The Honda D17A2 is a 1,668 cc, inline‑four petrol engine produced between 2001 and 2005. It features a SOHC 16‑valve design with Honda's i — VTEC (intelligent Variable Valve Timing and Lift Electronic Control) system, optimizing valve timing for both low — end torque and high — RPM efficiency. Output is rated at 90 kW (122 PS) and 155 Nm, making it suitable for compact applications.

Production years 2001–2005 meet Euro 3 standards as per EU Directive 98/69/EC .
The Honda D17A2 is a 1,668 cc inline‑four petrol engine engineered for compact hatchbacks and sedans (2001-2005). It combines SOHC i-VTEC technology with PGM-FI fuel injection to deliver responsive low-end torque and efficient highway cruising. Designed to meet Euro 3 emissions standards, it balances spirited performance with daily reliability.

The Honda D17A2 was used across Honda's ES/EM platform with transverse mounting and was not licensed to other manufacturers. This engine received platform-specific adaptations-revised engine mounts for the Civic and a different intake manifold for JDM variants-creating minor service part differences. 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 D17A2's primary reliability risk is failure of the i-VTEC oil control solenoid, with elevated incidence in vehicles subjected to infrequent oil changes. Honda service data indicates this is a common cause for i-VTEC system malfunction, while owner reports frequently cite exhaust manifold gasket leaks. Use of incorrect oil viscosity can accelerate solenoid wear, making adherence to the specified maintenance schedule critical.
Analysis derived from Honda technical bulletins (2001-2005) and aggregated European owner club failure reports (2005-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the D17A2 is generally reliable long-term when properly maintained. Its SOHC i-VTEC design is less complex than DOHC VTEC engines, contributing to its durability. The main concerns are the i-VTEC solenoid and exhaust manifold gasket, both of which are inexpensive and straightforward to replace. Regular oil changes with the correct 5W-30 viscosity are key to preventing solenoid issues.
The most frequent issues are i-VTEC oil control solenoid failure (causing P1259 code and loss of VTEC), exhaust manifold gasket leaks causing ticking noises, and neglected valve clearance adjustments. Less common are issues with engine mounts or the thermostat housing.
The D17A2 was primarily used in the seventh-generation Honda Civic (chassis codes ES1, ES4, EM2) for the European and Japanese markets from 2001 to 2005. It was fitted to the 1.7i VTEC trim level. It was not used in the North American market Civic, which received different engine options.
Yes, the D17A2 responds well to basic modifications. A performance exhaust header, cold air intake, and ECU remap can yield gains of 10-15 kW. More advanced builds involve head porting or camshaft upgrades, but the SOHC design limits its ultimate potential compared to DOHC engines. Its bottom end is robust for moderate power increases.
Fuel economy is very good. In a manual transmission Civic, expect around 7.8 L/100km in the city and 5.6 L/100km on the highway, translating to approximately 36-42 mpg (UK) combined. Actual figures depend heavily on driving style, vehicle condition, and adherence to maintenance schedules.
Yes. The Honda D17A2 is an interference engine. If the timing chain fails (a rare occurrence), the pistons will collide with the valves, causing catastrophic engine damage. Fortunately, the timing chain is designed to last the engine's lifetime with proper oil maintenance.
Honda mandates the use of 5W-30 engine oil meeting API SJ or SL specifications. Using this exact viscosity is crucial for the proper operation of the i-VTEC system. Full synthetic oil is highly recommended for optimal protection and longevity, especially given the sensitivity of the i-VTEC solenoid to oil quality.
