P0641 Plus a few other codes I just wanted to post this so people know. I couldnt find much info on this issue.
I have a 2005 CTS-V and I tried to start is up and it was running like ****. Reduce Power came up on the nav, it would die, no throttle response, and missing. I check the codes and it has a code for almost all the sensors under the hood along with a P0641 code. That code is for a voltage issue to your sensors. As I understand it he sensors are daisy chained together getting there 5v for the sensor next in line with it. Turns out my oil pressure sensor went bad and caused all those issues..... Just a FYI
