Mazda 6 Turbocharger Underboost Fault Finding and Fix

[@jonbarnes5788]

Great video, I had the same issue and now fixed by using this video, my Mazda 6's performance is restored!! Thank you for this great video.

[@tomgifford7772]

Excellent video - thanks for taking the time and effort to make a good clear video.

[@nickkelly8795]

thanks for your video, i have the same problem on my mazda 5, your video has been a big help. thank you

[@sandyande]

Good video my friend I enjoyed learning about Mazda turbo control cheers sandy

[@FingerDinger187]

You are my hero! I had the same leak at the same spot! Thanks!!

[@crank3646]

Some heroes don't wear capes :D Thanks for watching :)

[@zoltansanta207]

Thank you very much! Solved my problem as well! Thank you guys!

[@markusjohansson7840]

Thank you for good video. I just fixed my car this way and now i have correct boost again!

[@catalinionutmate6480]

Thank you very much! I have the M6 GH 2.0 diesel version, and for a while already I have the p2227 barometric pressure circuit range/performance error. Thanks to your video I know how to measure the pressure compared with the desired one, I will try today, only thay I am using Forscan, but anyway it has a similar graph. I think my problem will be either a loss of vacuum either some problems with the intercooler.

I just saved a lot of money and time! Thanks for the great video! Благодаря за видеото! Беше от голяма помощ!

Great video, great job. I fixed problem with my turbocharger underboosting....Mazda 6 GY, 105kW, RF7J :) I´m used hose from blood pressure gauge and it´s working fine :) LOL

[@B.Ruslan1978]

I need to go to you and fix my Mazda6 2.2 turbodiesel 2014.I have the same problems. Sometimes turbo no power.

[@stephenjackson3129]

Great video. I've found i have cracked pipes going to and from the vacuum reservoir. What do I search for to get a replacement. Are they 4mm or 5mm diameter?

[@crank3646]

It should be 4mm

[@eduardjancius4974]

Danke deine video ist mir sehr hilfreich!

[@garysnell47]

Great video. I’m having a similar issue with a 2010 Mazda 6 MZR 2.2. Is the vacuum chamber the same as I can’t seem to find the same air box layout

[@cinematicshobbystudio8302]

Здравей, преди година беше същия маркуч ,сега вакума е слаб още от помпата. Обслужват ли се?

[@DinuEduard]

Man, please help me, i have a 121 hp mazda 6 same as this. New turbo, dpf off, egr off, new intercooler, ok vacuum lines and pump, the turbo vacuum electrovalve is ok, the car got verry little power, no stored codes, i have an autel mk909

[@danteseeker7]

8:22 One of the vacuum pumps doesn't work (the one that should have stronger vacuum). What could be the problem?

[@makertube6509]

That was a very good explanation. Thanks

[@MichalS-n6l]

Hi, you have very cool videos. I have a mazda 6 gh 103kw and when the engine warms up the power drops and the turbo doesn't work at all. I don't know what to do. I have cleaned the particulate filter, new turbo and new air weight. I'm getting desperate. Any idea what it could be? Thanks

[@toffifrimane7986]

You solves the problem ? I have the same issue

[@autocomplexrs]

Мерси видеото е добро.

[@cnackk]

Браво, момчета!!! Страхотен клип. При мен беше спукан на същото място маркуча. Ремонтирах го временно на един паркинг като прерязах скъсаното на маркуча. От къде мога да намеря такъв за да го сменя, че остатъка идва малко къс? Възможни ли са допълнителни усложнения по двигателя ако съм карал със спукан маркуч 10 000 км?

[@cristian-ionutmilencu6305]

You are the Best!!!

[@kristizh4443]

Same car here. I get p0401 and p0404. Don't have any issues driving but cannot find what the problem is. Any idea?

