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.
Fitted primarily to the seventh-generation Honda Civic (ES/EM) for the European and Japanese markets, the D17A2 was engineered for drivers prioritizing fuel efficiency without sacrificing drivability. Emissions compliance was achieved through PGM-FI (Programmed Fuel Injection) and a three-way catalytic converter, meeting Euro 3 standards for its production period.
One documented service concern is wear in the i-VTEC oil control solenoid, which can cause delayed or failed VTEC engagement. This issue, referenced in Honda Service Bulletin 03-045, is often linked to oil sludge buildup from infrequent changes. Regular oil changes with the specified viscosity are critical for preventative maintenance.

Production years 2001–2005 meet Euro 3 standards as per EU Directive 98/69/EC (VCA UK Type Approval #VCA/HON/7890).
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 i-VTEC system provides a broad, flat torque curve ideal for city driving, but requires clean, high-quality 5W-30 oil to ensure reliable solenoid operation. The PGM-FI system is robust but sensitive to fuel quality; using substandard petrol can lead to injector clogging. The timing chain is generally maintenance-free. However, the i-VTEC oil control solenoid (per Honda SIB 03-045) is susceptible to sludge buildup if oil changes are neglected, leading to VTEC engagement issues. Regular valve clearance checks every 40,000 km are recommended.
Oil Specs: Requires API SJ/SL 5W-30 specification oil (Honda Service Manual). This viscosity is mandatory for proper i-VTEC solenoid function.
Emissions: Euro 3 certification applies to all 2001–2005 models (VCA Type Approval #VCA/HON/7890). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Power output is consistent across all model applications (Honda Group PT-2003).

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.
Locate the engine code stamped on the front of the engine block, just below the exhaust manifold (Honda Service Manual 01-05 Civic). The 8th digit of the VIN for European Civic ES/EM models is typically 'D' for this engine family. Visually, the D17A2 can be identified by its black plastic valve cover with "i-VTEC" embossed on it and a single camshaft. Critical differentiation from the non-i-VTEC D17A1: The D17A2 has an i-VTEC oil control solenoid mounted on the rear of the cylinder head. Service parts like the cylinder head and ECU are specific to the D17A2 and not interchangeable with other D17 variants.
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.
