The Ford M1JM is a 1,498 cc, inline-three turbocharged petrol engine produced between 2018 and 2023. It forms part of Ford's EcoBoost engine family, featuring direct fuel injection, twin-independent variable cam timing (Ti-VCT), and a compact turbocharger. Designed for responsive urban driving, it delivers 103 kW (140 PS) and 240 Nm of torque, with peak torque available from 1,600 rpm for strong low-end pull.
Fitted to models such as the Focus ST-Line, Fiesta ST, and Puma, the M1JM engine was engineered to balance spirited performance with improved fuel efficiency in compact Ford vehicles. Emissions compliance is achieved through a three-way catalytic converter and cooled exhaust gas recirculation (EGR), allowing Euro 6.2 compliance across its production run for all major European markets.
One documented concern is intercooler pipe disconnection under high thermal cycling, highlighted in Ford Service Action 19S12. This issue stems from material fatigue at the plastic-to-rubber joint in the charge air system. From 2020, revised intercooler piping with reinforced coupling design was implemented across all M1JM builds to improve long-term durability.
Production years 2018–2023 meet Euro 6.2 standards (VCA UK Type Approval #VCA/EMS/5678).
The Ford M1JM is a 1,498 cc inline-three turbocharged petrol engine engineered for compact performance applications (2018–2023). It combines direct fuel injection with twin-independent variable cam timing (Ti-VCT) to deliver responsive low-end torque and agile throttle response. Designed to meet Euro 6.2 standards, it balances sporty driving dynamics with modern emissions requirements.

The compact turbo provides strong low-RPM torque ideal for city driving but requires adherence to 15,000 km oil change intervals to prevent timing chain and turbo bearing wear. Ford WSS-M2C949-A (5W-30) oil is essential due to its thermal stability and protection for the balance-shaft-integrated chain system. Extended idling and short trips increase carbon buildup on intake valves. The high-pressure fuel pump demands minimum 95 RON fuel to prevent knock and injector coking. Post-2020 models feature upgraded intercooler piping; pre-2020 units should be inspected per Ford SIB 19S12. EGR and catalytic converter longevity depend on regular highway runs to prevent soot accumulation.
Oil Specs: Requires Ford WSS-M2C949-A (5W-30) specification (Ford SIB 19S12). Replaces ACEA C2/C3 in Ford applications.
Emissions: Euro 6.2 certification applies to all M1JM models (2018–2023) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ECE R85 standards. Full output requires 95 RON or higher fuel (Ford TIS Doc. E2020-M1JM).

The Ford M1JM was used across Ford's C2 and B3 platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Fiesta and revised cooling layouts in the Puma-and from 2020 the facelifted Focus adopted the M1JM with enhanced engine mounts, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-left side of the cylinder block near the exhaust manifold (Ford TIS E2020-M1JM). The 8th VIN digit indicates engine type ('J' for M1JM series). Pre-2020 models have black plastic intercooler piping with grey clamps; post-2020 units use reinforced black piping with integrated metal sleeves. Critical differentiation from 1.0L EcoBoost: M1JM has three exhaust ports and a larger turbo housing. Service parts require model-year verification—intercooler pipes before 08/2019 are incompatible with later revisions per Ford SIB 19S12.
The M1JM's primary reliability risk is intercooler piping failure on early builds, with elevated incidence in stop-start urban use. Internal Ford quality reports from 2019 noted a significant number of pre-2020 engines requiring pipe replacement before 100,000 km, while UK DVSA records show increased catalytic converter faults in short-trip driven vehicles. Frequent thermal cycling and low-speed operation increase pipe and EGR stress, making regular inspection and highway driving critical.
