If you don?t have a FSM I can snap a pic of the code 55 as well to help.

Yes it did it after being hot shut down for a bit and then restarted I?ll definitely check knock sensor

That?s what mine has been doing for the knock sensor code. It says in the manual it runs a test and if it fails it sets the light. I got a sensor, just gotta get under it and see if it?s the connector, loose, or just replace it.
