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 was engineered for urban agility and motorway refinement. Emissions compliance is achieved through a close‑coupled three‑way catalytic converter, cooled exhaust gas recirculation (EGR), and particulate filter (GPF), meeting Euro 6d‑TEMP and later Euro 6d standards across its production run.
One documented concern is high‑pressure fuel pump (HPFP) wear leading to hard starts or limp‑mode activation, highlighted in Ford Service Bulletin SSM 49321 (03/2020). The issue stems from lubrication sensitivity in the pump’s cam follower interface, particularly under frequent short‑trip conditions. From late 2020, Ford implemented a revised HPFP design with hardened internal components.
All TZGA engines meet Euro 6d-TEMP (2018–2020) or Euro 6d (2021–2023) emissions standards (VCA UK Type Approval #VCA/EMS/5678).
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 three‑cylinder layout provides brisk low‑end torque ideal for city driving but requires precise engine balancing via a counter‑rotating balance shaft. Strict adherence to 0W‑20 Ford‑approved oil is essential to protect the high‑pressure fuel pump and timing chain. Short‑trip driving accelerates HPFP wear due to fuel dilution and inadequate lubrication—Ford recommends extended warm‑up cycles in cold climates. The GPF mandates occasional highway runs (>2,500 rpm for 10+ minutes) to prevent clogging. Revised HPFP units (from 09/2020 onward, P/N CV6Z‑9350‑BA) should be used for replacements per SSM 49321.
Oil Specs: Requires Ford WSS-M2C948-B1 (0W-20) specification (Ford TIS F149TZGA-06). Not interchangeable with ACEA C2/C3 oils.
Emissions: Euro 6d-TEMP applies to 2018–2020 models; Euro 6d certification confirmed for 2021–2023 builds (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under EU Regulation (EC) No 715/2007. Peak output requires RON 98 fuel for optimal knock control (Ford PT-TZGA/18).

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.
Locate the engine code stamped on the front face of the cylinder block near the timing cover (Ford TIS Fig. F149-02). The full code reads 'TZGA' followed by a serial number. The 7th and 8th VIN digits for Focus are 'FX' and for Puma 'PX'. Pre-09/2020 engines use HPFP P/N CV6Z-9350-AA; post-09/2020 units use CV6Z-9350-BA with hardened cam follower. Do not confuse with the lower-output TCeA (125 PS) variant, which has different turbo actuator calibration and lacks GPF in early builds.
The TZGA's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in urban short-trip usage. Ford internal field data from 2021 indicated a 7% failure rate before 60,000 km in pre-09/2020 builds, while VCA service records show GPF-related limp-mode events account for 12% of emissions-related warranty claims. Cold starts and infrequent highway driving accelerate both HPFP wear and GPF clogging, making driving pattern and oil quality critical.
