Ivan, my son's RDX had the same issue. What caused the Turbocharger boost control valve to stick was a coolant leak between the exhaust manifold and head. The engine coolant was running down to the control valve post and burning off causing it not to move. I removed the turbo and cleaned off the burnt on coolant, the valve freed up. Some high temperature anti seize lubrication was applied to the area along with all new gaskets and seals. The vehicle has been running fine for the last 2 years since the repair.
I had a local guy who does work on the side change it for me. I bought an autozone turbo. The dealer will insist on oem. There is risk the non oem won’t last as long as oem. But u could do 3 swaps of non oem for the price of OEM. My guy said it was a huge pain & he had to drop the subframe to get it out and back in again. It’s kinda sloppy of Honda not to consider some level of repairability for these turbos. Luckily the new RDXs have the turbos on the front side where they are easily accessible. Good work ivan trying to save the customer from that 9k bill.
The actuator within the turbo is probably carboned up, that is why it is not moving. On my Ram 4500 with the Cummins 6.7 I had been fighting a P2262 code which everyone said is a "Turbo Death Code". With these turbos you have an Exaust Brake. Started using Hot Shot cleaner & diesel additive to increase cetane and have cleaner burn. Ran the snot out of the truck (75 mph max is all these C&C trucks can go) in the NH mountains for a few hours. Drove it hard with loads in the dump bed. Eventually it cleaned it out and no more code. Do these RDX's need premium fuel? If so, was the customer using Premium fuel? if not he may want to try it and do a bunch of hard runs for a few weeks to see if that frees up things.
Here in Sweden you can flash stage 2 firmware in the ecu and it will ignore the boost. And advance the timing a tad. Also run the injectors abit more aggressive. What is key is that this firmware does not give any fault codes or limits performance for any reason what so ever. I would think in USA that's not allowed to do. But cars here before 2003 are fairly safe to do that on. And they can be inspected and passed even with engine mil light shining. However... They have to test emissions at the exhaust and pass the physical test. So if legal that could be a route to go. BTW... Following your tactics for trouble shooting I found a broken collapsed vacume line from scandata. I think your absolutely brilliant Ivan. And I would love go meet a person like you here in Sweden. Would leave my car without even the slightest worry.
We did one a year or so ago it was the turbo. It was through an aftermarket warranty company. They wouldn’t use the genuine Honda part. They sent us an aftermarket unit. I don’t remember from where and you are right studs broke we needed I can’t remember a manifold or something else was cracked It was just a disaster but in the end we got it done.
Want simplicity drive an older mercedes 240D w/manual xmission. No turbo, no ignition, and almost no power. I bought mine with less than 100k mi. Now has 361k. 😊
Map reads intake manifold pressure. Atmospheric pressure included. It should read more than 14.2 w even .22 psi of boost. I suspect a boost leak and possibly dirty map sensors. And guaranteed the variable vains in the turbo are stuck. Run at least a cpl processes of cataclean in the fuel tank.
Thank you Ivan. You had it around the 8 and 9 minute marks, boost pressure sensor. FF data boost pressure reading 0.2 psi when code set. This is an absolute pressure sensor. The 0.2 psi is inaccurate.
the same occours on vw tdi turbos and is caused by carbon build up that stops the vanes from moving if you remove the turbo and strip it down and clean it out that will get it back to spinning up quicker at lower rpm but i have found a fair percentage unfixable due to the acctuator rod being worn from rust where it passes through the body removing it 1st for inspection is the only way you are going to figure out if it can be repaired or has to be replaced
Maybe there is an aftermarket tuner that can disable the turbo performance check from the PCM? I know HP Tuners can do just about everything, unfortunately they don't support Honda / Acura vehicles. Thanks for the case study Ivan. 👍
Might I observe that the "theory of operation" is not complete. You observe the car is "picky" meaning there's a missing ingredient of discussion. I get the challenges of design and the meeting of milestones for delivery and I get that LAST on delivery schedule is flow charts and theory of operation but as technology increases exponentially so do documentation requirements. Technicians stand no chance if (s)he can't learn how the system operates.
