What is an OBD2 Port and What Does it Do?

OBD stands for On-Board Diagnostics, and the OBD2 port is a standardized 16-pin connector found in most vehicles manufactured after 1996. It provides access to data from your car’s Engine Control Unit (ECU) and other control modules.

Think of it as your car’s communication hub. By connecting a compatible OBD2 scanner, you (or a mechanic) can:

Retrieve Diagnostic Trouble Codes: When your car’s “Check Engine” light illuminates, the OBD2 port allows you to read the error codes stored in the ECU, identifying the source of the problem.
Monitor Real-Time Engine Data: View live sensor data such as engine speed, coolant temperature, oxygen sensor readings, and more, giving you valuable insights into your engine’s performance.
Reset the Check Engine Light: After addressing a problem, you can use an OBD2 scanner to clear the codes and turn off the “Check Engine” light.
Conduct Emissions Testing: OBD2 ports play a crucial role in emissions testing, ensuring your vehicle meets environmental regulations.

Tips for Locating the Port:
