The Ford UEJB is a 1,596 cc, inline‑four turbocharged direct — injection petrol engine produced between 2012 and 2018. It features dual overhead camshafts (DOHC), four valves per cylinder, and a twin — scroll turbocharger with variable valve timing. In standard form it delivered 118 kW (160 PS) at 6,000 rpm with 240 Nm of torque at 1,750–4,500 rpm, offering strong low — end response and refined performance.
Fitted to models such as the Ford Focus MkIII, C — MAX, and Mondeo MkIV…
Production years 2012–2014 meet Euro 5 standards; 2015–2018 models comply with Euro 6 .
The Ford UEJB is a 1,596 cc inline‑four turbocharged direct-injection petrol engine engineered for compact and mid-size hatchbacks/sedans (2012–2018). It combines a twin-scroll turbocharger with variable valve timing and high-pressure direct injection to deliver responsive torque and smooth power delivery. Designed to meet Euro 5 and Euro 6 emissions standards, it balances performance with regulatory compliance and urban drivability.

The Ford UEJB was used across Ford's C1 and CD4 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Mondeo for NVH reduction and updated turbo routing in the Focus ST-Line—and from 2015 the introduction of gasoline particulate filters (GPF) created interchange limits between Euro 5 and Euro 6 variants. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The UEJB is generally robust with proper maintenance. Its main weakness is the high-pressure fuel pump in early builds. Using 95 RON minimum fuel, adhering to oil change intervals, and avoiding excessive short trips greatly improve longevity. Euro 6 variants require occasional highway driving to maintain GPF health.
Top issues include high-pressure fuel pump wear, turbo wastegate rattle, minor carbon buildup on intake valves, and GPF clogging in Euro 6 models. These are documented in Ford service bulletins FE-15/09 and workshop manuals from 2012–2018.
It powered the Ford Focus MkIII (2012–2018), C-MAX (2012–2015), Mondeo MkIV (2014–2018), and S-MAX (2015–2018) with 160 PS output. All are front-wheel-drive transverse applications with EcoBoost branding.
Aftermarket ECU tuning is common on the UEJB 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.
Typical consumption is 7.0–7.8 L/100km (36–30 mpg UK) in mixed driving. Highway cruising can achieve 5.8 L/100km (~49 mpg UK). Economy suffers with aggressive driving, low-quality fuel, or frequent short trips that prevent GPF regeneration.
Yes. The UEJB is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing severe internal damage. However, the chain is robust and designed for the engine's lifetime with proper oil maintenance.
Ford specifies SAE 5W-30 oil meeting WSS-M2C948-B1 (low-SAPS, ACEA C2/C3). This protects the turbo, timing chain, and emissions systems. Extended drain intervals are not recommended—change every 15,000 km or annually.
