That means the Engine Computer has detected a problem, set a diagnostic fault code, and turned the Check Engine light on to tell you. Many auto parts stores will read the codes for you for free but you have to understand those codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis.
