I had an engine code pop up that was for the "Intake Camshaft Position Actuator Solenoid Valve Control Circuit(P0010)." I just changed my oil yesterday but the mechanic said that wouldn't cause it. He said it was just one of two Circuits on top of the engine causing it and that all I would have to do is pop new ones in and it would go away. Anyone ever experience this and have any fixes? I drive a 2010 base model Cobalt.
