The Ford TZJA is a 1,499 cc, inline‑three turbocharged 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 tune it produces 118 kW (160 PS) at 6,000 rpm and 240 Nm of torque from 1,600–4,000 rpm, delivering responsive performance with improved fuel efficiency over larger naturally aspirated units.
Fitted to models including the Ford Focus Mk4, Pu…

All TZJA engines meet Euro 6d-TEMP (2018–2020) or Euro 6d (2021–present) standards (VCA UK Type Approval #VCA/EMS/FORD/TZJA).
The Ford TZJA is a 1,499 cc inline‑three turbocharged petrol engine engineered for compact and subcompact vehicles (2018–present). It combines direct injection with a twin-scroll turbocharger to deliver strong mid-range torque and refined operation. Designed to meet Euro 6d emissions standards, it balances performance with regulatory compliance and real-world efficiency.

The Ford TZJA was used across Ford's C2 and B2E platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Puma for NVH control and unique exhaust manifolds in the Focus—and from 2021 all variants adopted updated calibration for Euro 6d compliance, creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
The TZJA's primary reliability risk is low-speed pre-ignition (LSPI) under aggressive driving conditions, with elevated incidence in early 2018–2020 builds. Ford Engineering Bulletin FEB‑19‑08 documented knock-related piston damage in <1% of high-mileage fleet units, while UK DVSA data shows GPF regeneration faults as a secondary concern in urban-driven vehicles. Short-trip cycles and incorrect oil use increase LSPI and soot accumulation, making oil specification and driving pattern 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 TZJA is generally reliable when maintained correctly. Early units (2018–2020) had LSPI concerns addressed via software updates. Using the correct 0W‑20 oil and avoiding short trips significantly improves longevity. The timing belt system is robust if replaced at the 160,000 km interval.
Main issues include low-speed pre-ignition (LSPI), GPF clogging from short trips, timing belt tensioner wear, and turbo wastegate rattle. These are documented in Ford bulletins FEB‑19‑08 and SIB 05‑19‑12. Most are preventable with proper maintenance.
The TZJA powers the Ford Focus Mk4 (2018+), Puma (2019+), and Transit Courier (2021+), all with 1.5L EcoBoost branding. Output ranges from 155–160 PS depending on model and hybrid configuration.
Yes—ECU remapping typically yields +20–30 PS safely on stock hardware. However, aggressive tuning increases LSPI risk. Supporting mods like intercooler upgrades and higher-octane fuel (RON 98) are recommended. Hybrid Puma variants require additional inverter calibration.
In a Focus 1.5 EcoBoost 160 PS, expect 6.2–6.8 L/100km (42–38 mpg UK) combined. The Puma mild-hybrid achieves 5.8–6.3 L/100km (49–45 mpg UK). Real-world figures vary with driving style, but GPF-equipped engines perform best on longer journeys.
Yes. The TZJA is an interference engine. If the timing belt fails, pistons will contact open valves, causing severe internal damage. Adherence to the 160,000 km belt replacement interval is critical.
Ford specifies WSS-M2C948-B1 (SAE 0W‑20 full synthetic) oil. This low-SAPS formulation protects the GPF and reduces LSPI risk. Substituting with non-approved oils may void warranty and increase engine wear.
