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.

A scan tool will tell you what needs fixing and how much it will cost in order to fix that particular issue.
