One of the best videos I’ve seen! Been looking for somebody to walk me through this problem for a while now too
Thanks
Well done video, always love how well you describe and detail how and why things are done!
Thanks for noticing! I am trying to be detailed and continually improve.
Thanks for the video. Mine just went out on my 2008 LMM at just over 335,000 miles.
You’re welcome
Thanks for the tutorial....same model of my truck, just watched this vid....and I will do as you said to do.....
You’re welcome! Thanks for watching.
Hey Whiplash, my husband has the same code on this exact vehicle. We have replaced the vane position sensor, the boost control solenoid and the wires for it. And still same code. Should I try the boost control valve?
@katherinebogue7072 have you checked to see if the vanes are stuck and won’t move? Sometimes that can be the issue.
@13:21 WTF KINDA ROOSTER WAS THAT!! 😂😂😂
A Silky rooster is the one that sounds a little different. The other rooster is a Rhode Island Red.
I just threw a P0048 boost control solenoid high circuit, feels like the wastegate is stuck open but I’m going to pull this tomorrow and see how it looks. Still getting 25mpg somehow
Yeah it might be stuck open or the solenoid simply has a high circuit voltage.
I need to definitely check into this. Mine is sluggish into boost sometimes but isn’t showing any codes yet.
Sometimes it is as simple as things getting gummed up.
I think this is what I needed to confirm that I need to paint my truck white.
Heck yeah! Paint it!
Nice job
Thanks!
Really good job
Thanks
Well done !
Thanks!
Did this solenoid hold up? or did it fail after a few months?
Still going strong with no issues.
I have this same code for my 2005 6.6 dually. I noticed the idle is a little funny. Line it will ise fine then idle weird and the whole truck would shake. Thought the truck already shakes I noticed a different type of shake.
Will this fix my problem too??
Yours sounds a little bit more injector related. Have you checked your injector balance rates yet?
I have the same truck and the same code. I have changed the vane position sensor, the boost solenoid, should I try the boost solenoid valve?
The vane position sensor is often times not the fix. The boost control solenoid that I replaced in the video did the truck for me.
It looks like you have boost air leaks you should get 15 PSI at least 25 if everything's perfect like new
It goes up over 25psi when getting on it really hard. I didn’t get on it that hard in the video. Thanks for the concern though.
I can’t get it with the egr cooler in the way
Hmmm, might have to remove the cooler then or use a swivel with a socket.
I'm getting the P2563 and P0046. Truck has no boost from a dead stop. You can mash it to the floor and it falls on it's face. Then it will very slowly take off. Also my exhaust doesn't change sounds when idling.
Have you changed your Boost Control Solenoid?
@@whiplashtv2022 I have only changed the vane positioning sensor so far.
@@Dmax04 I changed that as well before I changed the solenoid. It turned out that the solenoid was the issue.
@@whiplashtv2022 I've been wrenching on cars for 48 years and so far I haven't figured out the combination to get on the head of that bolt. I have an 04.5 LLY but something is a little different.
@@Dmax04 that line to the turbo might be in the way. It can be removed if it is in the way and then reinstalled at the end of the job.
How long did you leave it in the oil ?
Overnight
What’s the peak boost?
The most that I have seen is 32psi
What about p003a
The vanes of the turbo charger not being moved and controlled correctly by the turbo boost control solenoid could cause this code to pop up. Also the vane position sensor not correctly reading the vane position could cause it as well. The boost control solenoid and vane position sensor are not crazy expensive to replace and you can definitely do it yourself.
I have a 0045....🤔
And a 2229
Your issue could be caused by this or potentially the BAP/MAP sensor or your problem could be caused by both being bad.