I have issue with my 08 rdx you may be able to figure out. driving me bonkers. I got it for a steal at the auction. Throwing p2263 code and p0420 and a underboost code p0299. Acura dealer had serviced the car it’s whole life. One owner. The lady had 176k miles and was already lookin at a new rdx. She brought it in because it was running slow on acceleration and not going past 1/4 of the way in boost gauge. The car runs and drives good but very slow and anything past 50% throttle and it feels like even more restriction. Lower throttle works ok just very slow. Sometimes randomly it will have a little more pep than others. I’ve checked for boost leaks. Replaced the maf. Reset the ecu. It did this worse with stock intake I Even got a aftermarket intake which actually helped keep the code from coming back as soon. But didn’t help power much. You can hear the turbo spool. In neutral it wil rev fast an no issue but no boost showing on gauge in park or neutral just builds in driving mode and builds and drops off when it shifts like normal but low. I’m seeing on my code scanner the cat temp gets up to 1300deg and when sitting it’s like 800ish. I see the 02 sensor voltage fluctuate a lot when i rev it. Not sure what it’s supposed to be. I wouldn’t think an 02 would make a dealer say bad turbo and cause this much issue but the master tech at Sutton told them it was the turbo itself. I just find it hard to think it’s the whole turbo. Feels more like stuck wastgate or clogged cat or something. I have never removed a turbo and I don’t want to mess anything up or throw money at it without knowing for sure what’s wrong. The actuator is like 230$. New cats are 275 I think. And a catless down pipe is 400. Refurbished turbo is 800$ on eBay. Used is 650. Any advise? I feel like if the turbo is bad it wouldn’t spool so quick to 1/4 boost and stop. It’s like an actuator or something flow control is stopping it. The rod ends look fine.

[@crank3646]

I'm not familiar with this Mazda . 90% of the time underboost problems are broken hose or actuator for the turbo geometry problem , with the control . Guess this engine doesn't have variable geometry turbo , it has waste gate to regulate the pressure , so yes you need to check it . If its controlled with vacuum , you need to see , does the actuator holding it , or not . Most likely is not the turbo itself .

[@cppctek]

Crank mine is an Acura RDX with a td04h turbo. It has a weird design. The turbo has a turbo flow control actuator and a wastegate actuator I think. The dealer says it’s a bad turbo but they said that to my buddy and he replaced his turbo flow control actuator and it was like new. Thanks for fast reply. I’m going to take it apart soon and check the wastegate and a the actuators.

[@cppctek]

I do have some data from driving with my code scanner I’ll upload and see if you can make any sense out of it.

[@MariusAgapi]

Hello, do you have any ideea where is located the pcv valve on Mazda 5, diesel engine, 2.0L,143 hp/2007? The engine is the same! Thank you!

[@zorankosevski]

Ty for the video great one i just fixed my car easy

[@AnnatarTheMaia]

Which OBD diagnostic tool are you using, and where can I buy it please?

[@andersw2274]

Hi great video! I have a strange sound to my mazda 6 2009 2.2d and its sounds only when im driving. Its like a ssssssss sound (snake or something) when am accelerating! Any idea? = )

[@nezaisk-73]

Do you know what is normal operation of boost valve. If you connect pressure gauge to valve output, what pressure it has to show when car is idle and what changes when you press accelerator?

[@TheMatrixcube]

Good video thx

[@plamenslavov7416]

Здравей, евала за видеата :) Имам проблем с мойта мазда 2.0 D 136 hp. Пропуши сериозно черен дим на ниски обороти след 2000 спира да пуши. Също так на свободна падат оборотите за момент с малко и после пак ги връща. И сякаш забави ускорението има забавяне от момента в който натисна газта до момента в който реално почва да вдига скоростта. Предположение?

[@crank3646]

Здравей и на теб ! Доста неща може да са . Без диагностика ще е доста трудно да се хване . Като цяло от дюза до липса на компресия може да е .

Hi ..very great mechanic..this is engineer level , technician level just only change parts.. what about citroen c4 picasso 1.6v thp . P0299 P2262 ..cannot accelerate more than 4 PSI.

[@Unitymoos1]

Здравей много се надявам да ми отговорите. Колата пушела ли е черен дим след 2200 оборота ? Имам мазда 6 136 кона дизел и незнам дали проблема ми е егр или нещо друго. След 2200 оборота колата не иска да ускорява и пуши черен дим което може би значи че не изгаря горивото. Има различни уроци които казват как да си провериш егр. Ивадих вакум маркучето което е към егрът и не усещам никъв вакум при форсиране. Бих бил много благодарен за мнение или помощ.

[@crank3646]

Едва ли е ЕГР . Бих заложил , сляпо , на спукан турбо маркуч .

[@cristij8436]

I looked twice but I didn't understand what the solution was. on the diagnosis, I get boost pressure below the requirements

[@juliosolis6532]

Buena explicación

[@viktoripad]

I didnt understand, you checked the pipes in the end but you didnt fix anything, why it started to work normal then?)

[@crank3646]

They were a crack in one of the vacuum lines , that was causing malfunction of the turbo control . Sorry if I didn't show the problem clearly

[@viktoripad]
