- How to fix P0299 Code: Turbo / Supercharger Underboost Condition
The boost is the amount of positive pressure that is being created by the turbocharger.
When the pressure is low, an underboost condition will exist, which the computer (ECM/PCM) will receive through sensors and send out a P0299 code.
The computer calculates the parameters with data from sensors such as the mass airflow sensor, ambient air temperature, and manifold absolute pressure sensor
The computer will consider variations but there is a threshold of pressure needed or the computer will send out a P0299 code.
Possible Causes of a P0299 Code
Intake Air Restriction (Dirty Air Filter)
Bad Waste Gate
Bad Hose Connections
Air intake leak
Faulty sensor (BARO/MAP/Boost Pressure Sensor)
Faulty intercooler

Thank you for an excellent presentation, well made and helped lots - thank you 😊
Well

Hello Sir,
Thanks for the video. How long can I ride with that code before getting it repaired? All the lights in my dash are on. It's running fine. I can't understand how I got a brake job 3 weeks ago then 2 weeks later all the lights in the dash of my 2022 Honda Accord are on. I have 162k miles on it and have taken good care. Now this trouble. They're telling me it's 2400 to repair it at the dealer. In face all the codes state "see dealer "
I just had this code after fixing my car for timing chain cover leak. The code came together with P227900 Intake Air System Leak. I can hear the air leaking (loud hissing noise) when paddling above 2.4k rpm. This is not common. Need to further checking with the mechanic tomorrow. The mechanic suspect have issue with the N75 air hose vent. Need to further diagnose. I am driving 2013 Jetta. Thanks for your tutorial.
I have a 2005 T1N 2500 van.. I got this P0299 code. I couldn’t find a leak and also I hear the leak only after I drive for an hour or 2 and then all of a sudden I hear it leak and my turbo don’t kick in. I have to turn on and off my engine and then it works fine for 30 to 40 miles and same thing repeats.. any idea what might be the issue?
I have a 2017 Buick Encore. I got a P0299 code last September. I tried all the checks recommended by various mechanics. I came to the conclusion it has a bad turbo - at less than 40,000 miles. I recently received a letter from GM that if the vehicle has a bad turbo before 10 years or 120,000 miles, GM will replace it. It's been at the dealer 3 weeks now. They have determined it's a bad turbo. They're really dragging their feet, but I hope they will replace it. Obviously, GM has lost a lawsuit.
Update: I just got my car back, after 5 weeks at the dealership. They replaced the turbo and related parts. Cost: $0.00
Iv got a 2019 Chevy cruise with the p0299 underboost how can I find what to fix with out buying a new turbo .it only reduces power when taking off from stop .an runs fine Untill I stop again it acts like it is sluggish also
Tenho uma Pajero Dakar diesel 2013 - 3.2 - anulei a EGR começou a aparecer esse erro P0299, ativei à EGR e o erro não apareceu mais
I had this error on my Jetta sw, I replaced the boost pressure valve, but I’m still getting the same code. what should be the next thing to look into?
I had the same problem before .Check the bottom hose that is going to the intercooler that's usually gets sucked or loose
Hey, I have this code in combination with a P0101 code..what action should I take ? Is this a sensor problem when combined with the P0101
They likely are separate issues, but I would clean the MAF sensor, clear the codes, and see if they come back.
Very helpful, thank you. Is it ok to drive with this code if your vehicle is running well?
Did you ever get an answer bc mine is doing this an I gotta work .. which is far.. 30 miles one way
@@nae1300I’ve been running mine for about 3 months and I do good delivery, I just clear the code but I’m hoping to fix it this week
Man me too n I sleep in this mfer 😢
@@-2k5 I had to change the turbo out
@Beast-rz9cd
What was the issue specifically? Bad blades? Scratch up housing? Hard to believe the entire turbo needs to be replaced unless you're getting one pulled over your eyes by the mechanic
Any estimate on how much it will cost to fix it?
2015 f150 around 2k to fix it.
2014 kia sportage underboost same code . Sometimes turbo is functioning sometimes not
Bro I get that problem too on my Chevy trax 2018 1.4 lit 4cylinder, it will come on for a little bit then turn off for a while, so I assumed it might be sensor related or something with the waste gate
