The On-Board Diagnostics II (OBD2) port in your 2018 Ford Explorer is a crucial access point for vehicle diagnostics and maintenance. Whether you’re a seasoned DIY mechanic or a Ford Explorer owner looking to understand your vehicle better, knowing the location and function of this port is essential. This guide will clearly explain where to find the OBD2 port in your 2018 Ford Explorer and why it’s so important.
Locating the OBD2 Port in Your 2018 Ford Explorer
Finding the OBD2 port in a 2018 Ford Explorer is generally straightforward. Ford, like most vehicle manufacturers, standardizes the location for easy access. You can typically locate the OBD2 port for your 2018 Ford Explorer in the following area:
- Under the Dashboard: The most common location is beneath the dashboard on the driver’s side.
- Near the Steering Column: Look for it in the area around and below the steering column. It’s usually within easy reach from the driver’s seat.
- Knee Area: Specifically, check the paneling in the knee area of the driver. You might need to crouch down slightly to get a clear view.
The OBD2 port is usually trapezoidal in shape with 16 pins. It’s designed for easy access, so you shouldn’t need any tools to locate or reach it. In most cases, it’s not hidden behind any panels, though it may be recessed slightly.

Why is the OBD2 Port Important for Your 2018 Ford Explorer?
The OBD2 port serves as a communication interface between your 2018 Ford Explorer’s computer system and diagnostic tools. It’s a standardized system that has been mandatory in vehicles sold in the United States since 1996. Here’s why it’s so important:
- Check Engine Light Diagnostics: When your “Check Engine Light” illuminates, the OBD2 port is your first step in understanding the problem. Mechanics and DIYers can plug in an OBD2 scanner or code reader to retrieve diagnostic trouble codes (DTCs). These codes pinpoint potential issues within the engine, transmission, emissions system, and more.
- Emissions Testing: Many states and regions require emissions testing for vehicle registration. The OBD2 port is used to quickly check if your 2018 Ford Explorer’s emissions systems are functioning correctly.
- Vehicle Health Monitoring: Beyond just error codes, OBD2 scanners can provide real-time data about your Ford Explorer’s performance. This can include engine temperature, RPM, speed, sensor readings, and other vital information. This data is invaluable for preventative maintenance and performance monitoring.
- DIY Car Repairs and Maintenance: For those who prefer to handle their car maintenance, the OBD2 port empowers you to diagnose problems yourself before taking your vehicle to a mechanic. This can save time and money by providing insights into necessary repairs.
- Access to Advanced Features: Some advanced OBD2 scanners and software can even allow you to access and customize certain vehicle settings, though this is typically for more advanced users and requires caution.

Using Your 2018 Ford Explorer OBD2 Port
Using the OBD2 port is simple. You’ll need an OBD2 scanner or code reader, which are readily available online and in auto parts stores.
- Locate the Port: First, ensure your 2018 Ford Explorer is turned off. Locate the OBD2 port as described earlier.
- Plug in the Scanner: Connect your OBD2 scanner to the port. It should plug in easily and securely.
