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.

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.

      They’re not the same wiz as 10-15 years ago.  QC has fallen pretty hard.  The XP line was never good though in the first place.    https://bobistheoilguy.com/forums/threads/wix-filter-rusted-through.386492/post-6991372   https://bobistheoilguy.com/forums/threads/i-ve-used-my-last-wix-filter.27299/   https://bobistheoilguy.com/forums/threads/looking-for-a-better-replacement-for-wix-51258.403977/   https://bobistheoilguy.com/forums/threads/convince-me-in-using-the-purolator-boss.401537/post-7420147   the forums are littered with posts and examples of not great wix filters the last couple years
