The Ford JQMA is a 1,998 cc, inline — four naturally aspirated petrol engine produced between 2020 and 2023. It forms part of Ford's Dynamic Force engine family, featuring dual injection (direct and port), dual VCT, and an Atkinson cycle for improved thermal efficiency. In standard tune, it delivers 125 kW (170 PS) and 200 Nm of torque, prioritising fuel economy and smooth operation in mid — size applications.
Fitted to models including the Mondeo Hybrid and S — MAX, the JQMA e…
All production years (2020–2023) meet Euro 6d emissions standards (UK VCA Type Approval #VCA/FORD/9124).
The Ford JQMA is a 1,998 cc inline-four naturally aspirated petrol engine designed for hybrid applications (2020–2023). It combines dual injection with Atkinson cycle operation to deliver high thermal efficiency and low emissions. Engineered for seamless integration with electric drive systems, it balances drivability with regulatory compliance in medium-duty use cases.

The Ford JQMA was used across Ford's CD535 platform with transverse mounting and hybrid powertrain integration. This engine received platform-specific adaptations-longer intake runners in the Mondeo Hybrid and revised exhaust manifolds in the S-MAX-and from 2022 the facelifted Mondeo adopted the JQMA variant with enhanced EGR cooling and sensor shielding, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The JQMA's primary reliability risk is crankshaft position sensor failure, with elevated incidence in vehicles subjected to frequent thermal cycling. Internal Ford quality reports from 2022 indicated a significant number of pre-2022 units required sensor replacement before 80,000 km, while UK DVSA data shows increased stalling-related MOT advisories in urban hybrids. Short-trip driving and delayed oil changes increase sensor and timing chain stress, making maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The JQMA engine is generally reliable when maintained properly, though pre-2022 models have a known crankshaft position sensor issue. Later revisions (2022+) with updated hardware show improved durability. Regular oil changes using Ford WSS-M2C949-B (0W-20) and avoiding prolonged short-trip driving significantly enhance long-term reliability, especially in hybrid applications.
The most common issues are crankshaft position sensor failure due to thermal stress, timing chain tensioner wear, high-pressure fuel pump degradation, and EGR valve coking. These are documented in Ford SIB 21A03 and addressed through updated parts and service procedures. Using correct oil and driving style greatly reduces risk.
The JQMA 2.0L petrol engine is used exclusively in the Mondeo Hybrid (2020–2023) and S-MAX (2020–2023) hybrid variants. It is not available in non-hybrid configurations. All variants meet Euro 6d emissions standards and are paired with a 105 kW electric motor for combined output.
Tuning options are limited due to hybrid integration and Atkinson cycle design. Minor ECU remaps can optimise throttle response and regenerative braking logic, but significant power gains are not feasible without compromising hybrid efficiency or triggering safety protocols. Aftermarket support is minimal due to system complexity.
In combined hybrid driving, the JQMA achieves approximately 5.1 L/100km (55.1 mpg UK) in the Mondeo Hybrid and 5.3 L/100km (53.3 mpg UK) in the S-MAX. Real-world consumption varies: city driving may drop to 4.8 L/100km using electric assist, while highway runs average 5.6 L/100km. Battery state and driving style significantly influence results.
Yes, the Ford JQMA is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can occur, resulting in severe internal damage. Maintaining proper oil levels and following service intervals is essential to prevent tensioner failure and ensure chain longevity.
Ford specifies WSS-M2C949-B (0W-20) synthetic oil for the JQMA engine. This low-viscosity formulation reduces friction and supports fuel economy targets in hybrid applications. Oil changes should be performed every 20,000 km or annually, whichever comes first, to maintain reliability.
