The Check Engine Light indicates the vehicle's computer has detected a failure in one or more components of the emission control system. You will need to retrieve the codes stored in the computer to troubleshoot the problem. More info here; http://repairpal.com/check-engine-light

Probably a CO2 Sensor!
