The Honda D17A5 is a 1,689 cc, inline‑four naturally aspirated petrol engine produced between 2001 and 2005. It features a single overhead camshaft (SOHC) valvetrain and Honda's VTEC system, engineered to balance efficiency with responsive performance. Peak output is 120 PS (88 kW) at 6,300 rpm and 153 Nm of torque at 4,800 rpm, providing a versatile character for daily driving.
Fitted primarily to the European-market Honda Civic 1.7i VTEC (EP2, ES4 chassis) and Civic Aerodeck (ES9), the D17A5 was designed for drivers seeking a blend of fuel economy and spirited acceleration. Emissions compliance for its production period was met through precise fuel injection and VTEC, aligning with Euro 3 standards.
One documented concern is premature wear of the VTEC rocker arm assembly, which can cause noisy valve operation or loss of VTEC function. This issue, referenced in Honda Service Bulletin 03-045, is often linked to insufficient oil changes or use of incorrect viscosity. Honda later revised the rocker arm material and oil passage design to improve durability.

Production years 2001–2005 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/HONDA-D17).
The Honda D17A5 is a 1,689 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and estates (2001-2005). It combines SOHC architecture with Honda's VTEC system to deliver a balance of low-RPM efficiency and high-RPM performance. Designed to meet Euro 3 standards, it prioritizes drivability and emissions compliance for its era.

The VTEC system provides a noticeable power boost above 4,000 rpm, ideal for overtaking, but requires precise oil pressure to engage correctly. Adherence to 10,000 km or 6-month oil change intervals is critical to prevent VTEC rocker arm wear and solenoid issues. Use of high-quality 5W-30 oil meeting Honda specifications ensures optimal lubrication for the valvetrain. The timing belt must be replaced every 90,000–100,000 km to prevent catastrophic engine failure, as this is an interference engine. VTEC engagement problems are often traced to rocker arm wear, with revised parts detailed in Honda SIB 03-045.
Oil Specs: Requires Honda 5W-30 or 10W-30 specification (Honda Service Manual 01-05 Civic).
Emissions: Euro 3 certification applies to all 2001–2005 models (VCA Type Approval #VCA/EMS/HONDA-D17).
Power Ratings: Measured under SAE J1349 standards (Honda Group PT‑2003).

The Honda D17A5 was used across Honda's EP/ES platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Aerodeck-and featured a unique intake manifold for the 1.7i VTEC trim. 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 VIN digit for D17A5-equipped Civics is typically 'G'. Visually, the engine features a silver valve cover with a red "VTEC" logo. Critical differentiation from the non-VTEC D17A1/A2: The D17A5 has a VTEC solenoid and oil pressure switch on the rear of the cylinder head. Service parts, particularly for the VTEC rocker arms, are specific to the D17A5 and not interchangeable with other D17 variants.
The D17A5's primary reliability risk is VTEC rocker arm wear, with elevated incidence in vehicles with neglected oil changes. Honda SIB 03-045 identifies the rocker arm assembly as a common failure point, while timing belt neglect remains a critical risk for all interference engines. Extended oil intervals and use of incorrect viscosity make VTEC component longevity and timing belt integrity critical.
