Okay, a little background maybe related. For some time I have had intermittantly had the "service stabilitrak" and "service traction control" lights come on which is accompanied by harsh shifting. Never have been able to find cause of that. Today those warnings also had a CE light come on. Same shifting but nothing else noticable while driving.
Anyway a trip to the Zone later I came up with the P0011 code, which indicates camshaft intake position system performance. Probable causes - open or short circuit, mechanical condintion with sensor, failed actuator solenoid, low oil level (oil level fine).
So where is the sensor located? Could that sensor be related to my other issues? Is there anyway to isolate if it is the sensor?

Truck 2007 NNBS 6.0L 4x4

THanks for any help

The p0011 is a problem with the camshaft actuator system. It has variable valve timing capability. Need to have it diagnosed. No it is not related to the stabilitrac lights. That is a different system, as it should have codes stored also since the light was on.

Through the magic of the interwebs I found where the sensor was located.

The CEL turned off this morning. Oddly enough since the CEL went off I have had no incidents of the stabilitrak light coming on. For about a week that was happening almost daily, once on the way to work and once on the way home. I'm beginning to think I have some electrical gremlins.

Well with both lights coming on again I broke down and made a Friday appointment at the stealership for diagnosis. Stay tuned..

Got a call from the service department. The cam position sensor was bad. They also said the oil pan gasket was leaking and both CV boots were bad. Didn't have good answer for the stabilitrak/ traction control lights, but I'll talk more about that when I go to pick it up. The best news is he is getting everything covered under the power train warranty
I think I found a new dealer.

Hi.
Escalade 6.2l 2007 year
I have same problem. (P0011 and T/C light)
Please, write part # of the cam position sensor.
And tell me, please, what are "CV boots", which were bad?
And, how oil pan gasket leaking influences error occurrence?
Sorry for my bad English. I am from Russia))))

I don't believe your 6.2L would have the same part number since it's a different engine. The CV boots are the "rubber" boots that cover the constant velocity joint upfront.

Thanks for the answer!
I have found part # of my cam position sensor: 12585545
I will try to change this sensor, and then we will see result.
One more question:
Before the lamp CE (P0011) was lighted, the message "Low oil level" was lit, but The oil level is full.
Whether it could affect occurrence of error P0011?

[Policeman]

Thanks GMT-Forum!!! Сode P0011 is defeated.
I installed the new cam position sensor part#12585545.
I also found that most Service Stabilitrak illuminates when the engine errors are illuminates.

Glad you got it fixed
