2018 Honda Accord P0299 Turbocharger Replacement 

I like your work, explanation and hands on approach in repairing this car. My sister in law has this same problem with the P0299 code popping up. I've checked for damaged hoses/ leaks. After clearing the code it and several miles later ,it comes back. It is nice too have a good scan tool for diagnosing I see. Thanks for video in case I have this same task.

Thanks for the video. I had the same problem with my Honda CRV 2018. My mechanic couldn't find the leak and suggested changing the entire turbo system. I inspected it myself and found that there was a crack in the Turbo Charger air pipe joint. I had it sealed, and i haven't seen the P0299 code ever since.

Thanks for the video. I just replaced my turbo in the driveway on Sunday. Only cost me 625 for the turbo brand new Honda when I took off the old turbo it had the exact same issue is that turbo or the waist gate was really loose. And the new one of course was not and I’ve installed it I’ve driven about 129 miles. No warnings. No leaks and a lot more power. Driving like the day I pulled it off the lot. Thanks again for the video. Have a great one. Oh by the way to 2018 Honda accord 1.5 L turbo sport model with 148,000 miles. I had no damages no accidents here just wore out.

Thanks You so much brother for sharing this I have some issue I live in Dallas I wanna come see you thanks

Thanks for your time. I wish you could show some after numbers( voltage/mm). I have seem different electric waste gates that can be adjusted depending on the slack. But not all of them. Nice job. This is David from los angeles califirnia.

I had the exact same situation and I replaced the Actuator for the turbo which was like $150... Installed it and reset the CEL and the problem was solved... Did not run rough so i figure I change just the Actuator and that was the culprit.

مبدع ما شاء الله

Good input, thanks for the video. Questions, what type of fuel he's putting in the car, has he been doing 10k maintenance for the GDI, and lastly what the mileage on 2018

Mine popped same code has all the power and I hear no noise but do get under boost erased code and comes back on after 30 miles or so 2018 accord Should I change actuator or just replace whole turbo for something better and not tell the wife lol.ive seen a performance one I’ve been wanting lol

The same code in my 2020 accord, the mechanic did a boost pressure test, it had a range of 102 and when accelerating, it dropped to 96 and recommended that I change the entire turbo. What do you think?

Nice, Thanks!

Do those engin burn cooler when turbo fail on them ? And wasn't it simple to know that the turbo failed because of very low power while driving it ?

How do you activate the bov like that?

I have the same code no loss of power and if cleared only returns on hot days nighttime or cooler day I have no issues

hey this is a great video thank you! which diagnostic tool are u using? I would like to buy one

Are u referring to the beeping noise on the actuator or the rattle noise from waste gate

Hey man, great video. I have a question: I’m having the same PO0299 code (along with all them lights coming on at once) on my 2019 Accord 1.5T with 131k but started around 126k. At first, I did the “disconnect battery, reconnect “ trick and it would clear codes but I noticed that the code would come back after different mileages. First time after 700 miles, code came back on. Second time after 1,000 miles, code comes back. 3rd time, stayed off for about 2,500 miles then comes back on. Then after 800 miles, then 500 (I’m using the car to drive Uber right now, hence the reason I put lots of miles quickly). Finally took it to the dealer and after lots of test, came back with the same PO0299 code for “Turbo Underboost Problem”. After leaving the dealer (last week), code cam back on after driving 500 miles. It’s still on now. I did notice the po code would come while driving and in hotter temperature (I’m in Florida and it’s been in the high 80s, low 90s every week. Should I start planning on changing that damn Turbo? Thanks for any insight

I don't know much about cars. I know the the turbo makes the spool noice. On my 2018 1.5, I no longer hear thst noise. But thw boost gauge by tach seems to work.

I have 136k miles on my car bought it brand new. Went to auto for check engine came this popped up. Do I have to replace the turbo. Not mention I had my bumper replaced two weeks prior.

Very good

Do you need to re program the turbo after install?

Is thos problem linked to the accident. I have thw same accident and the same codes is showing up along with other electrical faults

can you please tell me how did u erase all the warnings and codes from 19:40 please ? thank you

hey guys so I did this exact job, and after doing this job the new turbo had gone bad and given me turbo rattle, the turbine shaft had gone bad and had excessive play. coolant Temps were good, oil feed line is good. not sure the reason why this new turbo went bad so quickly after installation. just wanted to give some feedback incase anyone else ran into the same problem. cheers 🍻

Man i wish i could send my Hyundai Sonata to you! It has that blinking check engine light

So if the turbo was good all he needed was to clean the waste gate ? Or did he need to buy the new turbo charger ?

