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.

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.

How many miles on her car?

[@michaelaboya4205]

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.

[@DallasAutoDiag]

Excellent job 👏

[@bryantnavarro1434]

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.

[@UncleSwell707]

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

[@DallasAutoDiag]

Big chance the turbo is going bad

[@UncleSwell707]

@@DallasAutoDiag damn. I did the disconnect battery trick today and now the lights dont even shut off, even after “system initializating, continue driving” message. How long can I keep driving before I really need to replace it? It’s funny cause the car drives fine with no problems.

[@joshuacampbell5673]

Same man, it's on hotter days for me in MD. I mean like 85°F plus. Did you see the play on the wastegate at the end of the video? I'm thinking for many of us there is absolutely nothing wrong w the turbo, but rather the wastegate isn't seating properly which causes an air leak. While annoying I don't think this is a huge problem. But full disclaimer, I'm no mechanic, just "I think" statements 🤣

[@DallasAutoDiag]

@@joshuacampbell5673 you might not be wrong. I was thinking the same. I also found out after the video that I can adjust the rod moving the gate. I just haven't got a chance to do another one.

I am so sorry. I mentioned in the video that we have to look at numbers after part replacement but I completely forgot.

[@luisacosta3361]

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?

[@DallasAutoDiag]

Did he tried to adjust the arm first?

[@fault_less]

Bought 2019 1.5 turbo. Got P0299 and P003A. P003A caused by “wastegate actuator learning” (at least thats how the code is translated). Does this mean it should be calibrated, or there might be a chance the whole part needs to be changed?

[@DallasAutoDiag]

You can try to adjust the arm and see if that's gonna make a difference. You may also need a whole unit.

[@jaydawg7200]

Could a bad o2 sensor cause limp mode and underboost? I dont get the p0299 code but the boost tach reads little to no boost😢. Sometimes i can drive the car but it jerks and i have to ease on the accelerator. When/if it goes to limp mode, I disconnect the battery to reset everything and repeat the process 😢

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.

[@DallasAutoDiag]

Is that the total with diag? Or are just the clips $150?

Just parts and labor, diag was an extra $120. I took the hose off, checked for holes and retightened the clamps, it is fine. I feel like they're just trying to get me out the door.
