If no wires or vacuum lines were disconnected or broken upon assembly, you will have to scan the car for codes to see what's up.
Was the coolant topped off, a low coolant level can trigger a CEL

You can drive the car with a CEL on, just make sure it is not leaking coolant.
:2cents:

Make sure the CTS is connected properly.

most when messing this job up do not properly reconnect the air pump correctly...recheck the air pump hoses /vacuum lines/electrical
