So the title says it all. It lists this twice, 2nd one is pending. At one time I was pulling 7 codes all related to this. My light will be on for a few days and then go off. All of the sudden I notice the car driving sluggishly, and a little later the light returns. I took the car in a couple months back for this under warranty and they said they just reprogrammed the PCM. I was doubtful at the time that this would correct the issue. It did take longer than before but the light started coming back. What should I tell them they shoud do this time, replace the sensor? could it indicate another problem? Is it bad to be driving around with this on for so long? Could they come back with some B/S saying it is because of my Corsa exhaust or some other aftermarket change? As you can tell I don't know too much about how a car actually works. Thanks for any input!
This cropped-up a couple of times for me. The dealership simply cleaned & greased the connector to the offending CPS and it went away.
Thing was though, they would ONLY do the one that caused the code to throw (I guess they wanted the repeat business.... ) SO, I did them all the next time it happened (wasn't sure what was, and was not, done) and haven't see a return for over a year now :D

My recent similar experience... http://www.cadillacforums.com/forums/cadillac-sts-forum-2005-through-2010/206063-bad-day-codes.html
I had the same problem two weeks ago on my 08 3.6DI. The dealer fixed it under warranty as I had 48,600 miles on it. http://www.gmc.com/100kwarranty/coverage.jsp
There is a tech bulletin on this problem and it involves a serious tear down of the engine to fix it. Here's the bulletin.
Note that the bulletin covers a LOT of vehicles so if you have one of the others also you just might tell the Dealer about it if they claim they don't know about it, which they just might do. This is a 5 to 6 hour job and requires a special tool, so you might ask them if they have the tool and the parts (thrust washers) BEFORE they tear down the engine. My dealer told me that to continue to drive the car probably would have little or no effect on the engine for some time so you can probably wait on parts for awhile but your 'check engine' light will stay on and if something more serious happens, so solly bout that. Here's some more info on the problem and what others are doing about it.
