The OBD-II port on a Honda Civic is typically located under the driver’s side dash in the footwell, behind a small removable cover near knee height. It’s a standard 16-pin connector used for diagnostics.
In this article, we walk through where to look on most Civics, how to identify the port, and what to do if you can’t locate it. The exact spot is usually the same from recent generations, but a tiny panel or trim piece may hide it in some models.
Location and how it usually looks
For most Honda Civics, the port sits in the driver's footwell under the dash, to the left of the steering column. It is often concealed by a small rectangular panel or trim piece that you can pry open with a fingernail or small tool. The port itself is a standard 16-pin SAE J1962 connector.
To locate quickly, use these steps.
- Park safely and turn off the engine; remove the key from the ignition.
- Sit in the driver's seat and look under the dash on the left side of the steering column, near knee height.
- Look for a small removable panel or trim piece; the OBD port is behind or inside this panel.
- Open the panel to reveal the 16-pin OBD-II connector, which is shaped to fit a standard diagnostic tool.
If you still can’t find it after examining the driver’s footwell, check for a slightly different panel near the fuse box area or consult the owner’s manual for your exact year and trim. A dealership or a repair shop can also show you in person.
Notes by model year and generation
Consistency across modern Civics
Across most recent Honda Civics, the OBD-II port remains in the driver’s footwell on the left side of the dash. It’s designed to be accessible from the driver’s seat and is typically hidden behind a small panel for a clean interior look.
What to do if you still can’t locate it
If you can’t locate the port after these checks, consult your owner’s manual for the exact location for your year and trim. You can also ask a dealership service department to point it out in person or use a local auto parts store’s guidance to identify the port by feel and shape.
Summary
For most Honda Civics, the OBD-II diagnostic port is found in the driver’s footwell, under the dash to the left of the steering column, usually behind a small removable panel. It’s the standard 16-pin connector used for emissions and diagnostics. If you have trouble finding it, refer to the owner’s manual or seek in-person guidance from a dealer or service professional. The port is there to keep vehicle diagnostics accessible while maintaining a clean interior.
