If you own or work on older Honda vehicles, you may have discovered that your standard OBD2 scanner doesn’t connect. That’s because many older Honda models use a 3-pin diagnostic port — not the modern 16-pin OBD2 interface. The OBD2 Female to HONDA-3Pin Adapter solves this problem by allowing your modern scan tools to communicate with older Honda ECUs.
In this article, we’ll explain how this adapter works, which vehicles it fits, and why it’s a must-have tool for any Honda enthusiast or mechanic.
What Is an OBD2 Female to HONDA-3Pin Adapter?
The OBD2 Female to Honda 3-Pin Adapter is a cable that connects an OBD2 scan tool to the older 3-pin diagnostic port found in many Honda vehicles manufactured in the 1990s and early 2000s.
This adapter lets you run engine diagnostics, read and clear trouble codes, and monitor real-time data — all using your standard OBD2 scanner or Bluetooth diagnostic tool.
Why You Need This Adapter for Older Honda Vehicles
Incompatible Ports Without It
Most vehicles manufactured after 1996 use a universal OBD2 port. However, many Honda models from 1992–2001 use a 3-pin proprietary port. Without this adapter, you can’t connect your modern scanner or get access to diagnostic data.
Save Time and Money on Repairs
Rather than guessing what’s wrong with your Honda or paying a dealership, this adapter empowers you to diagnose issues at home or in your own workshop using affordable tools.
Compatible Honda Models
This adapter is widely compatible with the following models:
- Honda Civic (1992–2000)
- Honda Accord (1990–2001)
- Honda CR-V (1997–2001)
- Honda Prelude, Integra, Odyssey, and more
💡 Tip: Check under your dashboard or near the ECU to see if your Honda has a 3-pin connector.

How to Use the Adapter (Step-by-Step Guide)

- Connect your OBD2 scanner or Bluetooth adapter to the female end.

⚠️ Some 3-pin systems require external 12V power. Make sure your scanner supports this or use a powered version of the adapter.
FAQs About the OBD2 Female to Honda 3-Pin Adapter
Will this work with all Honda models?
No. This adapter is designed for older models with 3-pin diagnostic ports. Newer Hondas with a standard 16-pin OBD2 port do not need this adapter.
Can I use this with Bluetooth or wireless scanners?
Yes, as long as your Bluetooth OBD2 scanner has a 16-pin male connector, it will work with this adapter.
Is any software required?
No special software is required. Just use your regular scan tool software or app (e.g., Torque, OBDFusion).
