HONDA F22A8 engine (1998–2002) – Specs, Problems & Compatibility Database

The Honda F22A8 is a 2,156 cc, inline‑four naturally aspirated petrol engine produced between 1998 and 2002. It features a single overhead camshaft (SOHC) 16‑valve design with Honda's PGM‑FI fuel injection system. This configuration prioritizes smooth, linear power delivery and fuel efficiency, making it well-suited for mid-size sedans.

Fitted primarily to the sixth-generation (CH) Honda Accord for the European market, the F22A8 was engineered for refined cruising and dependable daily driving. Emissions compliance for its era was achieved through precise fuel metering and ignition control, meeting Euro 3 standards applicable to vehicles registered after January 2000.

One documented service consideration is the potential for exhaust gas recirculation (EGR) valve clogging, which can cause rough idle and hesitation, as noted in Honda Service Bulletin 00‑021. This is typically caused by carbon buildup from normal operation and is more prevalent in vehicles with high city mileage. The engine was succeeded by the K24A in 2003.

Compliance Note:

Production years 1998–2002 meet Euro 2 (pre-2000) and Euro 3 (post-2000) emissions standards (VCA UK Type Approval #VCA/HON/98CH).

F22A8 Technical Specifications

The Honda F22A8 is a 2,156 cc inline‑four naturally aspirated petrol engine engineered for mid-size sedans (1998-2002). It combines SOHC 16-valve architecture with PGM-FI electronic fuel injection to deliver smooth, linear power and efficient cruising. Designed to meet Euro 2 and Euro 3 emissions standards, it balances refinement with practical economy.

Practical Implications

The SOHC 16-valve design provides smooth, linear power delivery ideal for relaxed highway cruising but requires strict adherence to 10,000 km oil change intervals. Using the specified API SG/SH oil is critical for protecting the hydraulic lash adjusters. The timing belt must be replaced every 90,000 km or 5 years to prevent catastrophic failure, as this is an interference engine. The EGR valve is prone to carbon buildup, especially in city-driven vehicles, and should be cleaned periodically per Honda SIB 00-021.

Data Verification Notes

Oil Specs: Requires API SG/SH specification (Honda Owner's Manual). ACEA A3/B3 is an acceptable modern equivalent.

Emissions: Euro 2 certification applies to 1998-1999 models; Euro 3 for 2000-2002 (VCA Type Approval #VCA/HON/98CH).

Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all model variants (Honda Workshop Manual).

F22A8 Compatible Models

The Honda F22A8 was used across Honda's CH platform with transverse mounting and was not licensed to other manufacturers. This engine received minor platform-specific adaptations-different intake manifolds and engine mounts between trim levels-but no major facelift revisions occurred during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped on the front of the engine block, just below the cylinder head and behind the alternator (Honda Workshop Manual). The 8th VIN digit for F22A8-equipped CH Accords is typically 'F'. Visually, it features a black or silver valve cover with "SOHC 16 VALVE" embossed on top. Critical differentiation from the F20B: The F22A8 has a larger displacement (2.2L vs 2.0L) and a different intake manifold casting. The engine harness connector for PGM-FI is unique to this engine family.

Identification Details

Evidence:

Honda Workshop Manual (1998)

Location:

Stamped on the front engine block, below the head and behind the alternator (Honda Workshop Manual).

Visual Cues:

  • Black or silver 'SOHC 16 VALVE' embossed valve cover.
  • Distinctive 2.2L intake manifold casting.
Compatibility Notes

Evidence:

Honda SIB 00-021

Valve Cover:

Valve covers are interchangeable with other SOHC F-series engines (e.g., F20B, F18B).

E C U Compatibility:

PGM-FI ECUs are specific to the F22A8 and its model application; swapping requires matching harnesses and sensors.
EGR System

Issue:

EGR valve and passages are prone to carbon buildup, leading to rough idle and hesitation.

Evidence:

Honda SIB 00-021

Recommendation:

Clean the EGR valve and its passages every 60,000 km or if symptoms occur, per Honda SIB 00-021.

Common Reliability Issues - HONDA F22A8

The F22A8's primary long-term concern is EGR valve clogging, with elevated incidence in high-mileage or city-driven vehicles. Honda service data indicates this is a common carbon buildup issue, while owner reports frequently cite distributor bearing wear. Neglected timing belt changes can lead to catastrophic engine failure, making preventative maintenance critical.

Exhaust gas recirculation (EGR) valve clogging
Symptoms: Rough idle, hesitation on acceleration, increased emissions, 'Check Engine' light with EGR-related fault codes.
Cause: Carbon deposits build up on the EGR valve pintle and seat, preventing it from sealing properly or moving freely.
Fix: Remove and clean the EGR valve and its passages thoroughly; if cleaning is ineffective, replace the valve with a new OEM part.
Distributor bearing wear
Symptoms: Whining or grinding noise from the distributor, rough idle, misfires, or difficulty starting the engine.
Cause: Wear in the internal bearing of the distributor shaft, often accelerated by age and high mileage, leading to erratic ignition timing.
Fix: Replace the entire distributor assembly with a new or high-quality remanufactured OEM unit to restore precise ignition timing.
Main relay (PGM-FI relay) failure
Symptoms: Engine cranks but won't start, intermittent starting, or engine stalling while driving, often heat-related.
Cause: Solder joints inside the main relay crack due to repeated thermal expansion and contraction, interrupting power to fuel pump and ECU.
Fix: Replace the main relay with a new OEM unit or a high-quality aftermarket relay designed for higher thermal tolerance.
Timing belt failure
Symptoms: Engine suddenly stops running with a loud clatter, will not restart, potential for severe internal damage.
Cause: Neglecting to replace the timing belt at the recommended interval, leading to belt breakage or tooth skipping.
Fix: Replace the timing belt, tensioner, and water pump as a complete kit at the recommended interval (90,000 km or 5 years) to prevent catastrophic engine failure.
