The Honda F22B5 is a 2,156 cc, inline‑four naturally aspirated petrol engine produced between 1994 and 1997. It features a single overhead camshaft (SOHC) 16‑valve layout and Honda's PGM‑FI fuel injection system. This configuration prioritizes low‑end torque and smooth power delivery for comfortable cruising, producing a peak output of 140 PS.

Production years 1994–1997 meet Euro 2 standards for vehicles registered from January 1997 .
The Honda F22B5 is a 2,156 cc inline‑four naturally aspirated petrol engine engineered for mid-size sedans (1994-1997). It combines SOHC 16-valve architecture with PGM-FI electronic fuel injection to deliver predictable power and strong low-end torque. Designed to meet Euro 2 emissions standards, it balances everyday usability with smooth, refined operation.

The Honda F22B5 was used across Honda's CD platform with transverse mounting and was not licensed to other manufacturers. This engine received minor platform-specific adaptations-primarily in accessory bracket positioning for the Accord-and no major facelift revisions occurred during its production run, ensuring good interchangeability within its model years. 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 F22B5's primary reliability consideration is the timing belt, with failure resulting in immediate engine damage. Honda service data indicates that neglecting the 90,000 km replacement interval is the leading cause of major engine failure. High-mileage operation and infrequent oil changes amplify wear on the valve train and main bearings, making adherence to maintenance schedules critical.
Analysis derived from Honda technical bulletins (1994-1998) and aggregated workshop repair data. 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 F22B5 is generally very reliable when its critical maintenance, especially the timing belt, is performed on schedule. Its SOHC design is simple and robust. With proper care, including regular oil changes and ignition system maintenance, these engines can easily reach 200,000 miles without major issues.
The most critical issue is timing belt failure, which destroys the engine. Other common problems include worn distributor caps/rotors causing misfires, leaking valve cover gaskets, and failing exhaust manifold gaskets. The timing belt replacement is non-negotiable for long-term reliability.
The F22B5 was used exclusively in the fifth-generation (1994-1997) European-spec Honda Accord 2.2i (CD7 chassis). It was not used in the SiR model (which had the H22A) or in other regional markets like North America.
The F22B5 has limited tuning potential compared to its DOHC siblings. Basic modifications like an intake, exhaust, and header can yield small gains. Significant power increases require internal modifications and are generally not cost-effective. Its strength lies in its smooth power delivery and reliability, not high performance.
Fuel economy is moderate for its size. Expect around 9.5-10.5 L/100km (30-27 mpg UK) in mixed driving for a stock Accord 2.2i. Highway cruising can achieve 7.5-8.0 L/100km (38-35 mpg UK), making it a comfortable cruiser for long distances.
Yes. The Honda F22B5 is an interference engine. If the timing belt fails or jumps teeth, the pistons will collide with the open valves, causing severe internal damage requiring a major engine rebuild. This underscores the absolute importance of replacing the timing belt at the recommended interval.
Honda originally specified 10W-30 mineral or semi-synthetic oil meeting API SG/SH standards. Modern high-quality 10W-30 or 5W-30 semi-synthetic or full synthetic oils meeting API SL, SM, or higher are perfectly suitable and offer better protection and longevity.
