Topic: P0106 on 07 Opel GT

[Arabas]

a friend of mine, has a 07 GT and is getting a P0106 every time he pushes it hard.
we suspect this must be a hardware part.
any ideas on what he should check?

P0106 Manifold Absolute Pressure Sensor Performance

I would point the MAP sensor from intake manifold. I had this in the winter when the engine was cold and I was trying to push it. I have this from time to time when I race and I make big boost like 1.8 bars. Can't he borrow a MAP sensor from a different GT and test it?

[Arabas]

we already ordered an new map to test this (since the cost was reasonable), but it will take a while to have it here.
hope this is just a case of failed map sensor..
forgot to mention that he has no other symptoms, BUT he is lacking power compared to me when this shouldn't happen IMHO

[Kelu]

Also don't forget to check the harness.

[Gentleman Jack]

have heard this can also be attributed to recently oiled air filters causing disruption in MAF sensor, throwing off readings and causing other sensors to code.

don't know if this applies to that particular GT, but something to check.

[Yogi]

Did the new MAP sensor fix it?  Which one?  The one on the cold charge pipe or the one on the intake manifold?   

[Arabas]

Yogi, we just received the parts (i m going to pick them up actually) and we will be testing that soon.
for the record, car works fine, he just gets this code once in a while, so he has learned to live with it.

do you have a tune? if yes, are you pushing it to max power?

[Kelu]

I have that code from time to time, like once at 2-4 months, sometimes when I race, sometimes when I do long trips, I delete the code and continue driving.

No, I do not have a tune - just a stock LNF.  I push it really hard once each month when I AutoX, but daily driving, not so much.  Never had a code - yet - but I guess that's not surprising.   

Thanks for the feedback and let us know if the new parts solve the problem!

Hey Kelu,
How do you delete the codes while driving?  You must have a really cool code scanner...

[Arabas]

Yogi, since you don t have a tune, you should be looking for a malfunctioning map sensor... i hope nothing more than that...
i just got the map sensor and we will try it. will let you know

Arabas - I guess that I mislead you by asking about this problem.  I do not have this problem, I was just curious if the new sensor resolved the issue, and which sensor worked.   

I'm sorry for any inconvenience.   

Yogi

[Arabas]

OK Yogi, got it now...
i thought u had the same code.

[Kelu]

Hey Kelu,

I have THE best scanner around here, I use it on different cars and works flawlessly and the information about codes are awesome. Now I have to watch it carefully so it won't disappear.

THANK YOU FOR THE SCANNER GJ

tonight, we have a scheduled mini meeting (4-5 GTs).
we will pretend to be mechanics and see what's wrong with the 07 GT and the P0106 code, some knock onow and then and not as much power as the other GTs are making.

what we are going to try is:
race of 07 GT and another 08 GT which runs great- check difference

then, replace the old map with new map sensor we received
race of the same cars and butt dyno , scan for codes after that

if the result is not as expected, i will put my maf on 07 GT
race again, butt dyno, scan for codes

so, we will be using one car as a performance standard and check.

we will inspect all hoses and everything else we can.
the only problem is how to check the IC fro cracks, without removing the bumber....

any other ideas that might help?

will post late tonight or tommorow the results.

[Kelu]

Arabas: to check IC cracks use Kenny's Boost Leak tutorial.

Guys get around and let's wait the news, the greek news where we gonna see 4-5 Opel GT owners getting tickets 

[Sol Asylum]

Kelu did you call the Greek police and invite them to the big race?

Arabas where are you all meeting for you little race, some of us might like to stop in and see whats going on?

[Arabas]

Update for anyone interested.

first of all, Kelu and SA, one of the Greek GT guys we hang out together is a police officer...so we have our a$$es covered. you see, Greeks try to be smart  

only 3 GT and one Mazda 3 MPS.

meet my friend with the 07 GT that throws the P0106. i told him to go racing to see what the difference would be and to see if the code would appear, generally how the car felt on the road.
he said he wasn t going anywhere, because he had knock on 2nd, 3rd and 4th gears...

popped the hood and took maf out and cleaned it.
checked the pcv hose, was clean.
when we went to the map, i realised i had ordered the one on the manifold and not the one on the IC pipe... changed the manifold one though. it had oil on it, so i wanted to check the ic pipe map too. oil there too...

after these indications it was time to take off the intake pipe that goes to the turbo.
oil in the intake pipe...quite a lot i must say, cleaned the intake pipe, cleaned the small metal pipe in front of the turbo wheel and then i rotated the flashlight to the down side of the turbo...

and then i realised that he could have saved the map money...
Down side of the turbo, and the wastegate (i think that it is the wastegate) was covered in oil, down to the engine mount and down the dp...lots of it...

without being a mechanic, i suspect a broken down turbo
then we went to race it a little bit and see how it reacts. 2nd and 3rd gears were fine, 4th gear had knock...

i will post some crappy cell phone pivs we took tommorow morning.

i suggested he should go to a dealer and have the turbo inspected and replaced asap.
think he should take the ic and ic pipes out and have them cleaned under warranty as they should have oil...

at the end... P0106 popped once again, but that s of no importance imho

[Gentleman Jack]

wow, two turbos in a month.  Chuckdoc, did you send your Gremlin to Greece?

I would say no doubt on getting the turbo replaced.  I would ask that that IC and pipes be replaced as there is no efficient way to clean the IC.  Perhaps the pipes can be cleaned easy enough and they can be re-used.

let us know how it all goes!

[Arabas]

sorry about the low quality pics, none of us had a camera with him, and we were in the middle of the night in a deserted place with low lighting. cell phone with no flash was used.
on Saturday, my friend will try to take some daylight pics.

here you can see some oil in the intake pipe right before the filter

here is the wastegate covered in oil (top right corner of the foto)

finally this is how my finger is after just touching the wastegate

any ideas??

[Arabas]

my buddy just took some proper pictures of the turbo (wastegate).
you can easily see the oil on the wastegate and on the electric connector between the turbo and the wastegate, even further down.

i am looking forward to your thoughts and suggestions on what could the problem be.
he is taking it to the dealer some time soon, to check, but until then, we thought to see what you guys think.
Turbo, some seal, something else?

[Kelu]

Isn't that enough?

[LatinVenom]

I am guessing here but I believe the oil is coming from the area of the clamp.
It maybe that the rubber piece has a small crack or hole and it is blowing it under pressure.

[Arabas]

Just for the record and for future reference (i hope nobody will need this piece of information though).
turbo was loosing oil. the dealer honored the warranty but didn't replace it.
Took it to a turbo repair shop to be repared... the owner and myself were not happy about this, but it the dealer said that if anything happens it will be covered again.
also cleaned the oil form the pipes and from everything else it had spilled on.
seems to be working fine for the moment.

My friend is going to run hard the car these days to check if everything is OK

thanx to all of you who helped us with this issue
