So installed a Diablo 87 octane tune yesterday. Drove 290 miles without issue. Best MPG I’ve ever had. This morning going to work i get this code. Truck doesn’t feel any different. Is this something to worry about or is it just cause i messed with the ecm?

Personally, I'd clear the code & see if it comes back. I'm curious about your Diablo Tune. What engine & year is you truck and current miles. What was the gas mileage change?

2014 5.3 6spd with 120k on it. Recently had temp sensor replaced, fuel gauge, front hubs, and lower ball joints. Applied the 87 octane tune per instructions to get a log. Drive 290 miles yesterday with a calculated average of 18.5 and computer said 19.7.

Given that the 5.3L only requires 87, what was the need to apply a tune specific for 87? Was it modded somehow or tuned previously?

That’s the thing not modded have had it completely stock this entire time. I reapplied the tune with afm delete though cause the first time i applied it it didn’t delete afm. Which is the primary reason i got it was to avoid lifter failure.

Flashed back to stock, still threw the code so something is up. Going to see if I can't  get it diagnosed and fixed this weekend.

have you looked through info on the code with something like this? https://www.carparts.com/blog/p0011-code-a-camshaft-timing-over-advanced-bank-1/

 

There are different things that could cause it, including "circuit issues." Might want to take a look at where the various sensors that are part of the system are located and see if something is chaffed or similar. Could also be one of the sensors in the circuit it bad, too.

I’m thinking it’s just a faulty sensor or circuit issue. I’m going to take it in though.

What about locating a service manual that would give info on how to test some of those items yourself? The diag process at a dealer would likely be the larger part of the expense for you. If you're going the private mechanic route, you would likely be a little less costly overall.

Guess that’s a good point. I suppose it shows me how to do the test?

Electrical connection from ECM to cam pos sensor interuppted reset ECM and start out again so it all mates up.

It may. Maybe someone -with- a service manual could chime in to let you know what sort of additional diag or testing info might be available. I know that there are ways to test the Oil Pressure Switches, but I didn't dig around on the internet in an effort to try and find details for the one I was recently troubleshooting. There seemed to be a high likelihood it was at least partially responsible for the issue I was having on my wife's Acura AND it was comparatively cheap and easy to replace. I didn't bother trying to test and just swapped it with a new one from Honda.

I’ve cleared it three times now. Flashed back to stock, then back to the 87 octane tune. Still throws the code. Though strangely 5 hours of driving Sunday it didn’t throw any codes. 
 

I also think i had the MPG booster tune applied because the mileage was way better than expected. After i reapplied the 87 octane tune it was right where i expected it to be

      OCI, not when but why?

      By Chuck FB · Posted

      I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters.

      AWD conversion to Z71

      By teamjnz · Posted

      I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
