what you need to do, and this is not guaranteed, because i have access to a ford (ids) and that is the diagnostic tool that i use, is take the connector loose and look in the top of the sensor with it still installed. if the plug area is wet inside with oil, i would change the sensor. if it cranks you may be good to go, but we always change the pig tail when we change the sensor. ALSO, the truck does not have an edge on it does it? if so, remove it from the pcm and put the pcm back to stock and it will probably run.
