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.
The engine code is essential for ordering parts, diagnosing issues, and verifying compatibility. It is not the same as the VIN or chassis number. This guide shows exactly where to find it - by model and engine type - using official Mitsubishi and DVLA sources
A unique identifier stamped on the engine block or cover used for parts and service.
The vehicle identification number that holds encoded vehicle and engine information.
The chassis or frame number used for registration and legal identification.
Locate the engine code on the valve cover at the top of the engine. It is stamped or on a label reading '4B11' or '4B11T' for turbo variants.
The engine code is located on a label attached to the front timing cover, near the camshaft housing. Look for '4J12' marking.
Open the hood and look at the front of the engine block near the timing cover. The code '4N14' is stamped into the metal or on a white label.
The engine code is cast into the cylinder head, visible from the side of the engine. Look for '4G63' or '4G63T' for turbo models.
Engine code locations per Mitsubishi Motors Service Manual. V5C field definitions from DVLA Guide to Vehicle Registration. VIN structure compliant with EU Regulation (EC) No 715/2007, Article 7.
A technical breakdown of Mitsubishi's core engine systems including MIVEC, GDI turbocharging, timing architectures and modular design with documented reliability impacts. All data sourced from Mitsubishi Motors Service Manual and EU Regulation (EC) No 715/2007
Mitsubishi's MIVEC (Mitsubishi Innovative Valve timing Electronic Control) system varies valve timing and lift to optimize performance, efficiency, and emissions across the rev range.
Uses hydraulic pressure and electronic control to switch between two cam profiles - low-lift for efficiency at low RPM, high-lift for power at high RPM.
4G92 (1992)
High-RPM power mode
4G63 (1995)
Dual cam profile switching
4B11 (2007)
Continuous variable timing
4J12 (2012)
Integrated with Atkinson cycle
Oil pressure sensitivity
Requires regular oil changes
VTC actuator wear
Rattling noise on cold start
Cam phaser failure
Reduced performance, check engine light

Authoritative data on Mitsubishi's global engine production, plant operations, and strategic partnerships. All figures sourced from Mitsubishi Motors Annual Reports, Sustainability Reports, and EU industrial compliance records.
Mitsubishi manufactures engines at primary facilities in Japan and Thailand.
Mitsubishi produces approximately 160,000–180,000 engines per year. Note the steady decline in Diesel production as Mitsubishi phases out diesel for PHEV focus.
Note: Diesel production has declined as Mitsubishi focuses on PHEV technology. Outlander PHEV remains best-selling PHEV SUV in Europe.
Mitsubishi is part of the Renault-Nissan-Mitsubishi Alliance, sharing technology and platforms. Historical engine licensing agreements with Hyundai and Proton.
Licensed to Hyundai for Sonata and Santa Fe (1990s–2000s)
Used by Proton in Malaysian market vehicles
Mitsubishi Motors Strategic Partnerships
Shift in production reflects Mitsubishi's PHEV focus and diesel phase-out.
This aligns with Commission Regulation (EU) 2017/1151 (WLTP/RDE) and EU 2035 ICE phase-out roadmap.

The most common questions about engine codes, what they mean, how to find them and how this database works
Confirm the full engine designation using vehicle-specific manufacturer records and the engine marking. An engine serial number, a registration record and a marketed power badge are not automatically the same identifier. Match the VIN/build data and the installed engine before selecting parts or a replacement.
No. A factory-application reference and a replacement-interchange decision are different. Match the full engine designation, vehicle build data, emissions equipment, controls and relevant supplier/OEM information.
No. Records have different review states. Read the correction notice, source scope and application limits on the individual record. Missing technical fields must not be inferred from similar engine codes.
