The Toyota 2AD-FTV is a 2,231 cc, inline‑four turbo‑diesel engine produced between 2005 and 2015. It features a double overhead camshaft (DOHC) and 16 valves, paired with common rail direct injection and a variable nozzle turbocharger (VNT). Output varied by application, with power ranging from 100 kW (136 PS) to 120 kW (163 PS) and torque from 310 Nm to 340 Nm.
Fitted to models like the Avensis, RAV4, and Verso, the 2AD-FTV was engineered for refined, efficient performance in family vehicles. It prioritized smooth operation, low emissions, and strong mid-range torque for relaxed highway cruising and towing. Emissions compliance was managed through its exhaust gas recirculation (EGR) system and diesel particulate filter (DPF), meeting Euro 4 standards.
One documented concern is carbon buildup in the intake manifold and EGR system, which can lead to reduced performance and increased emissions. This characteristic, noted in Toyota service documentation for the AD-series engines, is often attributed to the design of the EGR cooler and intake ports. Toyota issued technical service bulletins recommending specific cleaning procedures to restore performance.

Production years 2005–2015 meet Euro 4 standards for applicable markets (Toyota Emissions Certification Docs).
The Toyota 2AD-FTV is a 2,231 cc inline‑four turbo‑diesel engineered for mid‑size sedans, SUVs, and MPVs (2005-2015). It combines DOHC 16-valve architecture with common rail direct injection and a variable nozzle turbocharger to deliver strong, linear torque and quiet operation. Designed to meet Euro 4 emissions standards, it balances performance with environmental compliance.

The VNT turbo provides strong, linear torque ideal for highway cruising but requires strict adherence to 15,000 km oil change intervals to prevent turbo and EGR system issues. ACEA B4 (5W-30) oil is critical due to its specific formulation for turbo diesel engines with EGR. Extended idling should be minimized to reduce carbon buildup in the intake manifold. The Denso common-rail system demands ultra-low-sulfur diesel (ULSD) to prevent injector clogging. EGR and DPF systems require periodic cleaning or regeneration to maintain emissions compliance and prevent limp-mode events, per Toyota SIB ENG-005.
Oil Specs: Requires API CF-4/CH-4 or ACEA B4 specification oil (Toyota Owner's Manual 2008). Modern equivalents (API CK-4) are acceptable if viscosity is correct.
Emissions: Euro 4 certification applies to all production years (Toyota Emissions Docs). No Euro 5 variants were produced for this engine code.
Power Ratings: Measured under JIS D 1001 standards. Output figures are for gross power; net power is slightly lower (Toyota PT-2010).

The Toyota 2AD-FTV was used across Toyota's ZZE15x/ACA3x platforms with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds and exhaust configurations-and no significant facelift revisions during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the block's machined surface near the cylinder head, typically on the exhaust side (Toyota RM987E). The 8th VIN digit often corresponds to the engine code for European market vehicles ('D' for diesel variants). The 2AD-FTV is visually identified by its DOHC cam covers, common-rail injectors, and variable nozzle turbocharger. Critical differentiation from 2AD-FHV: The 2AD-FTV has a single-stage turbo; the 2AD-FHV has a twin-turbo setup. Engine blocks and many internal components are shared, but turbo and intake systems are not interchangeable.
The 2AD-FTV's primary reliability risk is EGR and intake system carbon buildup, with elevated incidence in short-trip urban use. Toyota service records indicate this was a frequent cause for performance-related complaints. Stop-start driving and infrequent highway use make regular intake cleaning critical.
