Where is the Ford F150 OBD port location?

I have a 2018 Ford F150, and I bought an OBD-II scanner to figure out why my engine light came on, but I can’t find where to plug it in. Where should I look to find it?

The Ford F150 OBD port location is under the dashboard on the driver’s side. You’ll find it below the steering column near the middle of the driver’s footwell.
The OBD II port on your F150 is essential and used to diagnose problems with your truck. Its primary role is for vehicle diagnostics, but it’s also involved in other actions, including:
  • Diagnosing engine faults
  • Engine control unit (ECU) reprogramming
  • Vehicle telematics (when attached to the OBD port)
If you’re using an OBD-II scanner to diagnose a problem with your Ford F150, here’s what you’ll need to do:
  • Start your F150 to power the scanner
  • If needed, enter any vehicle-specific information requested (some tools ask for the VIN)
  • Press Scan on the code reader to check for engine codes; follow the directions on the screen
  • The screen will record any error codes
  • First character: The vehicle part affected by the problem
  • Second character: Generic code or issued by the manufacturer
  • Third character: Provides specific information about what area of the vehicle is affected
  • Last character: Identifies the exact problem
