Why engine codes matter
Engine codes identify the specific variant of the 2.4-liter i-VTEC engine, which can affect parts compatibility, service procedures, and performance characteristics. They are stamped on the engine and listed in the vehicle’s documentation, helping technicians match the correct components and manuals.
Common engine codes you might encounter for this model range
- K24A1 — Most US-market 2002–2004 CR-Vs.
- K24A4 — Some export or later revisions within the 2003–2006 window.
- Other K-series variants (such as K24A2/K24A3) may appear in certain regional specifications; always verify with the engine stamping or VIN-specific service literature.
Conclusion: For the 2003 CR-V sold in the United States, the typical engine code is K24A1. However, regional variations exist, so checking the engine block sticker or stamp and cross-referencing the VIN is the best way to confirm the exact code for a specific vehicle.
How to verify the engine code on your vehicle
To confirm the exact engine code on a 2003 CR-V, locate the code stamped on the engine block itself, usually on a flat surface near the timing belt cover or front of the cylinder head. You can also cross-check the code against the vehicle’s VIN in official service manuals or Honda’s parts databases. If you have access to the owner's manual or a dealership service sheet, those sources will usually list the standard engine code for your specific VIN.

In short, the 2003 Honda CR-V’s engine is a 2.4-liter i-VTEC K-series unit, with K24A1 being the most common code for US-spec models. Always verify the exact code by checking the engine stamping and referencing the VIN to account for regional or revision differences.
