OBD2 Port and Fuse Location: Specifically for the OBD2 port in your 2001 Ford Explorer, refer to Fuse #17 (20A) in the passenger compartment fuse panel. This fuse is designated for the “Cigar Lighter, Data Link Connector”. The Data Link Connector is another term for the OBD2 port. If you are experiencing issues with your OBD2 scanner not powering on or connecting, checking this 20A fuse should be one of your first steps. Additionally, Fuse #22 (20A) for the “Auxiliary Power Socket” might also be related or worth checking as power circuits can sometimes be linked.
Power Distribution Box
The power distribution box is usually located in the engine compartment. In the 2001 Ford Explorer, you’ll find it under the hood, typically near the battery or on a fender wall. This box contains fuses and relays for high-power circuits and engine management systems.

While the power distribution box might not directly house the OBD2 port fuse, understanding its layout is beneficial for overall vehicle electrical system knowledge. Fuses and relays here control critical functions like the fuel pump, ABS, and powertrain, which can indirectly affect vehicle diagnostics.
Troubleshooting with Fuses
When facing electrical problems in your 2001 Ford Explorer, checking the fuses should be a primary diagnostic step. Always consult your owner’s manual for the most accurate fuse locations and assignments as there might be slight variations depending on the specific trim and options of your vehicle.
Steps to Check a Fuse:
- Locate the Fuse Box: Identify the passenger compartment and/or power distribution box based on the descriptions above.
- Identify the Suspect Fuse: Use the diagrams and tables provided to locate the fuse related to the system you are troubleshooting (e.g., Fuse #17 for OBD2 port power).
- Visually Inspect the Fuse: Carefully remove the fuse. A blown fuse typically has a broken filament inside.
- Test with a Multimeter (Optional but Recommended): For a more accurate test, use a multimeter to check for continuity across the fuse terminals.
- Replace if Blown: If the fuse is blown, replace it with a fuse of the exact same type and amperage rating.
- If the Fuse Blows Again: If the new fuse immediately blows or blows again shortly after replacement, this indicates a more significant electrical problem in the circuit that requires professional diagnosis.
By understanding the fuse box locations and fuse assignments in your 2001 Ford Explorer, particularly the OBD2 port fuse, you can effectively troubleshoot basic electrical issues and ensure your vehicle’s diagnostic system is functioning correctly. Remember to always prioritize safety when working with automotive electrical systems and consult a qualified mechanic for complex problems.
