Hello and welcome to JustAnswer!These codes are four the 1, 4, and 7 cylinders' MDS solenoid control circuits. If the solenoids and their jumper harness have been ruled out then the issue is either going to be a wiring problem between the solenoid harness and powertrain control module, or the module itself. There is little chance that the PCM is the issue.Do the codes set constantly? Has any actual testing been done?
