the dreaded Stabilitrak and P0011 code

I have a 2007 GMC Sierra Denali with the 6.2l. It has about 190k miles on it. About the last 10k or so I have been dealing with the P0011 and the stabilitrak lights. I did several deep forum dives and have replaced the following. The position sensor, actuator and magnet....did not fix it. Then I dropped the oil pan and replaced the pickup o-ring....no luck. So then I decided to replace the magnet and actuator again (first time wasnt with OEM due to availability). After the last the oil pressure has been reading high (60-70) and the light stayed off....for awhile. Came back on today. Truck has NEVER driven poorly during all of this, but still throwing codes.

I have no idea where to go from here. It seems this is a fairly common problem but not a straightforward repair. 

Any ideas are welcomed.

Thank you!

why are you chasing op issues for something that has nothing to do with the engine?

I'm not really sure what you mean. The p0011 code is the camshaft position sensor code. A quick Google shows that it frequently results in the stabilitrak light coming on at the same time. The fixes recommended that I can find start with the sensor, magnet and actuator and then the oil pickup o-ring.

Possible it's the wiring in that harness that is the problem now, you've replaced everything else.

Again, when it gets weird suspect the wiring, grounds, etc. I don't know jack about the stabilitrac system; I haven't had any problem with mine; I sure don't understand why oil pressure would have any bearing (no pun intended here) with a traction issue. I just read a description of the system and it's about applying the anti lock brake system to wheels that are slipping, the stabilitrac system can also sense when the vehicle is out of control and can affect steering according to the article I read. How that impacts with engine oil pressure unless oil pressure is used to tell the computer the engine is actually running or or not but there are other sensors that can tell the computers that like the RPM and cam position sensors/systems; maybe the vehicle uses more than 1 sensor to determine engine status...

Honestly I have no idea how or why they would be related either. The code that pops up in the system is P0011 which is the camshaft position sensor. EVERY time this code trips, the stabilitrak light comes on. Who knows why, but it seems pretty common unfortunately. I will have to start looking into the wiring.

No fix yet. I am actually having a hard time finding the replacement wiring harness. I bought the one that was supposed to be for my truck but it is 3 pin and my truck has 5 pins. I also replaced a brake switch behind the brake pedal as I read that my be it...no avail. 

I'll continue to update if I find anything.

Did someone find a fix for this??.

I have the same problem.

So here's an update to this post. I have replaced everything I can think of and everything I've read online related to this code. I've replaced the sensor, actuator and magnet x2, the oil pickup ring, the oil pressure sensor, the brake pedal sensor, the fuel pump and the camshaft position sensor wiring harness as well as multiple oil changes. No luck, light still comes on. The truck has still never run poorly during all of this but the light continues to come on with the same codes.

What kind of oil are you running?

 

If I was in your shoes, I would sign up for the shop manual at AllDataDIY and following the troubleshooting guide for that code.  I would buy a Tech-2 as well if the simple diagnostics didn't work.  It would have paid for itself already in your case.

      OCI, not when but why?

      By KARNUT · Posted

      It seems fine because it pulls everything out of a hot engine. I’m not going to worry about a thimble full with 5K oil changes with synthetic oil. Every other oil change is at Honda they pull the plug. I watch them through the process. It turns out going to Honda what amounts to their normal oil change intervals.

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.