People remember to buy something simple. Point a to b until you are wealthly. Look poor but be wealthy. My 4cyl NA honda accord is a blessing. Gets me to work making over 200k and protects my family!
That was pretty interesting. 7 hours for the turbo - more like 12 in the real world where things rust. Plus the ridiculous price of an oem turbo. In summary - F that.
I think it's absolutely criminal that just having the light on can fail emissions. A turbo spooling a bit slow isn't creating any pollution. Something like a flaky alternator field circuit isn't creating any pollution.
Ivan these are great cars....however if its got over 100k you need to replace the actuator assembly or at least the eye bolt that you adjusted...the eye bolt is available on ebay less than 50bucks...the round eye becomes wore out throwing of the clearances and changing the clearances while in operation....
Awesome diagnostics there Ivan why do we have to be so darn technical but if you can afford an Acura you can afford some serious parts replacements good job there boy
How unfortunate, Ivan! To hit a roadblock, after all that effort, particularly when it could potentially be solved with no parts required! If only there was access to the turbo... So annoying!
Just curious, have you ever been pulled over testing a customers vehicle or looking at scan tool data? With my luck - I wouldn't be able to do that lol
you can't even get a long steel rod onto the lever? how about applying some higher pressure air to the actuator? It's made to withstand 30psi, it should be fine with at least 60psi. even if it blows something, it's already broken, so no harm done? plug off that port on the charge pipe so it's not losing boost via the blown diaphragm, and send it on.
Replace the whole engine , I don’t know why states up north people get so messed up with cars , down here in the south there is always a way to fix cars !
It varies in Pa. from county to county, as rediculous as that is. My county has no emissions tests, except for visual, and a neighboring county has emissions testing for inspection. Go figure. Pretty much normal for anything the government has their money grubbing fingers in. And many states have no yearly inspections. Go figure again! 😅😅
In PA it varies by county. Some counties have emission inspection, some don't. The ones that don't just check the gas cap for leaks, plus some sort of visual inspection of emission stuff - make sure it's there.
7k for a new turbo?!?! You can get a whole new engine in an old Chevy for less than that. Ask me how I know 😂😢 Hellish diag to take all that time, effort, and frustration just to discover the worst. Ugh.
I agree if you don’t have any knowledge of turbocharging, the components that make up the system and have to pay a shop or someone else to diagnose, maintain, and fix your vehicles. Unless you are leasing or buying new vehicles and trading them in before their warranty’s are expired, then that’s probably good advice. However, many people can and do work on their own cars/trucks and prefer to own performance vehicles. As turbocharging always offers the highest power for dollar return available. Having owned turbocharged performance vehicles for the last 20yrs when you understand the system and the components that make it up diagnosing issues related to the turbocharging system are actually pretty easy. Having the ability to datalog engine parameters and sensor data is really helpful also. Maintenance is definitely key though as in over 20yrs now I’ve not had a single turbocharger related issue in any of the turbocharged cars I’ve owned.
This one genuinely makes me angry. Like, no kidding angry. It's a perfectly running and driving vehicle reduced to trash entirely. If he lived in a zero inspection state he'd be fine. Rrrrrgh this makes me so angry.
It depends on the application. My 1983 Mercedes 300D-T had the original engine, turbo, transmission, and differential when I sold it at 450k on the odometer and the guy who bought it from me kept running it until it rusted down to nothing. Back in the day, simple turbocharged diesels were bulletproof. Late model turbo gas cars are a completely different story, and ever-increasing intervals for oil changes don't help.
should you be interested... there's laser treatment for your forehead wrinkles. The laser action results in collagen build up which erases wrinkles. I did it... not very difficult... not too expensive.... a bit of gross forehead during short recovery.. but I'D DO IT AGAIN. You do have to LEARN to not frown.

