Ford F150 2004 Failure P0606

I have the fault code in my Ford P0606 design that is the PCM/ECU INTERNAL FAILURE-
The symptom is linked in cold I put it at temp. normal and handle it approx. 1 to 2 hrs and the failure begins as bad combustion marks me fails on PCM and etc.
I already replaced etc and continued marking the same.
I already reset the kam and the same rename 10mnt and remained the same.
Will you have to change the PCM or reflash?
Someone can help me, I would appreciate them.

The failure I see is that you heat the processor. Take the car switchboard, inside there is a square chip or is under an aluminum emfraiator or above a plastic base.

You must have dried the pasta, you can go to a PC sales store and ask for paste for processors. That paste should not touch the connectors is just to throw it over.

If you want before trying anything, use the vehicle with the open switchboard, to see if it is a heating problem as indicated by the code.

You already comment if you did well.
