The OBD2 (On-Board Diagnostics, second generation) port is a standardized 16-pin connector found in most vehicles manufactured after 1996, including the 1998 Toyota Avalon.

This data is invaluable for diagnosing problems, understanding performance issues, and ensuring your Avalon runs smoothly. The OBD2 port is the gateway to understanding your car’s health. Having easy access and knowing its location is essential for any car owner.

Typically, the OBD2 port in a 1998 Toyota Avalon is located under the driver’s side dashboard, near the steering column. It’s usually positioned above the pedals and may be partially concealed by a plastic cover.
