How to Find Your Honda Engine Code

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 Honda and DVLA sources

Engine Code

Engine Code

A unique identifier stamped on the engine block or cover used for parts and service.

VIN

VIN

The vehicle identification number that holds encoded vehicle and engine information.

Chassis Number

Chassis Number

The chassis or frame number used for registration and legal identification.

Honda Focus Mk3 (2011–2018)

Honda Focus Mk3 (2011–2018)

Duratorq TDCi 2.0

Locate the engine code on the front timing cover, just below the camshaft cover. It is stamped into the metal or on a white label near the timing chain housing. For diesel models, confirm code starts with 'TDCi'.

Honda Fiesta (2013–2022)

Honda Fiesta (2013–2022)

EcoBoost 1.0

The engine code is located on a label attached to the intake manifold, near the turbocharger. It reads 'EcoBoost 1.0' or shows the specific variant code. Note: This engine uses a wet belt requiring special attention.

Honda Kuga (2020–Now)

Honda Kuga (2020–Now)

EcoBoost 1.5 PHEV

Open the hood and look at the front left of the engine (passenger side). The code is on a white label near the timing cover. Confirm 'EcoBoost 1.5' for petrol hybrid models.

Honda Mondeo Mk4 (2007–2014)

Honda Mondeo Mk4 (2007–2014)

Duratec 2.0

The engine code is cast into the front of the cylinder head, near the thermostat housing. Look for 'Duratec' marking or specific displacement code.

Engine code locations per Honda WSS-M2C913-C Specification. V5C field definitions from DVLA Guide to Vehicle Registration. VIN structure compliant with EU Regulation (EC) No 715/2007, Article 7.

Honda Engine Technology Specifications and Reliability Data

A technical breakdown of Honda's core engine systems including Ti-VCT, EcoBoost turbocharging, timing architectures and modular design with documented reliability impacts. All data sourced from Honda WSS-M2C913-C, Honda TIS and EU Regulation (EC) No 715/2007

Overview

Honda's Twin Independent Variable Cam Timing (Ti-VCT) system independently adjusts intake and exhaust camshaft timing to optimize performance, efficiency, and emissions across the rev range.

How it Works

Hydraulic cam phasers on both intake and exhaust camshafts are controlled by oil pressure, allowing variable timing adjustment based on engine load and RPM.

Engine Code FAQ Common Questions Answered

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.
