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.

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 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.
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 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D17A5 is generally reliable with proper maintenance. Its main concerns are VTEC rocker arm wear and the critical timing belt. With regular oil changes using the correct specification and timely belt replacement, these engines can easily surpass 200,000 km. Neglecting maintenance is the primary cause of major failures.
The most common issues are VTEC rocker arm wear (causing ticking noise and P1259 code), timing belt wear leading to potential engine destruction, cracked exhaust manifolds producing a ticking noise, and deteriorated engine mounts causing excessive vibration.
The D17A5 was used exclusively in the European-market seventh-generation Honda Civic. This includes the Civic Hatchback (chassis code EP2, often badged as 1.7i VTEC) and the Civic Aerodeck (wagon, chassis code ES9) from 2001 to 2005.
Aftermarket ECU tuning is common on the D17A5 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is good for a VTEC engine. Expect around 8.0 L/100km (35 mpg UK) in mixed driving for a manual transmission model. Careful highway driving can see figures closer to 6.0 L/100km (47 mpg UK), while aggressive city driving will be higher.
Yes. The D17A5 is an interference engine. This means if the timing belt breaks or jumps teeth, the pistons will collide with the open valves, causing severe and expensive internal engine damage. This makes adhering to the timing belt replacement schedule absolutely critical.
Honda recommends 5W-30 or 10W-30 engine oil meeting their specifications. Using a high-quality synthetic or semi-synthetic oil is highly recommended, especially for the VTEC system. Oil should be changed every 10,000 km or 6 months to ensure the VTEC mechanism operates reliably.
