I came across this in my search. The part you're speaking about is actually called the clutch position switch. I just finished doing my best impression of a contortionist and taking my CPS out because my cruise control isn't working. Fun, fun.
I didn't have any CEL's but I plugged in my OBD II reader this morning just to see. Sure enough there was a code for the CPS. I cleared it and now CC is working just fine. Of course, disengaging the clutch doesn't cancel the CC, and the car will start without disengaging the clutch, but It'll fix that when I get the new CPS installed (special order).
So scanned it. no codes, This weekend ill try jumping out the sensor to see if anything changes. Anyone know i f there are any wires or connectors near the bank 2 cat that may have been messed up when the dealer replaced the cat? I took a quick peak yesterday and didnt really notice anything a muck.
ok for future reference for anyone searching, my clutch position switch springs were pretty jacked. I ordered a new one from ac delco off of amazon for 26 bucks shipped. AC delco part number is D2230C. The part number I used to find that was the number on my original part which is 11516184. We will see if this is the culprit
