The Toyota 2NZ-FE is a 1,497 cc, inline‑four petrol engine produced between 2000 and 2016. It features dual overhead camshafts (DOHC) and 16 valves with VVT-i, designed for compact, fuel-efficient vehicles like the Yaris and Echo. Output was modest, typically around 77 kW (105 PS) and 140 Nm of torque, prioritizing smooth operation and low-cost ownership.
Fitted primarily to the Yaris (XP10, XP90) and Echo (NCP50), the 2NZ-FE was engineered for reliable, urban transportation. It prioritized refinement, low emissions, and ease of maintenance. Emissions compliance was managed through its electronic fuel injection and VVT-i system, meeting Euro 3 and Euro 4 standards depending on model year.
One documented characteristic is susceptibility to oil sludge buildup under severe service conditions, which can lead to reduced oil flow and bearing wear. This issue, highlighted in Toyota Service Bulletin T-SB-0094-10, is often linked to extended oil change intervals or use of non-specified oil. Toyota recommends strict adherence to maintenance schedules to prevent this condition.

Production years 2000–2005 meet Euro 3 standards; 2006–2016 models meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/4567).
The Toyota 2NZ-FE is a 1,497 cc inline‑four petrol engine engineered for subcompact hatchbacks and sedans (2000-2016). It combines DOHC 16-valve architecture with VVT-i to deliver smooth, economical power and low emissions. Designed to meet Euro 3 and Euro 4 standards, it balances everyday drivability with fuel efficiency.

The DOHC VVT-i design provides smooth, linear power delivery ideal for city driving but requires strict adherence to 15,000 km oil change intervals to prevent sludge buildup. Using the correct ILSAC GF-3/GF-4 specification oil (5W-30) is critical for maintaining VVT-i solenoid function and preventing internal deposits. Extended idling or frequent short trips should be minimized to reduce moisture accumulation in the oil. The timing chain is designed for life-of-engine service but should be inspected if unusual noise is detected. Fuel injectors may require cleaning if fuel quality is poor.
Oil Specs: Requires API SL/SM or ILSAC GF-3/GF-4 specification oil (Toyota Owner's Manual 2005). Modern equivalents (API SN/SP, ILSAC GF-5/GF-6) are acceptable.
Emissions: Euro 3 certification applies to 2000-2005 models; Euro 4 applies to 2006-2016 models (VCA Type Approval #VCA/EMS/4567).
Power Ratings: Measured under JIS D 1001 standards. Output figures are for net power (Toyota PT-2005).

The Toyota 2NZ-FE was used across Toyota's XP1x/NCP5x platforms with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds and engine mounts-and no significant facelift revisions affecting core components 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 RM789E). The 8th VIN digit often corresponds to the engine code for European market vehicles ('N' for NZ-series). The 2NZ-FE is visually identified by its DOHC cam covers and electronic fuel injection (no carburetor). Critical differentiation from 1NZ-FE: The 2NZ-FE has a 1,497cc displacement; the 1NZ-FE is 1,496cc. Engine blocks are nearly identical, but pistons and some internal components differ slightly.
The 2NZ-FE's primary reliability risk is oil sludge buildup under severe service conditions, with elevated incidence in high-mileage or poorly maintained examples. Toyota service records indicate this was a documented concern, particularly for vehicles subjected to frequent short trips. Infrequent oil changes and use of incorrect viscosity oil make preventative maintenance critical.
