Help with 80mm TB codes?
I have had codes with this 80mm TB addition for a long time. At least I assume that is where it is coming from. I can clear the code but ot always comes back. At times, only after 20 miles and sometimes after 150 miles.
P0505 Idle control sytem (confirmed)
P0106 Absolute pressure system (Possible code)
My 80mm TB part number is 113 140 0104
I switched the 1-4 and 5-6 wires. Is this right? Car has always run well but will get a rough idle from time to time and one or two codes.
I have heard the 2-3 wire may be the correct switch or is my manifold sensor out. Maybe even a bad pin connector from the TB to the main line?
I thought my TB was from the 07 SL55 but not sure now?
\
Any help would be appreciated. Need an inspection sticker

i'm speaking from direct experience here and i know a leak before the tb seems highly unlikely to cause this but your airbox (y-pipe) not mating properly to the tb will give you the generic p0106 code and cause an intermittant rough idle. find a way to seal the y-pipe to the tb better and i'd bet your symptoms improve or go away altogether.
haven't had any issues with the p0505 code so someone else will have to help you there.

Thanks for the suggestions. Y pipe needs to be sealed better, for sure. I was thinking leak after the TB but this issues was on both motors now. This motor has a new inlet and gaskets but same y pipe, as other motor. The Pressure sensor is also the same from other motor. Other than that, nothing is the same but the codes.
Same TB
Same y pipe
Same absolute pressure sensor
Just tried an inspection and cat sensors are not locked in yet from my re-clear. They say drive another 30 miles but that may be hard without a code hitting..
Is there a 2-3 wire pin switch? My wire switch ok? Anyone have trouble with Pin connections?
Dealer said they warranty those TB pin connections all the time. they claim you touch them and they go bad.. Not sure about that..
Damn, I got work to do to catch Bassn 07!!
546 RWHP , 11.28 and no internal mods is sweeeet! No time to jack with codes.. help

Cross fingers and back to inspection in the AM..

You could possibly have a vaccum leak between TB and kompressor.
To confirm, you will need to plug in OBDII scanner and look at % of TB opening. If it is below 3%, than ECU is trying to compensate for the leak by closing TB and than runs out of adjustment.
Good Luck!

To add to this. I had a leak between the throttle body housing and the kompressor. I cant remember what the code was though. To find the problem I sprayed brake parts cleaner on the suspected area and sure enough the car stalled out pin pointing the problem area. A bit of high temp silicone solved the problem for me.

I will try that, as my code came back this morning. Even after I made all the fit checks. Just the idle control code.

Hooked up the scan unit and Throttle position is at .8% at idle and 1.2% in gear.
Idle is 660 rpm range in park and 580 range in gear.
I flattened my throttle blade mount a while back. If I marked the inside of the TB with the die grinder , could a small nick be enough to cause a code (air leak)?

Take TB off and check the area where it has been ground.
Those numbers sound very low.
Can you install your original 74mm???

i used an OEM rubber part between the TB and Y-pipe to stop air leak there which was causing the car to make hickups when the speed @ 35 km if i remove my foot from the peddal
part # 119 141 01 67

I just noticed this thread and I have or had the same thing with the idle control CEL. The only thing I found was a loose vacuum hose connector that goes into my airbox. I'm hoping this was the problem but it seems that some are saying it's after the TB...crap. I received this CEL twice since my new TB install and if it happens again I'll need to contact Renntech and see what they suggest. I'm hoping it wasn't a install error because it was done several hundreds miles from me. Just a side note, my car has run very strong with this code and I believe it's not affecting its performance, at least I hope. I've gone 600 miles without CEL...keeping my fingers crossed.
Please let me know what you find out and I'll do the same.

...have had the same 2 codes for 3 months now, with same symptoms...... obviously more common than I thought..... still haven't figured the problem...... also had throttle body knife edged...... at idle, my throttle position is at 1%...... am thinking vacuum leak also. Will get it looked at next week and keep you updated. Am running the 1-4, 2-3 swap now as I have found that the symptoms are a lot less severe, but my throttle body is from a 2004 CL600 PT# 275 141 0625.

That is bad news! Who else you know that has thew code? Maybe it is CL class realted? I can only get 50 miles after a reset, until it comes back.. Been trying to get and inspection but code comes back just as I try and take it in..
I am still using the 1-4 and 5-6 switch.. Can you go over 50 miles, until the code comes back? It seems the larger 80mmTB would let more air in at idle anyway, unless the PC was calibrated for the alrge TB.. I would think more people would have this problem, now that I think about it..

Am starting to think it is CL related too, although there seems to be a few e55 members with the same problem. Actually seems somewhat common. 50 miles, give or take, is about as long as it takes for my CEL to come on also. I do have Powerchip that was tuned for the 80mm throttle body and that did not stop the code from coming on..... Don't know of any other CL55 members with the 80mm besides you, but it would be interesting to find out. I did post in the CL55 section some time ago regarding the codes, but no answers.
I am sure you have run 11.28 , so that is what I meant.. Was trying to help you out bro.. I was giving you a little pad on the time, so when someone says they they beat your 11.28 time,, you can whip out the 11.2360000.

If the idle code is TB related, then it seems the 82mm Calibration could also not be calibrated for our engines air idle needs. then it again, it may have a dead on calibration. If a 74, 80 and 82mm were calibrated to be open at 3%, then the larger TB`s would let the most air into the motor at idle. Flap would try and close to compensate and go past the parameters the ECM would allow. then Bam! New code. 50 miles, seems to be right were all the emissions sensors try and lock in.. Always about a block before I can get to the inspection place..lol

hey guys, I have the same code P0106 and the exact same symptoms. I also have another problem... My cruise control doesn't work! My mechanic said it was because the TB needed adaptation until then the ECU blocks the cruise control. is this true?
