What does P0607 mean on a Ford F-250?

The P0607 code on a Ford F-250 indicates a problem with the Engine Control Module (ECM) or Powertrain Control Module (PCM). This code suggests that the internal performance of the ECM/PCM is out of specifications, often due to electrical issues, software corruption, or component failure. Common symptoms include poor engine performance, stalling, or issues with starting the vehicle. It typically requires diagnostic testing to determine the exact cause and may involve reprogramming or replacing the ECM/PCM.
