    THANK YOU! THANK YOU! THANK YOU! I have a 2013 F150 Ecoboost and at 50k it had an underboost code. I'm an EE so mechanical like this eludes me and I took it to the dealer. $6,500 later new turbos. Now at 100k, underboost code again. Your video is awesome and thank you for this, 25 bucks on amazon and it is now working great. Big hole in the gasket. It was easier for me to use a 1/4" ratchet after removing the hose.

    Thanks for this video. I have a 2013 F150 3.5L Ecoboost and I was getting the P0299 code but it would only do it when I towed my boat. I could clear the code and during regular driving it wouldn't come on. Only when I towed my boat would I get this issue. After watching this video my son in law replaced the part for me. I then towed my boat from Lake Charles, LA where he and my daughter live back home to Austin, TX and it never came back on. If you're getting this code when towing I'd highly recommend changing this part. Also I was able to get the part at O'Reilly's for $60 rather than pay the Ford Dealer who wanted $112 for it. Also the part is now AA5Z-9U465-A.

    Hello! I just had the code hit on my 2013 F150. I grabbed the Amazon part to put in. As I was taking the old part off the bolt near the wheel broke (it has more corrosion). I am going to try to rotate the part and use the other holes! Wish me luck. I just need to find another lag type bolt for it. I hope that is why Ford put the two mounting holes there. In hindsight i would have sprayed some WD40 or PB Blaster on it. Also, my old part had not obvious tear so we will see what happens. Thanks for the great video!

    I installed the Amazon blow off valve and it reduced smoke a great deal. I think there is residue in the converter and exhaust which hopefully will burn off eventually. I didn't find a diaphragm tear, but if you hold to your and listen to the sound, I think I heard a difference in while pushing the plunger. We'll see.
    Well, replacement didn't help, as the ultimate problem was a blown turbo. I replaced the turbo and after the excess oil finally burned out of my exhaust it runs OK now.

    I have a 2018 accord 1.5 and I got the emission system problem light came on. I went to autozone to use the OBD reader and it gave me code P0299 turbocharger under boost. And recommended most likely solution: reconnect and or re-torque intercooler hose.
    My local Honda dealership told me I needed to replace the turbo charger. Now watching your video, could the fix be something else than the replacement of the turbo? Any feed is greatly appreciated

    • @williamtunnell
      @williamtunnell  Год назад

      Absolutely. Underboost indicates that pressure built by the turbo is being lost somewhere - or, of course, the turbo charger isn’t creating enough boost on its own. So sure, the turbo could be the problem, but there are plenty of other places that you can be losing the pressure that could be fixed much cheaper if not for free. Check all places where air could be leaking after the turbo. For that matter, check areas before the turbo as well. I’ve just learned to seek out the cheapest and easiest and simplest possibilities first before replacing a costly part. Good luck! Let us know what you find out.

    2016 expedition, 118k. kinda sluggish off the line, but has good power at higher rpms. No codes. I first removed the connector from the boost valve and found it to be full of oil. My suspicions is a tear or leak in the diaphragm which is not visible. Any Thoughts?

    • @williamtunnell
      @williamtunnell  Год назад

      Hmm, well this diaphragm is in a blowoff valve which lets off boost pressure when necessary. So the code throws when it leaks and won’t allow normal pressure to build up. The code, then, is an “Underboost”. The turbos are fine, but the computer thinks it’s not getting enough boost - because it’s not. With your issue arising at low rpm and no code, I’m not sure this is your fix. But for $35, it’s not an expensive experiment. My code would come in under load. Hard acceleration or towing. I certainly believe you should not be finding oil all over that valve, though. But I’m honestly not certified in anything!

  • @terrycuzzort3181

    When your truck would throw the fault would it ever go into limp or de-rate mode? My torque converter is slipping and when I pull anything regardless how heavy or light when I hit any incline service light comes on and trucks goes into limited de-rate. I can shut the truck off then back on and de-rate goes away but the engine light stays on and it gives the same fault code P0299. Any input would be grateful.

One was the part featured in this video, and the other was that I had to replace my throttlebody. No idea why, and very strange that both of these problems were happening at the same time. Nevertheless, the throttlebody worked and I’ve never had limp mode again.

    Your probably having an issue due to the way you plugged it in. That rubber seal and blue plastic retainer you put in the post doesn't belong in the party first. It goes on the connector then the seal goes on the outer part of the connector. Then plug it in. If not your seal is not gonna fit in there right that's why it looks so crunched up in the plug.

And the code is p0299. Is this the same thing I need to do to my rig or is it two different things. Nex, is there two of these on the truck since it’s twin turbo.

      Yes, and you’ll want to read this. First, while installing it, it pulled apart; something I can’t get the OEM part to do. However, it popped right back together and seemed to function fine. I guess it’s just made differently but it troubled me when it came apart in my hands! I just reassembled it and installed it. Seemed fine. I got the code almost immediately - same day I installed it, and under no load whatsoever; literally just cranked it up and didn’t move. I cleared it and have never gotten it again like that. This weekend, however, I did get it again and it’s doing the same as the OEM part - check engine light comes on under a heavy load (pulling my 10,000 lb. camper) and during take off. It does not send the code pulling up to 70 mph, but only if I take off heavy - and only while towing. To be honest, I’m pretty satisfied with leaving it like it is - and deleting the code. It doesn’t effect the performance that I can tell. In short, after running it for a while now, I honestly don’t believe the Amazon part is any worse than the OEM part. Sorry for the length - but that’s the rest of the story.

      It’s probably not something you should attempt in a driveway but possible with much patience. Definitely want to replace the coolant and oil lines when installing new turbos .

      @teenice894 I haven’t diagnosed anything further. It hasn’t thrown that code in a while now. I believe I simply have an air leak somewhere - probably a faulty connection. It only does it under load and whole accelerating. I think the turbos build enough boost to just push the air out somewhere else and cause the boost loss. It’s one of those things that isn’t bothering me, and you don’t notice any power loss so I haven’t worried with it any further. If it gets worse and more common, I’ll have to track it down.
