I have maintenance required message and check engine light after head gasket replacement. Codes are Current $03, Pending $07, Permanent $0A. Battery was disconnected during repair but I'm guessing the Permanent Code survived. One SNAFU during the repair caused disconnection of the knock sensor wires from the clip but I soldered them back on.
