i need some help ASAP! im having issues with my LNF. I left work last night and noticed my CEL was on. I didnt think much of it at first but then started to hear the turbo flutter. I got on the highway and noticed the flutter more and realized I was in limp mode and wasnt boosting over 5. I got home and checked the codes and this is what i have:

p0236 - turbocharger/supercharger boost sensor a circuit range/performance
p2262 - turbo/supercharger bypass valve - mechanical

performance mods are K&N intake, 3 bar maps, turboxs down pipe, Term2 tuned. Ive never had a problem until now and I'm leaving for Milwaukee in the morning en route to Denver...

i didnt pull the maps but the wiring looks fine and theyre in there tight. i have the kit from CED so no soldering....

 

I dont remember if i got your second code before but it sounds familiar, i would check your bpv

 

from what ive read those codes could be a lot of things from a boost leak, bad map or tmap sensors,o2 sensor,or a faulty bpv.

 

If you still have your vaccum tank, delete that ****. look up the mod.

 

Check the lower MAP sensor. What O-Ring are on the MAP sensors?

 

I had p2261 and that one is turbocharger bpv stuck closed was close tho lol.

I deleted my tank and that did nothing, its a waste of time imo

 

I know it can be a bunch of things..that's what I was afraid of! The MAPs came with the new/better o rings, I believe it's the black ones?

I just cleared the codes and let it run for about ten minutes and just took it out for about an hit and everything is fine. No flutter and full boost.

I suspect this is only a band aid and something is on its way out but if it can last until I get back next week I'll be happy.

 

I still have the tank, maybe I should look at that as well...

 

I doubt its the tank

 

Oh trust me, it fixes LOTs of problems and the car runs MUCH better.

 

No it doesnt

 

No it doesn't

 

Okay then. Sure magically didn't ******* fix my car when a code kept on coming up for "Stuck bypass valve" and exploded a ******* intercooler and poped my chargepipe off. I did the vaccumm tank delete and magically at the same time my bypass valve decided to ******* work, oh yes ******* logic. ******* idiots.

 

Lol maybe the check valve in the vacuum tank failed. Otherwise no the vacuum tank didn't magically fix anything.

 

I had that code go a Forge no issue since. Unless u count have to relube the Forge at the drag strip that moble 1 can't hang with drag runs and 110° out side lol

 

well, drove down to Milwaukee today (3.5hrs) and had zero issues. No issues whatsoever since I cleared the code....

 

It was random for me, happend mabe 1 time a week till I got my forge I would just shut the car off two or three times and the code would go away car would boost fine.

 

deleting the tank when it's functioning fine is a waste of time you ******* moron. I'm ******* sick of you spewing bullshit about things you can only hope to comprehend. why did you have to get another lnf after you wrecked the first one

 

The vaccum tank is a bunch of bullshit and should of never been put in.

 

Exactly my point but im stupid according to him. So sad some people actually listened oh well

 

You don't even know what you're talking about or the function how can you determine if it's bullshit? You do not have an automotive engineering degree in turbocharging systems management.

 

Haha i told him the same thing

 

I think I'm have the same issue. My car throws P0236, P2261 I need to lube the forge when I get some time see if that fixes it.

 

The p2261 for sure is your bpv stuck i posted about it a few post up. But for sure lube it and it should atleast fix that code

 

Every time after about 2 or 3 start ups after u lube it. I have to lube mine like 5 times every summer.
