P1005 code

JD319 · Sep 27, 2023

Has anyone here had P1005 come up,

Manifold tunning valve harness open or shorted
Manifold tunning valve circuit poor electrical connection

has anyone ran into this. Other than take in to the dealer, can anyone point me in the right direction as where the loose connection might be?

My man! Very nice. Couples well with the clicking noise under the hood that I've read is probably coming from high pressure fuel

pump.

Did you replace this part yourself?

Thanks

I have not had this issue. Just doing some searching for the P1005 code for this thread. Figured if two people have had this same code it had to be out there somewhere.

I think I ran across the original pit 5636 over at gmtrucks, didn’t seem like in 18/19 they had a solution, just cleared the code. Eventually ran across updated pit5636b with hopefully your solution

Okay. Thanks for the update. Have a local mechanic setup to take a look, but not until Dec. 1st.
