The Honda D14A4 is a 1,396 cc, inline‑four naturally aspirated petrol engine produced between 1992 and 1995. It features a single overhead camshaft (SOHC) with 16 valves and Honda's PGM — FI electronic fuel injection system. This design prioritized fuel efficiency and low — cost ownership for its era, producing 63 kW (86 PS) and 121 Nm of torque.

Production years 1992–1995 meet the emissions standards applicable to their respective markets (e.g., US EPA Tier 0, Japanese 1988 regulations).
The Honda D14A4 is a 1,396 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks (1992-1995). It combines SOHC 16-valve architecture with PGM-FI fuel injection to deliver frugal, dependable performance and smooth low-RPM operation. Designed to meet the emissions standards of its era, it prioritizes economy and reliability.

The Honda D14A4 was used across Honda's EG platform with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds for Civic vs. CRX variants-and no significant facelift revisions occurred during its production run. 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 D14A4's primary reliability risk is distributor ignition module failure, with elevated incidence in vehicles subjected to high ambient temperatures. Honda SIB 93-055 documents this issue, while owner reports frequently cite it as a source of drivability problems. Adherence to the critical 90,000 km timing belt interval is paramount for engine survival.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D14A4 is a simple and generally robust engine. Its main long-term concerns are the distributor ignition module and the critical timing belt. With the distributor replaced preventatively and the timing belt changed religiously every 90,000 km, these engines can easily surpass 250,000 km. The SOHC head is also notably durable and easy to work on.
The most frequent issues are failing distributor ignition modules (causing misfires), neglected timing belt failures (causing engine destruction), leaking valve cover gaskets, and worn water pumps. These are well-documented in Honda service literature and owner communities.
The D14A4 was primarily used in the fifth-generation Honda Civic (EG chassis, 1992-1995) in DX and LX trims. It was also used in the base model of the fifth-generation Honda CRX (EG chassis) for the same period in certain markets.
Minor gains are possible. The stock ECU can be chipped, and performance exhausts or intake manifolds can be fitted. However, the SOHC 16-valve head is a significant airflow bottleneck. Major power increases require extensive modification or an engine swap to a more performance-oriented variant like the B16A.
For a 1.4L from the early 90s, it's excellent. Expect around 8.0 L/100km (35 mpg US) in city driving and 6.0 L/100km (47 mpg US) on the highway in a Civic hatchback. Real-world combined figures typically fall between 38-42 mpg US, making it a very economical choice.
Yes. The D14A4 is an interference engine. If the timing belt fails, the pistons will collide with the open valves, causing severe internal engine damage. Adhering to the 90,000 km timing belt replacement interval is absolutely critical.
Honda originally specified SAE 10W-30 with an API SH rating. Modern multi-grade oils like 10W-30 or 5W-30 meeting API SN or higher are perfectly suitable and offer better protection. Always use a quality brand and change it regularly (every 7,500 km).
