FORD UEJE engine (2020–2025) – Specs, Problems & Compatibility Database

The Ford UEJE is a 1,999 cc, inline‑four turbocharged petrol engine produced between 2020 and 2025. It features a DOHC 16‑valve layout, direct fuel injection, and a twin‑scroll turbocharger, delivering 172 kW (237 PS) and 370 Nm of torque. This performance-oriented variant of the EcoBoost family uses an integrated exhaust manifold and variable valve timing for responsive power delivery and thermal efficiency.

Fitted primarily to the Ford Focus ST Mk4 (C519) and Puma ST (JX), the UEJE was engineered for sporty dynamics and track-capable durability. Emissions compliance is achieved through a gasoline particulate filter (GPF), cooled exhaust gas recirculation (EGR), and a close‑coupled three‑way catalytic converter, meeting Euro 6d standards across its entire production run.

One documented concern is premature wear of the high-pressure fuel pump (HPFP) cam follower, leading to fuel pressure instability and misfire codes. This issue is referenced in Ford Service Bulletin SSM 51284 (11/2021), which attributes the failure to insufficient lubrication under sustained high-RPM operation. From mid-2022, Ford introduced a revised HPFP with a hardened cam follower and improved oil feed channel.

All UEJE engines meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/7892).

UEJE Technical Specifications

The Ford UEJE is a 1,999 cc inline‑four turbocharged petrol engine engineered for performance hatchbacks and crossovers (2020–2025). It combines direct injection with a twin‑scroll turbocharger and variable valve timing to deliver high specific output and responsive throttle behavior. Designed to meet Euro 6d standards, it integrates emissions controls without compromising sporty driving dynamics.

Practical Implications

The twin-scroll turbo provides sharp throttle response ideal for spirited driving but demands strict adherence to 0W‑20 Ford‑approved oil to protect the HPFP cam follower and timing chain. Sustained high-RPM use (e.g., track days) accelerates HPFP wear if oil is degraded or incorrect. The GPF requires occasional highway runs (>2,500 rpm for 15+ minutes) to prevent clogging. Revised HPFP units (from 06/2022 onward, P/N CV7Z‑9350‑CB) should be used for replacements per SSM 51284. Pre-2022 engines benefit from proactive HPFP inspection at 60,000 km.

Data Verification Notes

Oil Specs: Requires Ford WSS-M2C948-B1 (0W-20) specification (Ford TIS F200UEJE-06). Not interchangeable with ACEA C2/C3 oils.

Emissions: Euro 6d certification confirmed for all model years (VCA Type Approval #VCA/EMS/7892).

Power Ratings: Peak output requires RON 98 fuel for optimal knock control and turbo response (Ford PT-UEJE/20).

UEJE Compatible Models

The Ford UEJE was used exclusively in Ford's performance variants with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts and upgraded cooling in the Focus ST and stiffer subframe bushings in the Puma ST—with identical ECU calibration across both. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped on the front timing cover near the oil pump (Ford TIS Fig. F200-02). The full code reads 'UEJE' followed by a serial number. The 7th and 8th VIN digits for Focus ST are 'FX'. All UEJE engines use a red valve cover and twin-scroll turbo with integrated exhaust manifold. Do not confuse with the lower-output L3TC (200 PS) variant used in Edge ST, which has a different turbo housing and no GPF.

HPFP Revision

Evidence:

Ford SSM 51284

Pre-06/2022:

Original HPFP (P/N CV7Z-9350-AA) susceptible to cam follower wear under high-RPM stress.

Post-06/2022:

Revised HPFP (P/N CV7Z-9350-CB) with hardened cam follower and enhanced oil gallery per Ford SSM 51284.
GPF Maintenance

Evidence:

Ford TIS Doc. F200UEJE-05

Regeneration:

Active regeneration triggered automatically; passive regeneration requires sustained load (>2,500 rpm for ≥15 min).

Warning Signs:

Reduced boost, power loss above 4,000 rpm, or P2002 DTC indicate GPF saturation.

Common Reliability Issues - FORD UEJE

The UEJE's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear, with elevated incidence in track or aggressive driving conditions. Ford internal durability testing from 2022 noted a 9% failure rate before 70,000 km in pre-06/2022 builds under high-RPM duty cycles, while VCA service records show GPF-related derate events account for 14% of emissions-related warranty claims. Extended high-load operation without oil monitoring accelerates HPFP degradation, making oil quality and driving pattern critical.

High-pressure fuel pump (HPFP) cam follower wear
Symptoms: Misfires under load, P0087/P0191 fuel rail pressure faults, rough idle after hot restart.
Cause: Insufficient lubrication at cam follower interface during sustained high-RPM operation, exacerbated by oil degradation or incorrect viscosity.
Fix: Replace with latest OEM HPFP (P/N CV7Z-9350-CB) and update PCM calibration per Ford SSM 51284.
Gasoline particulate filter (GPF) saturation
Symptoms: Power reduction above 4,000 rpm, increased backpressure, P2002 efficiency below threshold.
Cause: Inadequate passive regeneration due to predominantly urban driving or short trips; oil ash accumulation over time.
Fix: Perform forced regeneration via Ford IDS; if ash-loaded, replace GPF assembly with OEM unit.
Turbocharger oil feed line coking
Symptoms: Blue smoke on deceleration, turbo bearing whine, reduced boost pressure.
Cause: Thermal soak after aggressive driving carbonizes oil in feed line, restricting lubrication to turbo bearings.
Fix: Replace oil feed and return lines with OEM high-temp versions; allow 30-second cool-down idle after hard use.
Timing chain tensioner oil starvation
Symptoms: Intermittent P0016/P0017 cam correlation codes, rattle on cold start.
Cause: Sludge buildup in oil passages restricts flow to hydraulic tensioner, often from extended oil intervals or incorrect oil.
Fix: Flush oil system, replace tensioner and guides with OEM kit, and adhere strictly to 15,000 km oil change intervals.
