At one time, the CTS had a failure mode that would allow coolant to wick up the wiring harness, to the ECM, and cause the contacts to corrode, hence, no signal (on the ground) and the ECM gets pissy, giving the "permanent" code..... check the connector at the ecm, don't remember which one it was.... and see if that is the case. If nothing else, once you find out which wires are the ones you want, test for continuity, and see what ya get.
