Don't see many DTC codes that come straight out and say "replace PCM". Here's some information that may help if looking for a "junk yard" PCM.

ForScan ODB2 scanner w ELM327 USB

If this were my car I would double check:
  • power(s) and ground
  • look for water damage
  • look for rodent activity
  • inspect the PCM printed circuit board for evidence of over heating or water intrusion.

P0606 - Powertrain Control Module Internal Communication error

P0606 indicates register readback (PCM internal Communications) error.

  • Damaged PCM
