what is trouble code p0401 and how to fix it?

When trying to start it drains the battery.In fact I charged the battery and eventually it ran out of juice again.Normally when turning the ignition even if it doesn't start it sound strong while trying to crank up.But now it sound very weak when trying to crank up.

Put a quart of brake fluid in and it leaked out. Saw the hole. Car is in great shape otherwise. This just started. Car has been sitting and no one was driving it.
