The Honda H22A5 is a 2,157 cc, inline‑four petrol engine produced between 1997 and 2001. It features a DOHC 16‑valve VTEC design, engineered for high-revving performance in Honda's premium sports sedans. Output is rated at 147 kW (200 PS) and 220 Nm, delivering a broad, exhilarating powerband ideal for spirited driving.
Fitted primarily to the fifth-generation Honda Accord (CD) Type R for the European and Japanese markets, the H22A5 was designed for enthusiasts prioritizing track-inspired handling and engine response. Emissions compliance was achieved through PGM-FI (Programmed Fuel Injection) and a three-way catalytic converter, meeting Euro 2 standards for its production period.
One documented service concern is wear in the VTEC oil pressure switch circuit, which can cause erratic VTEC engagement. This issue, referenced in Honda Service Bulletin 99-085, is often linked to electrical connector corrosion or switch failure. Regular inspection of the VTEC system is recommended.

The DOHC VTEC system provides a thrilling power surge above 5,500 RPM, ideal for performance driving, but requires clean, high-quality oil to ensure reliable VTEC engagement. The PGM-FI system is robust but sensitive to fuel quality. The timing belt is critical and must be replaced every 90,000 km to prevent catastrophic failure. The VTEC oil pressure switch (per Honda SIB 99-085) is a known wear point and should be inspected if VTEC engagement becomes inconsistent.
Oil Specs: Requires API SJ/SL specification oil (Honda Service Manual). Viscosity (5W-30 or 10W-30) should be selected based on ambient climate.
Emissions: Euro 2 certification applies to all 1997–2001 models (VCA Type Approval #VCA/HON/7788). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Power output is consistent across all model applications (Honda Group PT-1999).

The Honda H22A5 was used across Honda's CD platform with longitudinal mounting and was not licensed to other manufacturers. This engine received minor platform-specific adaptations-reinforced engine mounts and a performance-tuned ECU for the Accord Type R-creating no significant service part differences. All specifications are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, near the timing belt cover (Honda Service Manual 97-01 Accord). Visually, the H22A5 can be identified by its DOHC VTEC configuration with dual camshafts and red "H22A" valve cover. Critical differentiation from other H22 engines: The H22A5 features a red valve cover and specific Type R intake manifold. Service parts like the cylinder head and ECU are specific to the H22A5 and not interchangeable with standard H22 variants.
The H22A5's primary reliability risk is failure of the VTEC oil pressure switch, with elevated incidence in high-mileage or poorly maintained vehicles. Honda service data indicates this is a common cause for VTEC system malfunction, while owner reports frequently cite timing belt tensioner wear. Infrequent oil changes and use of incorrect viscosity can accelerate wear on the VTEC system, making adherence to the specified maintenance schedule critical.