Hello there , mines 2018 also 1.5L sport mine has most of the lights turned on. I had changed the spark plugs, and had cleaned the injectors. Had some problems with low power like no power . Ok so what i hd done is clean the intake hose with mas senor cleaner and also cleaned the 02 sensor on top . And of course i disconnect the battery. That was las week on Sunday and it was working perfectly. And just now the lights came back on. 11/18/22 i have an appointment next week at the Honda dealership to do a diagnostic. What should i do bro ?

141k and i got this p0299 code.... brought to autozone and the information indicated to replace intercooler hose and retorque.... nothing about turbo? This just happened after putting gas... weird... drives fine but everything is shot on dashboard..... tried u plugging the battery for hours but codes still there? Any idea how i can clear and see if it comes up again?

Does a bad turbo waste gate cause the car not to turn on ?

I changed the turbo and P0299 is still popping up, smoke tested the whole system and no leaks. Activated the waste gate and bypass solenoid and they work. Everything looks got but still under boost hmmm.

Hey I just bought a 2018 Honda accord touring from a dealer and I am having a problem where every time I use cruise control or lane keep assistance the car throws this code and I took it to a dealer and they told me it needed a new turbo for 3k I work with mechanics and they are puzzled on why you would need a new turbo if the only thing causing stuff to pop up is the cruise control car doesn’t pop underboost code unless you use the cruise control

What are the torque specs for the oil inlet?

Ahh the infamous wastegate rattle is a pretty good indication of a possible turbo gone or going bad

What is the normal life expectancy for turbo ?

blinking engine light for me, dealer supposably changed fuel injectors. but a month later its worse, im assuming they didn’t change it at all? (engine light disappeared and started acting normal after loss of power and jerking) magically 10mins later after turning off and on its ok🤷🏽‍♀️

How did you remove 11:19 oxygen turbocharger laf sensor

After one month lights come on error code 0299 turbo wastgate solenoid also chang ??????

Pretty sure this is me right now. I've had several P0299 codes on hot days that I've reset and keep coming back but no noticeable loss of performance and still getting 40+ mpg on the computer. Just took it to the dealer and they said they noticed the hose clips for the air tube from the air box to the intake are loose and offered to replace the part for $150... Call me skeptical.

Update no I have an over boost code after fixing the ender boost and putting in a new turbo. It happened after driving 852 miles since I put the new turbo on any ideas.

Please how much cost total part and labor.

How much was the new turbocharger??

Hey man i have the same issue id like to take my car to your place i am fixing to order the part i just need the labor.

How many hours in total to remove and replace?

Where can I purchase a turbocharger?

Explain to me this. What goes through the manufacturers brain to allow the car to go nuts with any code pops up. The whole car freaks out over a underfoot code, no abs, no lka,even the tire pressure monitoring goes off. I live my accord but they dropped the ball on this

ARCHIVES, there is another similar ACCORD video for those searching, I tried to post the link but its GONE???

How many miles on it?

I just had to change the Turbo today on a 2020 CRV.. Wastegate issues..

Mine does the same noise on the electric waste gate actuator

My wife as the same car and my problem was the air box wasn't tight cause we're missing a clip in the front of the air box causing to leak air...just like this car...why put 2 type of clip to close the lid tight...makes no sense.😅

I'm in fort Worth I have the same problem

What is p2252 code

1.5T or 2.0T??

This happens my car honda dealership charges me 2800$

why fails? :(

Wait this car has a turbocharger?

I have sama issue ( engine light) now , 155000 miles 😭

the wastegate is what goes bad. sometimes you can get the wastage alone on some sites. requires welding. I have done on 2 fords and Audi.

Sorry I saw the mileage after the fact

1.5 is junk

Accord and CRV 1.5 T too much boost

What kind of software did you use?

I had a 2018 accord 1.5T with 150,000 miles-turbo went. Sure wish this video was out when my turbo went. Looks simple. My CVT input seal began to leak at 170,000. Got rid of it! Disappointed honda went to turbo, just creating more profits for the dealer
