The Toyota 2KD — FTV is a 2,494 cc, inline‑four turbo‑diesel engine produced between 2005 and 2023. It features a cast‑iron block, aluminium head, and a chain‑driven DOHC valvetrain with four valves per cylinder. This advanced design prioritises efficiency and torque, delivering outputs between 100–120 kW (136–163 PS) and torque figures of 343–400 Nm, making it ideal for SUVs and light commercial vehicles.
Fitted to models like the Hilux, Fortuner, and Innova, the 2KD —…

Production years 2005–2011 meet Euro 4 standards; 2012–2023 models meet Euro 5 compliance depending on market .
The Toyota 2KD-FTV is a 2,494 cc inline‑four turbo‑diesel engineered for SUVs and pickups (2005-2023). It combines common-rail injection with a variable nozzle turbocharger to deliver exceptional low-end torque and strong fuel economy. Designed to meet Euro 4 and Euro 5 standards, it balances rugged utility performance with modern emissions control.

The Toyota 2KD-FTV was used across Toyota's IMV platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced mounts in the Hilux and specific cooling packages for the Innova-and from 2015 the widespread adoption of DPF created minor ECU and exhaust revisions, creating no significant interchange limits. 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.
The 2KD-FTV's primary documented concern is potential injector seal failure in early builds, with elevated incidence in high-mileage or poorly maintained vehicles. Toyota TSB EG-0145-12 addresses this for affected units, while general reliability is otherwise very high. Extended oil change intervals and use of incorrect oil viscosity can exacerbate wear, making adherence to the maintenance schedule critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the 2KD-FTV is generally considered a very reliable and robust engine. Its main weakness is potential injector seal failure in early models (pre-2012), which Toyota addressed with a service bulletin. With regular oil changes using the correct specification and addressing EGR/DPF maintenance, it can easily exceed 300,000 km without major issues.
The most common issues are injector seal failure (early builds), EGR valve and cooler clogging, DPF blockage (especially with short trips), and turbocharger actuator failure. These are well-documented in Toyota service bulletins and are generally straightforward to diagnose and repair with the correct procedures.
The 2.5L 2KD-FTV was used extensively in Toyota's IMV platform vehicles: Hilux pickup (2005-2023), Fortuner SUV (2005-2023), Innova MPV (2005-2023), and Hiace van (2005-2019). It was a global workhorse engine, renowned for its torque and durability in tough conditions.
The 2KD-FTV has good tuning potential. ECU remaps can yield significant gains (20-40 kW and 50-100 Nm) by adjusting fuel maps and boost pressure. Its robust internals can handle these increases well. More advanced tuning involves larger turbos and intercoolers. Always ensure supporting modifications (clutch, cooling) are considered.
Fuel economy is very good for its size and output. In a Hilux or Fortuner, expect around 8.0-10.0 L/100km (28-35 mpg UK) combined in real-world driving. Highway cruising can be around 7.0 L/100km (40 mpg UK), while city driving may be 11.0-13.0 L/100km (24-28 mpg UK). Figures vary by model, year, load, and driving style.
Yes. The 2KD-FTV is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable with proper maintenance.
Toyota recommends 5W-30 viscosity oil meeting API CJ-4 or ACEA C2/C3 standards. Using 'Toyota Genuine Diesel Oil' or a high-quality fully synthetic oil is best. The oil should be changed every 10,000 km or 6 months to protect the high-pressure fuel system, turbo, and DPF.
