The OBD2 port, short for On-Board Diagnostics, is a standardized 16-pin connector found in most vehicles manufactured after 1996. It acts as the gateway to your Hyundai Elantra’s engine control unit (ECU), providing valuable data about your car’s performance.

The OBD2 port allows you to:

Read and clear diagnostic trouble codes (DTCs): These codes are triggered when the ECU detects an issue within your car’s systems.
Monitor real-time engine data: This includes parameters like engine speed, coolant temperature, oxygen sensor readings, and more.
Perform emissions testing: Many states require an OBD2 scan as part of their vehicle emissions testing procedures.

Understanding how to utilize the OBD2 port can empower you to diagnose problems, potentially saving you costly trips to the mechanic.

Here’s a step-by-step guide to locating the port:

Sit in the driver’s seat and look beneath the steering wheel.
Scan the area beneath the dashboard, focusing on the area around the pedals and the fuse box.
The OBD2 port is a trapezoidal-shaped connector with 16 pins. It is usually covered by a plastic cap.
