The Honda F23A2 is a 2,254 cc, inline‑four naturally aspirated petrol engine produced between 1998 and 2002. It features a single overhead camshaft (SOHC) with four valves per cylinder, engineered for smooth, torque — rich performance in executive applications. Peak output is 150 PS (110 kW) at 5,700 rpm and 206 Nm of torque, prioritizing low — to — mid range drivability for comfortable cruising.
Fitted primarily to the sixth — generation Honda Accord (CF) and the Acura CL (…

Production years 1998–2002 meet Euro 3 emissions standards for applicable markets (Honda Emissions Certification Docs, EU Regulation (EC) No 715/2007 Annex I).
The Honda F23A2 is a 2,254 cc inline‑four naturally aspirated petrol engine engineered for mid-size sedans and coupes (1998-2002). It combines SOHC 16-valve design with multi-point fuel injection to deliver smooth, linear power delivery and efficient operation. Designed to meet Euro 3 emissions standards, it prioritizes refinement and everyday drivability.

The Honda F23A2 was used across Honda's CF platform with transverse mounting. This engine received no major facelift revisions during its production run, ensuring broad parts interchangeability. All specifications are documented in OEM technical bulletins.
The F23A2's primary maintenance-critical item is its timing belt, with failure resulting in total engine destruction. Honda service data indicates strict adherence to replacement intervals is paramount. While generally robust, high-mileage units may exhibit increased oil consumption, a documented characteristic in Honda service bulletins, making regular oil level checks essential.
Analysis derived from Honda technical bulletins (1998-2002) and aggregated owner-reported failure data (2002-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the F23A2 is generally very reliable when properly maintained. Its main critical item is the timing belt; failure to replace it on schedule will destroy the engine. With regular oil changes and adherence to the service schedule, these engines are known for longevity, though high-mileage units may consume more oil.
The most frequent issues are oil leaks from the valve cover gasket and the distributor shaft seal. The critical concern is timing belt failure. Some high-mileage engines may exhibit increased oil consumption due to normal wear, a characteristic documented by Honda.
The F23A2 was used in the European market sixth-generation Honda Accord (CF chassis) from 1998 to 2002 and the US-market Acura CL (facelift) from 1999 to 2000. It was marketed as the 2.3i variant.
Yes, the F23A2 responds well to basic tuning. Common modifications include an intake, exhaust, and ECU remap, yielding modest gains. Swapping in camshafts from the higher-output F23A1 is a popular upgrade. Its robust bottom end makes it a solid platform for enthusiasts.
Fuel economy is good for its size. Expect around 9.5-10.5 L/100km (30-27 mpg UK) in mixed driving for a manual transmission Accord. Highway cruising can see figures as low as 7.5 L/100km (38 mpg UK), depending on driving style and conditions.
Yes. The F23A2 is an interference engine. If the timing belt breaks or jumps time, the pistons will collide with the open valves, causing severe internal damage that requires a costly rebuild or replacement.
Honda recommends API SJ/SL grade oil. The viscosity (5W-30 or 10W-30) depends on the climate. Using high-quality oil and changing it regularly (every 10,000 km or 6 months) is crucial for engine health, especially to manage potential oil consumption in high-mileage units.
