Hello I have a 2006 HHR LT with a 2.2. Over the last couple days it has been going to limp mode then about 5-10 seconds later it says engine disengaged. After it shuts off, I have to let it sit for a minute or so then it will start right up and drive fine. It has happened 5 time now and everytime I pull the codes it comes up with a P0601. The car has just over 95,000 miles on it. i have tried searching but come up with no results on hear, only the diagnostic codes sticky comes up. Any help or input or how it is fixed would be greatly appcreciated.

Thanks Rick_rob
