The OBD-II diagnostic port on a 1998 Honda Accord is located under the driver's side dashboard, to the left of the steering column, usually behind a small removable panel in the knee-area. This standard 16-pin connector is used to read engine codes and monitor vehicle systems.
Location basics
To begin, look for the port in the lower dash area on the driver's side. In most Accords from this era, a small plastic cover hides the port and must be removed to access the connector.
Common hiding spots
- Under the steering column, near knee level on the driver’s side dash.
- Behind a removable panel on the lower dash, close to the left edge of the steering wheel.
- Near the fuse box area or the hood release lever location on the left side of the dash.
These locations reflect the typical layout for a 1998 Accord; some trims or aftermarket dash covers may shift the exact position slightly, but the port remains in this general region.
Accessing and using the port
Once you’ve located the panel, remove it to reveal the 16-pin OBD-II connector. Ensure the ignition is off before connecting your scan tool, and follow the tool’s instructions for reading codes or monitoring live data.
What the port looks like
The OBD-II port is a 16-pin connector housed in a small, recessed black or dark gray connector. It’s designed to accept standard OBD-II scanners and is oriented to fit only one way.
- Open or detach the dash cover to expose the port.
- Plug the 16-pin scanner connector into the port.
- Turn the ignition to ON (engine off) if required by your tool, then follow the device prompts to retrieve codes or data.
- When finished, reattach the cover to keep dust and moisture out.
Most users will find compatibility with a wide range of OBD-II scanners since the 1996-and-newer Accord supports standard J1962 wiring.
Summary
For a 1998 Honda Accord, the OBD-II port is located under the driver's side dashboard to the left of the steering column, typically behind a small removable knee-area panel. Access it by removing the cover, plug in a 16-pin scanner, and follow the device instructions. If you can’t locate it, consult the owner’s manual or a service manual for your specific trim and production year.
