A short in the one of the circuits can do it, however, finding it can sometimes be difficult. For example, some Nissan VQ35DE engines had the problem of the IACV/AAC valve shorting and damaging the circuit board of the ECU. If the board is again damaged, I would send it back to the company that repaired it and have them identify which circuits or pins are, or, may be related to the part of the ECU circuit board that is damaged. At least then you would have a general area of where to check for the problem on the vehicle.
