P0605 code

I have a 2003 4.0l with AT that is displaying a p0605 internal memory code. I though that it indicated the PCM was defective so I picked up a used one at a autosalvage yard with the same part number and id#. code remains still after resetting. When I hold down the trip reset and cycle my key 3x I get a 04-05 code. I believe thats a EGR voltage code. Any ideas/Help.

First Welcome to the forum. You can find that code under generic codes at the link below. They also affer help in determining what the specific problem is.

Does yours have a separate transmission control module by the washer tank? If so, that might the culprit.
