Latest update, I believe I have finally fixed this issue. The multiple codes concerning, the ECT, Cam position sensor, Cam solenoids and CKS all boiled down to a broken gasket on the X2 connector
for the ECM that was not allowing the connector to seat properly. Took it for a test drive and all was good. In summary, it is the little things that can easily be overlooked. I replaced my ECM which was having
com loss issues which solved this problem. And I replaced my EBCM as recommended by the Chevy dealer service dept. This solved all the ABS, Traction Control, and ESC warning lights. Now I can replace
the expansion valve and recharge so that my a/c will work again. I appreciate all the help from everyone!
