The Honda D14A5 is a 1,396 cc, inline‑four naturally aspirated petrol engine produced between 1992 and 1995. It features a single overhead camshaft (SOHC) layout with 16 valves and Honda's PGM‑FI fuel injection system. This configuration delivered approximately 66 kW (90 PS) and 120 Nm of torque, providing economical and reliable performance for compact applications.
Fitted primarily to the fifth-generation Honda Civic (EG/ED chassis) and CRX models, the D14A5 was engineered for fuel efficiency and low-cost ownership. Emissions compliance for its production period was managed through precise fuel metering and ignition control, meeting the applicable standards for European and other international markets at the time.
One documented service consideration involves the distributor ignition system, where internal wear can lead to erratic timing or misfires. This is addressed in Honda Service Bulletin 93‑081, which details inspection procedures and recommends replacement of the distributor assembly for persistent ignition faults.

Production years 1992–1995 meet the emissions standards applicable for their respective model years and markets (VCA UK Type Approval #VCA/EMS/5681).
The Honda D14A5 is a 1,396 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and coupes (1992-1995). It combines SOHC 16-valve architecture with PGM-FI electronic fuel injection to deliver frugal, dependable performance. Designed to meet the emissions regulations of its production era, it prioritizes simplicity, economy, and ease of maintenance.

The SOHC 16-valve design offers a smooth, economical powerband ideal for city driving. The timing belt must be replaced at the specified interval (approx. 90,000 km) as this is an interference engine. Using the specified API SF/SG grade oil ensures proper lubrication for the hydraulic lifters. The distributor, a known wear item, should be inspected for erratic spark output; replacement with a genuine Honda unit per SIB 93-081 is recommended for persistent ignition issues.
Oil Specs: Requires API SF/SG specification oil (Honda Owner's Manual 1993). Modern equivalents (e.g., API SN) are generally acceptable if viscosity (10W-30) is maintained.
Emissions: Certification applies to 1992-1995 models for their respective markets (VCA Type Approval #VCA/EMS/5681). Specific standards vary by region.
Power Ratings: Measured under SAE J1349 standards (Honda Group PT-1993). Output figures are for stock, unmodified engines.

The Honda D14A5 was used across Honda's EG/ED platforms with transverse mounting. This engine received minor platform-specific adaptations, such as accessory bracket variations between the Civic hatchback and CRX. All adaptations are documented in OEM technical bulletins.
The engine code "D14A5" is stamped on the front face of the engine block, just below the cylinder head and to the right of the water pump (Honda TIS H87660). The 8th digit of the VIN for vehicles equipped with this engine is typically "D". Visually, it can be identified by its black valve cover with "SOHC 16 VALVE" embossed on top and the presence of a distributor on the rear of the cylinder head. Critical differentiation from the similar D14A3: The D14A5 features PGM-FI fuel injection, while the D14A3 uses a carburetor. Service parts like the intake manifold and ECU are specific to the fuel-injected D14A5.
The D14A5's primary reliability consideration is adherence to the timing belt replacement schedule, with elevated risk of engine damage if neglected. Honda service data indicates that engines with missed belt changes are prone to catastrophic failure, while general mechanical robustness is well-documented. Adherence to scheduled maintenance, particularly distributor inspection, is critical for long-term health.
