2011 Chevy 1500 LT crew - 144k miles
So, after countless hours of searching, I’ve decided to post here in desperate need of help.
My truck is currently in the shop, and on its 3rd mechanic trying to diagnose/fix the issue.
Originally I was getting an oil pressure sensor unit code months ago, and about a month of driving later, and I finally lost my oil pressure gauge (dropped to zero) but the truck was perfectly fine.
No loss of oil, etc.
So I brought it in to get it fixed and change the oil - they put an OEM part in and changed the screen.
Reset everything and I picked it up, a few moments later my check engine light returned.
Scanned it when I got home, same error code - active.
Checked for oil leaks, etc - nothing.
Returned a month later for them to fix it, they put in another OEM part and new screen…drive it 3 miles down the road, and it trips again.
They’ve checked the valve cover gasket and checked the PCM, everything seems fine.
The truck is not burning oil either.
I’ll add that my oil pressure gauge on my dash works fine now since they swapped sensors too.
Everyone is stumped on what to do, and I’m about to potentially go down the rabbit hole of ‘throwing parts at it’. Starting with the PCM and then the valve cover gasket, and many thousands of bucks potentially.
Does anyone have the slightest idea what’s going on? The PCM is throwing no other codes either, he has graphed and checked it.
Is it possible for the PCM to be corrupt without it giving errors, etc?
The tech is a 30 year vet, and a family friend - so by no means is he stupid. But this has stumped two other techs with equal experience too.
Now my truck is past inspection, and with my Check Engine light on, it’ll never pass. Plus I’m still half way on my loan, so just selling it isn’t an option.

Snapchat-2110446941_1_1.mp4 I got Silverado 2018 Ls single cab with BF Ko2 tires factory size, gonna lift the front 2.5 inches , so , i intend on putting method wheels, but confused with the size of it.
What do u recommend?
Is the tires size ok with the 2.5inch lift?
Tire size 265/70R17
By the way the front lift is Motofab.
Hope i can get answers.
I have an autocal from Black Bear Performance for a 2015 Silverado. I’m honestly not sure which vehicles it will fit. It has not been hooked to a vehicle. I bought it back in 2016 and sold the truck in December 2020 and never even tuned my truck. I’ve got a 2021 Duramax LM2 now so I can’t use it. Asking $350
I also have a full set of Grey Carhartt seat covers for crew cab that cover head rests, all arm rests, cup holders, consoles etc. it’s front and back and for the flip up console. They are waterproof and washable. I’m thinking I paid $500-550 back in 2016. Asking $250
I also have full from and rear Black Weathertech floor mats that go all the way across front and back. These will be harder to ship so if you’re in central Missouri/KC area it would be easier than trying to ship. Asking $100
All prices are shipped! I’ll have to see about the floor mats though. I can get pics if needed but my truck is sold so they will not be installed pics.
So I have searched Google a ton, with no luck. I am curious: has anyone tried to tune their truck in such a way to get the AFM to engage more often? There's tons of solutions for a full AFM delete. I wanna know if it's possible to go the opposite way; and increase the tolerances on whatever parameters the ECU monitors (engine loading, throttle position, etc...) To trigger V4 mode? I don't have a great need to actually do this....I'm more curious than anything....
