No idea on that code. Try to get it to Auto Zone or something and have the code read. This is were you can desifer the code. Engine Code Index

Sounds like a computer problem. Might be a relay as well. If ithis is your problem look under the hood on the drivers side for the fuse bx. OEM usually puts an extra relay in there. Try switching them out and see if it cures your problem. If it does just replace the relay. They (for the most part) are the same.
