Has anyone ever gotten a permanent error code? I have a P0306 that is permanent. Jscan won't clear, disconnecting battery won't clear.

It sounds to me like it is in the permanent file. If it has been repaired and has not gone away after multiple restarts and drives, you may need to disconnect the battery, zip tie both battery cables together to get rid of all low voltage interference for up to 2hrs and then reconnect the terminals to the battery and restart the engine.
