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.
