posting for a friend at workhe's getting a PO601 code. some sort of Internal PCM Fault. google says replace the PCM. what are the chances of this code coming right back after a new PCM? it drives completely normal and doesn't show any symptoms other than the light on the dash, but he needs to pass inspection eventually.any ideas?
