I had this happen to me on a Jeep Patriot. They use flappers in the intake plenum joined together with a rod to a servo motor. The motor may have failed but much more likely is carbon build up has jambed the flapper valves causing a CEL. If you are mechanically inclinced and can confirm that the problem is the valves are stuck you can remove the Intake Manifold and clean it.
