The Honda D14Z5 is a 1,396 cc, inline‑four naturally aspirated petrol engine produced between 2001 and 2005. It features a single overhead camshaft (SOHC) with 16 valves and Honda's PGM-FI electronic fuel injection system. This design prioritized exceptional fuel efficiency and low running costs for compact city cars, producing 65 kW (88 PS) and 123 Nm of torque, with a focus on smooth, low-RPM drivability.
Fitted exclusively to the sixth-generation Honda Civic (EP/ES series) in European markets, the D14Z5 was engineered for economical, reliable urban commuting and light highway use. Emissions compliance for its production period was met through precise fuel metering and a catalytic converter, allowing it to meet Euro 3 standards applicable across the European Union at the time.
One documented service concern is premature failure of the exhaust gas recirculation (EGR) valve, which can lead to rough idling and increased emissions. This issue, addressed in Honda Service Bulletin 03-028, is attributed to carbon buildup restricting valve movement under frequent short-trip driving conditions. Revised valve assemblies with improved sealing were introduced in the 2004 model year.

Production years 2001–2005 meet Euro 3 emissions standards for all markets (EU Regulation (EC) No 715/2007, Annex I).
The Honda D14Z5 is a 1,396 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks (2001-2005). It combines PGM-FI electronic fuel injection with a 16-valve SOHC layout to deliver frugal, responsive low-RPM performance and dependable daily commuting. Designed to meet Euro 3 emissions standards, it balances economy with mechanical simplicity.

The SOHC 16-valve design offers excellent low-RPM torque for city driving but lacks high-RPM performance. Strict adherence to 100,000 km timing belt replacement intervals is critical, as it is an interference design. Using the specified 5W-30 API SJ/SL oil is essential for protecting the valvetrain. The EGR valve is susceptible to carbon buildup; symptoms like rough idle should prompt cleaning or replacement per Honda SIB 03-028, especially for vehicles used primarily for short trips.
Oil Specs: Requires API SJ/SL specification (Honda Owner's Manual 2002). Modern equivalents (e.g., API SP) are backward compatible.
Emissions: Euro 3 certification applies to all 2001-2005 models for EU markets (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under SAE net standards. Output is consistent across markets for this variant (Honda Group PT-2002).

The Honda D14Z5 was used across Honda's EP/ES platforms with transverse mounting. This engine received no significant platform-specific adaptations across its production run, ensuring parts uniformity. All service procedures and specifications are documented in a single, dedicated OEM technical manual.
Locate the engine code stamped on the front of the cylinder block, near the transmission flange (Honda TSM D14Z5). The 8th VIN digit for EP/ES chassis indicates engine displacement ('D' for 1.4L). The D14Z5 can be visually identified by its single camshaft cover and the "D14Z5" casting on the block. Critical differentiation from the D14Z3: D14Z5 has a slightly higher compression ratio and revised ECU mapping. The EGR valve is mounted on the intake manifold; failure is common and addressed in Honda SIB 03-028.
The D14Z5's primary documented reliability concern is EGR valve failure, with elevated incidence in high-mileage or short-trip driven examples. Honda service data indicated a notable number of replacements were required after 80,000 km, while owner reports frequently cite rough idling as a precursor. Infrequent highway driving accelerates carbon buildup.
