On my 2011 Chevy Cruze I have a P2076 "IMT" code. I've been told that this is an Intake manifold tuning valve sensor, problem. My mechanic found a rod apparently pulled out of a small plastic housing which is located on the intake manifold unit between the inline engine and the fire wall. He now thinks I will have to purchase and replace the entire intake manifold unit. He estimates the cost to be around $1200.00. I have had this engine check light on my care for about two weeks. It has not had any affect on the performance of the car. Is this a common problem and if so how can it be fixed.
