18 Manifold P2005 Code (Help)

[Umang]

Has anyone seemed to figure out what the P2005 code is with the 18 gt manifold? I've heard from some people that it has to do with the wiring but I checked the wiring and it is exactly how to DIY shows. I've also heard something to do with voltage as well. I'm wondering if anyone has a clue as to what this code is.

PS: Any tuners on here do ghost cam tunes lol?

I have the same problem but haven't double checked my wiring. Who is tuning you?

VMP tuned mine a while ago. Idk it bothers me because I can't figure it out and move on to start doing other things with my car.

Are you having hesitation issues? Mine feels like it's misfiring some under light throttle generally right at 2k rpms, but probably 1800-2600 rpm in general. I never have it happen with heavy throttle or past those rpms.

So they gave me 2 tunes, one with the code and one with the code deleted so I can go WOT. So i've been running on the tune with the code deleted since I can't figure out the code. I checked my wiring and everything and i just don't know. But yes when I have the tune with the code not deleted the car definitely hesitates under low rpms

So if you don't have the code anymore and the is no issues with the way it runs then what is your problem exactly?

Also the code is for bank 2 IMRC stuck open if I understand correctly.

I have the same code and i do have my blue connectors wired into one.

You didn't understand I am assuming. I am 2 tunes, one tune is with the code not deleted and the other has the code deleted so the check engine light won't turn on so I can still drive the car WOT.

I want to fix the one without the code deleted because every time I upload that tune the check engine light comes right on.

Are you sure it's not a tune related issue causing the light to come on? It may not be anything that you can control.

Hmm i'm not too sure because I mean I did check the wiring and everything went exactly with the DIY. But I saw other people were getting the code so I never thought it to be a tuning issue.

My tuner seems convinced it's the wiring, but I'm double checking tomorrow I'll repost with the results.

Okay awesome thanks man! :cheers:

Data log and make sure imrc is still active with the code turned off. As some people have said the imrc voltage for being closed and open is different than the stock manifold. So if it's just tuned out I'm might not be working. If it was that the voltage needed to be corrected and was in the second tune then it's fine and was adjusted in the tune.

I reworked all of my electrical wiring even though it appeared correct according to the guide on the DIY section and another electrical schematic that someone sent me. I'm not sure what could be causing my issue now other than something in the tune. I'm going to do a log and send it to Lund tomorrow and hopefully I'll find something out. However the particular tuner I have thinks it's an electrical issue.
