The On-Board Diagnostics II (OBD2) port in your 2003 Honda Odyssey is a crucial interface for accessing your vehicle’s computer system. Whether you’re trying to diagnose a check engine light, understand sensor readings, or perform emissions testing, knowing the location of your OBD2 port is the first step. This article will guide you directly to where you can find it in your 2003 Honda Odyssey, ensuring you can quickly connect your diagnostic tools and get the information you need.
The OBD2 port, standardized across most vehicles manufactured after 1996, is designed to be easily accessible. For the 2003 Honda Odyssey, the most common location is under the dashboard on the driver’s side.
Specifically, you should check the area beneath the steering wheel and to the left. You’ll be looking for a trapezoid-shaped, 16-pin connector. It’s usually black, but sometimes can be another dark color, and is designed to be quite durable.

In the 2003 Honda Odyssey, the OBD2 port is often positioned in the vicinity of the fuse box and hood release lever. You might need to crouch down and look up under the dash to get a clear view. It is not hidden behind a panel, but openly accessible for easy connection.
While the under-dash, driver’s side location is the primary spot, there can be slight variations. Although less common for a 2003 Honda Odyssey, if you don’t find it immediately under the steering wheel, there are a couple of alternative areas to quickly check.
One alternative location, although less likely in this model year, is in the center console area on the passenger side. This was mentioned in the original forum thread for earlier models, so it’s worth a quick glance just to be thorough.

Another less probable but still possible location to quickly check is within the side kick panels in the footwells on either the driver or passenger side. Again, this is less typical for a 2003 Odyssey but easy to check with a quick look.
Once you’ve located the OBD2 port, connecting your scan tool is straightforward. Simply align the connector and push firmly until it’s securely in place. Turn your vehicle’s ignition to the ‘ON’ position (without starting the engine unless your scan tool requires it), and you’ll be able to begin reading diagnostic data.
In summary, for your 2003 Honda Odyssey, you will almost certainly find the OBD2 port located under the dashboard on the driver’s side, beneath the steering wheel. This standardized location makes diagnosing your vehicle’s health simpler and more accessible for both car owners and professional mechanics. By quickly locating this port, you can take the first step in understanding and resolving any potential issues your vehicle might be experiencing.
