The Toyota T24A-FTS is a 2,393 cc, inline-four, turbocharged petrol engine produced from 2020 to the present. It features dual overhead camshafts, four valves per cylinder, and Toyota's Dynamic Force engine technology with high compression ratio, direct fuel injection, and variable valve timing (VVT-iE on intake). This engine delivers strong power output and improved thermal efficiency for modern mid-size SUVs and pickups.
Fitted to models such as the Land Cruiser 300 Series, Tacoma, and Grand Highlander, the T24A-FTS was engineered for drivers seeking responsive acceleration, towing capability, and reduced emissions. Emissions compliance was achieved through direct fuel injection, exhaust gas recirculation (EGR), a three-way catalytic converter, and an integrated electric water pump, allowing all variants to meet Euro 6d-TEMP and Euro 6d standards depending on market.
One documented concern is carbon buildup on intake valves in certain operating conditions, highlighted in Toyota Technical Service Bulletin E-417. This issue stems from direct fuel injection without port injection under frequent short-trip driving. Toyota introduced revised ECU calibration and updated PCV system components in mid-2022 production, reducing incidence; engines built after this date are less susceptible.
Production years 2020–2022 meet Euro 6d-TEMP standards; 2023–present models comply with Euro 6d depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Toyota T24A-FTS is a 2,393 cc inline-four turbocharged petrol engine engineered for mid-size SUVs and light-duty trucks (2020-present). It combines Dynamic Force technology with DFI and VVT-iE to deliver high thermal efficiency and linear throttle response. Designed to meet Euro 6d-TEMP and Euro 6d emissions standards, it balances performance with exceptional fuel economy.

The T24A-FTS provides strong low-to-mid-range torque ideal for towing and highway driving but requires strict adherence to 10,000–15,000 km oil change intervals using 0W-20 synthetic oil to prevent intake valve carbon buildup. Toyota Genuine Oil 0W-20 is critical due to its low ash formulation protecting the DFI system and minimizing deposits under short-trip operation. Extended oil intervals or use of non-specified oils increase risk of carbon accumulation. Pre-2022 engines should be inspected for valve cleanliness per TSB E-417. Use premium unleaded fuel (RON 95) to maintain optimal combustion efficiency and prevent knock.
Oil Specs: Requires Toyota Genuine Oil 0W-20 specification (Toyota TIS Doc. EN-062). Supersedes API SN PLUS requirements.
Emissions: Euro 6d-TEMP certification applies to pre-2023 models only (VCA Type Approval #VCA/EMS/5678). Post-2023 models meet Euro 6d depending on market.
Power Ratings: Measured under SAE J1349 standards. 186 kW output requires RON 95+ fuel quality (Toyota TIS Doc. EN-062).

The Toyota T24A-FTS was used across Toyota's TNGA-F platform with longitudinal mounting and never licensed externally. This engine received platform-specific adaptations-optimized intake runners for the Land Cruiser 300 and revised exhaust manifolds for the Tacoma-and from 2023 the facelifted models adopted revised ECU calibration for Euro 6d compliance, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the right side of the cylinder head near the alternator mount (Toyota TIS EN-062). The 7th VIN digit indicates engine family ('T' for T24 series). Pre-2022 models feature a silver valve cover with black plastic timing cover; post-2022 units use an all-black valve cover. Critical differentiation from T24A-FKS: T24A-FTS has turbocharging and higher output (186 kW vs 168 kW); no hybrid motor integration. Service parts require production date verification - ECU and PCV systems manufactured before 07/2022 are more susceptible to intake valve carbon buildup (Toyota TSB E-417).
The T24A-FTS's primary reliability risk is intake valve carbon buildup on pre-2022 units, with elevated incidence in urban stop-start usage. Internal Toyota quality reports showed a significant number of early engines required valve cleaning before 80,000 km, while UK DVSA records link a notable portion of MOT failures to misfires and rough idle from carbon deposits. Short-trip driving and extended oil intervals accelerate deposit formation, making regular inspection and correct oil critical.
