OBD2 Codes U0401, P0573, P0504, P160A After ECU Swap with Mismatched VIN - Car Won't Start and Runs Poorly

Model: ECU Swap Fault Code: P0504 Posted: 2022-12-18 18:07

After swapping my original ECU with a used one purchased online that has a different VIN number than my vehicle, I've encountered several OBD2 diagnostic codes: U0401, P0573, P0504, and P160A. The locksmith programmed the key to the car, which allowed it to start and run, but persistent error codes are now appearing along with noticeable performance issues. I'm seeking advice on how to resolve these codes and whether the ECU swap with a mismatched VIN is causing the problems.
