Have you checked the wiring in between the camshaft sensor and the computer to see if it has been comprimised? Let us know.

Are you able to plug a scan tool into the cars computer and see if you can get a data stream from the sensor? It might not be picking up a signal.

I don't think the alternator bearings going bad would cause the problem you describe.

I would somehow double check to see if the sensor is communicating with the computer effectively. Sometimes a position sensor (often wheel speed sensors for ABS) won't be positioned just right or close enough to pick up a signal.

Did you use a factory service manual for the procedure to test the circuits? Ford pcm units are extremely reliable, failures are not common. Of course following the steps for diagnosing the issue sometimes results in the determination that it is the pcm, not often though. Don't be spending needless $$$, take it to a reliable shop versed in diagnostics, if it happens to be the Ford dealer, so be it
