Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.

The code P2601 on your 2009 CTS is a known fault code and GM has released a service bulletin dealing with it and the proper repair for it which involves replacing a failed auxiliary pump and resistor due to overheated Mosfet resistor internal to pump. I have enclosed the bulletin in the link below for your review as I suspect this is the cause of the problem you are having. Have a look and post back if you have more questions and or need more help and we can work from there if need be.
