To start with a scan tool (even a generic scan tool will do)will be needed to retrieve codes stored in the computer of your car indicating where the fault lies. Chances are something was disconnected while the ignition was switched on, the computer saw an open circuit and set a fault code. Maybe just disconnect and reconnect the battery and see if the check engine light comes back on.There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online .
