The Toyota 2AZ — FE is a 2,362 cc, inline‑four petrol engine produced between 2000 and 2015. It features an aluminium block and head with a chain‑driven DOHC valvetrain and VVT‑i (Variable Valve Timing‑intelligent). This design balances refinement and efficiency, delivering outputs between 118–130 kW (160–177 PS) and torque figures of 220–224 Nm, suitable for smooth, confident performance in mid‑size vehicles.
Fitted to models like the Camry, RAV4, and Avensis, the 2…

Production years 2000–2005 meet Euro 4 standards; 2006–2015 models meet Euro 5 compliance depending on market .
The Toyota 2AZ-FE is a 2,362 cc inline‑four petrol engineered for mid‑size sedans and SUVs (2000-2015). It combines VVT‑i with a lightweight aluminium construction to deliver smooth, linear power delivery and respectable fuel economy. Designed to meet Euro 4 and Euro 5 standards, it balances everyday drivability with low running costs.

The Toyota 2AZ-FE was used across Toyota's MC/XA platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the RAV4 and specific intake manifolds for the Camry-and from 2009 the facelifted Avensis models adopted minor ECU revisions for improved emissions, 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 2AZ-FE's primary documented concern is potential oil consumption in specific production runs, with elevated incidence in high-mileage or poorly maintained vehicles. Toyota TSB EG-0112-06 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
Generally, yes. The 2AZ-FE is mechanically robust with a durable timing chain. Its main weakness is potential oil consumption in specific batches and the VVT-i oil line issue in 2007-2009 Camry/RAV4. With regular oil changes using the correct 5W-30 oil and addressing known issues, it can reliably exceed 250,000 km.
The most common issues are excessive oil consumption (specific batches), VVT-i oil line failure (2007-2009 Camry/RAV4), water pump leaks, and ignition coil failures. The oil line issue is critical and can cause engine seizure if ignored. These are well-documented in Toyota service bulletins.
The 2.4L 2AZ-FE was used in the Toyota Camry (2001-2011), RAV4 (2000-2012), Avensis (2003-2015), and Previa/Estima (2000-2006). It was a popular engine for Toyota's global mid-size car and SUV lineup during this period, offering a good balance of power and efficiency.
The 2AZ-FE has limited tuning potential as it's naturally aspirated. ECU remaps can yield minor gains (5-15 kW), but significant power increases require forced induction, which is complex. Most tuning focuses on improving throttle response and mid-range torque rather than peak power.
Fuel economy is average for its size and era. In a Camry or RAV4, expect around 8.5-10.0 L/100km (28-33 mpg UK) combined in real-world driving. Highway cruising can be around 7.0 L/100km (40 mpg UK), while city driving may be 11.0-12.0 L/100km (23-25 mpg UK). Figures vary by model, year, and transmission.
Yes. The 2AZ-FE 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 SN or ILSAC GF-5 (or newer) standards. Using 'Toyota Genuine Motor 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 VVT-i system and timing chain.
