of the Fiesta (Mk8, 2018–2023), Puma (2019–2023), and EcoSport (2020–2023). All meet Euro 6d-TEMP emissions standards and feature GPF and twin-scroll turbo technology.
Aftermarket ECU tuning is common on the TXDB 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.
Excellent for its class. In a Fiesta 1.0 EcoBoost 125, expect ~5.8 L/100km (city) and ~4.3 L/100km (highway), or about 52 mpg UK combined. Real-world mixed driving typically returns 48–55 mpg (UK) with conservative use.
Yes. The TXDB is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. Fortunately, the chain is robust and designed for life-of-engine use under proper maintenance.
Ford specifies SAE 0W-20 oil meeting WSS-M2C945-B1 standard. This low-viscosity oil ensures proper GPF compatibility and turbo lubrication. Never substitute with non-approved oils, as they may harm emissions systems or reduce HPFP life.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website.