Like I said, turbos, EV’s , hybrids, might be the greatest thing ever to some , but not for me. Simplicity rules in my book. Nice work Ivan. 👍👍😅
Agreed! I had a Jeep Renegade fail to enter 4WD because of a defective thermostat.
Want simplicity drive an older mercedes 240D w/manual xmission. No turbo, no ignition, and almost no power. I bought mine with less than 100k mi. Now has 361k. 😊

Send the turbo to Area Diesel Service.. I would be willing to bet the price is a tad less than 7k.. worth a shot. They do all sorts of turbos.
Turbo repairs: "triple boat payment" as the Car Talk guys used to say.

This reaffirms my belief to never own anything with a turbo...are you listening Toyota?
People remember to buy something simple. Point a to b until you are wealthly. Look poor but be wealthy. My 4cyl NA honda accord is a blessing. Gets me to work making over 200k and protects my family!
Yup. 2006 Matrix with over 226,000 miles and it still runs perfect.
That was pretty interesting.
7 hours for the turbo - more like 12 in the real world where things rust. Plus the ridiculous price of an oem turbo.
In summary - F that.
Who invented the check engine light ? Where does he live ?
A remanufactured turbocharger might be a bit cheaper, I know in my part of Australia we have a specialist who rebuilds turbochargers !
That turbo is only $1100, new, at Rockauto.
Does that include installation and a warranty?
I think it's absolutely criminal that just having the light on can fail emissions. A turbo spooling a bit slow isn't creating any pollution. Something like a flaky alternator field circuit isn't creating any pollution.
Everyone loves a turbocharged vehicle until it fails. Then the green tears begin.
Ivan these are great cars....however if its got over 100k you need to replace the actuator assembly or at least the eye bolt that you adjusted...the eye bolt is available on ebay less than 50bucks...the round eye becomes wore out throwing of the clearances and changing the clearances while in operation....
didnt catch the seized rod till later....unforunate.
replace the car
Hey Ivan.........when are you going to get your new "Horse Stable" with the 4-post lift..............😁😀
Awesome diagnostics there Ivan why do we have to be so darn technical but if you can afford an Acura you can afford some serious parts replacements good job there boy
"If you can afford an Acura". The car is 18 years old. He may have bought it just as a fun car to drive.
i cleaned turbo vanes one year ago, they are stuck again
Thanks Ivan!
Spray the turbocharged with KROL inside and out let it soak?
Dropping the front subframe and installing a quality after market turbo is a lot cheaper.
How unfortunate, Ivan! To hit a roadblock, after all that effort, particularly when it could potentially be solved with no parts required! If only there was access to the turbo... So annoying!
Just curious, have you ever been pulled over testing a customers vehicle or looking at scan tool data? With my luck - I wouldn't be able to do that lol
Max boost is supposed to be just under 14 psi (1 bar), to the best of my recollection
you can't even get a long steel rod onto the lever? how about applying some higher pressure air to the actuator? It's made to withstand 30psi, it should be fine with at least 60psi. even if it blows something, it's already broken, so no harm done? plug off that port on the charge pipe so it's not losing boost via the blown diaphragm, and send it on.
Isn't that insane? Wow!! He should find a Lick-em and stick-em inspection station that "doesn't do those kind of inspections" Good job Ivan!
$7K for a turbocharger? WTF? There's an opportunity for some aftermarket company!
wow
Waste gate sticking?
Replace the whole engine , I don’t know why states up north people get so messed up with cars , down here in the south there is always a way to fix cars !
What repair do you suggest doing?
6.0 l ford diesels have a bad case of vgt vane sticking needs to be split and de carboned
Ridiculous cost for that turbo. The cost of older higher tech vehicles.
Your videos are always so informative and interesting! Thank you for that! 🧡💖
Your videos are always so inspiring! I look forward to seeing more episodes! 🌺💚
See my comment from part one. Cheers Ivan.
Is there a state one could drive it in that does not require inspection?
Michigan, for one.
It varies in Pa. from county to county, as rediculous as that is. My county has no emissions tests, except for visual, and a neighboring county has emissions testing for inspection. Go figure. Pretty much normal for anything the government has their money grubbing fingers in. And many states have no yearly inspections. Go figure again! 😅😅

Look at all the only fans hooks posting on your channel. LOL
Get a FL plate $35 yr, no inspection.
ask yourself why they sell mostly in the us
Darn pixies
Better a clapet loose than too tight. $$$ Don't floor it and this Acura will last the remaining
7k for a new turbo?!?! You can get a whole new engine in an old Chevy for less than that. Ask me how I know 😂😢 Hellish diag to take all that time, effort, and frustration just to discover the worst. Ugh.
I'd buy one off rock auto before I pay that kind of money for it,
I'm surprised the flow chart didn't say and then stand on one leg and rub your belly clock wise 😂
All that stuff to improve emissions, I would guess. No thank you.
Lol... the Ukraine bots got Ivan... 😂😂...
Also drop the Tr.!ump flag and it will stop... delt with this 8yrs ago...😢
Do yourselves a favor, don't buy ANY car with a Turbo.
It's getting hard to find cars without turbo

Hmm now BMW’s are looking awfully reliable compared to this Asian beauty.
Keep believing that!
Wow, simple stuff is bttr, i think a 1 motor tesla s., veh is simple enuff. And an old trusty ecotech no turbo backup 😂
This one genuinely makes me angry. Like, no kidding angry. It's a perfectly running and driving vehicle reduced to trash entirely. If he lived in a zero inspection state he'd be fine. Rrrrrgh this makes me so angry.
The juice ain't worth the squeeze.😕

mister OverEngineering strikes again...LOL....what happened to just a plain turbo and waste gate....SMH
Buy a small block Chevy from the old days. This is just plain stupid.
First, no spam ;)
Export to Africa. They will get many more years out of it.
This is why I'm not a fan of turbos.
It depends on the application. My 1983 Mercedes 300D-T had the original engine, turbo, transmission, and differential when I sold it at 450k on the odometer and the guy who bought it from me kept running it until it rusted down to nothing. Back in the day, simple turbocharged diesels were bulletproof. Late model turbo gas cars are a completely different story, and ever-increasing intervals for oil changes don't help.
Had over 300k on my Eclipse 2.0 with no engine or turbo problems. Trans started slipping when cold. Traded it in and got my retirement present.
Send turbo to area diesel service in illinois and have it rebuilt
Love the trump sign over your shoulder. MAGA 100%
