2012 3.8 limp mode with multiple codes

[Fishinhard]

Hi all I really hope someone can help I’ve got a 2012 3.8 that’s stuck in limp mode. Here is the sequence of events that caused this. My daughter started the car and went to leave and it would barely move she turned it off and restarted and everything was fine. On her way home the car went into limp mode at freeway speed I ran the codes and it was showing an open circuit in the tps. I cleared the codes and it was fine for about 5 miles then limp mode again. I recently changed the motor and thought maybe I had a loose connection in the harness so I disconnected the ecm and made sure the connections were good however I forgot to disconnect the battery. After doing this stupid move I cleared the codes and it immediately went back into limp mode I’ve tried clearing the codes over and over and always same thing. I’m concerned I fried the ecm. The codes it was throwing were all for the tps so I changed out the throttle body still the same thing. Here are the codes any input is greatly appreciated.
