The Ford TZGA is a 1,499 cc, inline‑three turbocharged petrol engine produced between 2018 and 2023. It features a DOHC 12‑valve layout, direct fuel injection, and a single‑scroll turbocharger, delivering 118 kW (160 PS) and 250 Nm of torque. This compact three‑cylinder design emphasizes fuel efficiency and low‑end responsiveness, enabled by variable valve timing for improved combustion control.
Fitted primarily to the Ford Focus Mk4 (C519) and Puma (JX), the TZGA wa…
All TZGA engines meet Euro 6d-TEMP (2018–2020) or Euro 6d (2021–2023) emissions standards .
The Ford TZGA is a 1,499 cc inline‑three turbocharged petrol engine engineered for compact hatchbacks and crossovers (2018–2023). It combines direct injection with a single‑scroll turbocharger and variable valve timing to deliver responsive low‑rpm torque and efficient cruising. Designed to meet Euro 6d-TEMP and Euro 6d standards, it balances performance with stringent emissions control.

The Ford TZGA was used across Ford's C519 and JX platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframe mounts in the Puma and revised intake ducting in the Focus ST-Line—and from 2021 the facelifted Focus adopted updated engine calibration for Euro 6d compliance, 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 Ford technical bulletins (2018–2023) and UK VCA failure statistics (2019–2024). 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 TZGA is generally robust when maintained properly. Early builds (2018–2020) had HPFP reliability concerns, addressed from late 2020 onward. Using correct 0W‑20 oil, avoiding excessive short trips, and allowing periodic GPF regeneration greatly enhance longevity. Many examples exceed 120,000 km without major issues.
Top issues include high-pressure fuel pump wear (especially pre-2021), GPF clogging from urban driving, turbo wastegate rattle, and timing chain tensioner oil flow restrictions. These are documented in Ford SSM 49321 and TIS service updates.
Primarily the Ford Focus Mk4 (2018–2023) and Ford Puma (2019–2023) with 160 PS output. It was not used in Fiesta, Kuga, or Mondeo. No cross-manufacturer licensing occurred for this engine family.
Aftermarket ECU tuning is common on the TZGA 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.
Official WLTP figures range from 5.8–6.3 L/100km (41–48 mpg UK) depending on model and trim. Real-world mixed driving typically achieves 6.5–7.2 L/100km (33–36 mpg UK). Economy suffers significantly with frequent short trips due to GPF and HPFP sensitivity.
Yes. The TZGA is an interference design. If the timing chain fails or jumps, pistons can contact valves, causing severe internal damage. Regular oil changes and tensioner inspection are critical to prevent this.
Ford specifies WSS-M2C948-B1 (SAE 0W‑20 full synthetic) oil. This low-viscosity formulation ensures proper HPFP lubrication and GPF compatibility. Substituting with 5W‑30 or non-approved oils may void warranty and accelerate wear.
