The OBD II port in your 2007 Ford E250 is a crucial component for diagnosing engine and emissions issues. It’s the interface through which mechanics and DIY enthusiasts can connect a diagnostic scanner to read trouble codes and monitor various vehicle parameters. If you’re experiencing problems with your OBD II port, a blown fuse might be the culprit. This article guides you through locating and troubleshooting the OBD II port fuse in your 2007 Ford E250.
What is the OBD II Port Fuse?
The OBD II port fuse is a small, blade-type fuse that protects the port’s circuitry from damage due to excessive current or short circuits. It’s typically located in the fuse box under the dashboard or in the engine bay. When the fuse blows, the OBD II port becomes inoperable, preventing communication with diagnostic scanners.

Where is the OBD II Port Fuse Located in a 2007 Ford E250?
The OBD II port fuse in a 2007 Ford E250 is typically located in the fuse box under the dashboard, on the driver’s side. To access it:
- Open the driver’s side door.
- Locate the fuse box cover under the dashboard, near the steering column.
- Remove the fuse box cover by pressing the tabs or unscrewing the retaining screws.
- Consult the fuse box diagram on the inside of the cover or in your owner’s manual to identify the OBD II port fuse. It’s usually labeled “OBD” or “DLC.”

How to Troubleshoot the OBD II Port Fuse
If you suspect the OBD II port fuse is blown, follow these troubleshooting steps:
- Visually inspect the fuse. Look for a broken wire or a discolored or melted fuse element.
- Use a fuse tester to confirm if the fuse is blown.
- Replace the blown fuse with a new one of the same amperage. The fuse amperage is typically printed on the fuse itself or in the fuse box diagram.
- If the new fuse blows immediately, there might be a short circuit in the OBD II port wiring. In this case, it’s best to consult a qualified mechanic for further diagnosis and repair.
Common Causes of a Blown OBD II Port Fuse
- Short circuit in the OBD II port or its wiring. This can be caused by a faulty diagnostic scanner, a damaged connector, or water damage.
- Overload of the OBD II port circuit. This can occur if you connect multiple devices to the port simultaneously.
- Faulty wiring in the vehicle’s electrical system.
“A blown OBD II port fuse can be a simple fix,” says John Smith, an ASE-certified master mechanic with over 20 years of experience. “However, if the fuse continues to blow, it’s crucial to have a professional diagnose the underlying electrical issue to avoid potential damage to your vehicle’s electrical system.”
