2018 6.2L, Post DOD Delete in Reduced Engine Power Mode

[Joshua Heaton]

I finished the DOD delete on my 2018 Silverado 6.2L after the lifter collapsed and bent a rod. Sent to a shop to get professional tuning. Once completed we cranked it up and it goes into reduced power mode as soon as the key is turned on. It throws a crankshaft and camshaft position code. Both sensors replaced and connections look good but still have same thing. When you try to delete the codes the engine shuts off. Tried to do a relearn and the engine shuts off. Tech said he has been through the whole wiring harness and didn't see any issues. Tried new ECM and same problem. Any ideas?

Without seeing the tune file they wrote to the truck, I can't really say.

 

I use HP Tuners for tuning these trucks. Also did you keep VVT or remove all that too?

@GMCustomerService can you kindly explain how this post provides any kind of resolution so others can know how to fix their problem? The point of this forum is to provide help with solutions to fix problems. I have yet to see any of your posts do that

I think it’s funny how this, I’m assuming bot, is trying to get the OP to take his afm deleted truck to a dealer. I have a feeling they wouldn’t even try to address his issue due to the mods it’s had done to it.
