OBD2 Code P0506 in 2005 Ford Expedition: Reverse Failure and Drive Performance Issue

Model: 2005 Ford Expedition Fault Code: P0506 Posted: 2015-11-25 23:26

I recently connected my OBD2 scanner to my 2005 Ford Expedition, and the only fault code detected was P0506. The vehicle is now completely unable to reverse, and on Drive, it will not move unless I press down heavily on the gas pedal. This behavior is concerning as it affects both safety and drivability. The OBD2 code P0506 indicates a problem with engine idle speed or fuel delivery, which may be contributing to this issue.
