A code is a fault code and it indicates that something has gone wrong with your car's engine.
It can be caused by many different problems, including a faulty battery, a bad fuel pump, or even a cracked exhaust manifold.
You will need to diagnose the problem before you can fix it. The best way to do this is with an OBD scanner tool.
A scan tool will tell you what needs fixing and how much it will cost in order to fix that particular issue.
