Does a 95 Blazer Have an OBD2 Port? A Look at OBD2 and Your Chevy Blazer

The Chevrolet Blazer has been a staple of American roads for decades, known for its ruggedness and versatility. As technology advanced, so did the Blazer, incorporating features like the On-Board Diagnostics 2 (OBD2) system. If you own a 1995 Chevrolet Blazer and are wondering about its diagnostic capabilities, this article is for you. We’ll delve into the world of OBD2 and explore whether your 95 Blazer is equipped with this essential system.

Understanding OBD2: A Brief Overview

OBD2 is a standardized system that allows mechanics and vehicle owners to communicate with a car’s computer and access valuable diagnostic information. It acts as a window into the electronic control unit (ECU), providing insights into the engine, transmission, emissions system, and more.

The OBD2 system became mandatory for all cars and light trucks sold in the United States in 1996. This means that if your 1995 Chevrolet Blazer was manufactured for the US market, it is highly likely to have an OBD2 port.

Locating the OBD2 Port on Your 95 Blazer

The OBD2 port is usually located under the dashboard on the driver’s side. It is a female, 16-pin connector that resembles a trapezoid.

Expert Insight: “Even though 1996 was the year OBD2 became mandatory, many manufacturers, including Chevrolet, started incorporating it into their 1995 models,” says automotive engineer and OBD2 expert, Mark Williams.

What if I Can’t Find the Port?

If you’re having trouble finding the OBD2 port in your 95 Blazer, consult your owner’s manual. It should provide a diagram or instructions on its location.

The Benefits of Having an OBD2 Port

The OBD2 port allows you to:

Retrieve Diagnostic Trouble Codes (DTCs): When your check engine light illuminates, the OBD2 system stores a trouble code in the ECU. You can use an OBD2 scanner to retrieve these codes and understand the underlying issue.
Monitor Real-Time Engine Data: OBD2 scanners provide live data streams from various sensors, including engine speed, coolant temperature, and oxygen sensor readings. This information can be invaluable for diagnosing problems or monitoring engine performance.
Reset the Check Engine Light: Once you’ve addressed the problem that triggered the check engine light, you can use an OBD2 scanner to clear the code and turn off the light.

Choosing the Right OBD2 Scanner

OBD2 scanners come in various types, from basic code readers to advanced professional-grade tools. For most 95 Blazer owners, a basic scanner that can read and clear codes is sufficient.
