Where is the OBD-II port located on my Ford Bronco?

On the Ford Bronco, the 16-pin DLC diagnostic connector is located Beneath steering wheel lower shroud. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.

Can I safely drive my Ford Bronco with code P0463?

Yes. Engine runs normally, but fuel gauge will be inaccurate or pegged at EMPTY / FULL. Given that P0463 carries a Low severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
