Where is the OBD2 Port Location on a Miata NB?

The Mazda Miata NB is a popular sports car known for its fun-to-drive nature and reliable performance. However, like any vehicle, you may encounter issues that require troubleshooting using an OBD2 scanner. Knowing where the OBD2 port is located on your Miata NB is crucial for accessing diagnostic information and codes.

Finding the OBD2 Port on a Miata NB

The OBD2 port on a Miata NB (1999-2005) is located under the dashboard, on the driver’s side, near the steering column. It’s a 16-pin connector that resembles a trapezoid shape. To find it, follow these steps:

1. Locate the driver’s side knee bolster. This is the plastic panel located below the steering wheel on the driver’s side.
2. Remove the knee bolster. This is usually held in place by clips or screws. You might need to pull on it gently to release it.
3. Look for a 16-pin connector. You’ll find the OBD2 port directly below the steering column, near the fuse box.
