- Trailblazer Clean Throttle Body ,Electronic Throttle Control, P0506 P2119 P0106 P2176.Electronic Throttle Control .On this Chevy Trailblazer I read the codes and cleared them with a Snap on Solus Ultra. A few days later the Chevy Trailblazer was dropped off to get fixed.When the Chevy Trailblazer came back the Solus Ultra showed it had a P0506 and a P2119 code. Both codes and the codes of the first reading can be due to a carboned up drive by wire Throttle Body.I mainly used Throttle Body Cleaner ,but also used a soft rag and soft bristled brush to clean the drive by wire Throttle Body or Electronic Throttle Control..I do not like to open and close the drive by wire throttle bodys by hand and only open just enough to clean.I guess after removing the drive by wire throttle body ,you could hook the wire up and with engine off keyon ,have some one step on gas to open it.This is how I clean Electronic Throttle Controls ,others may use different ways.

Awesome video! My RPM's were fluctuating wildly when the AC was turned on. Cleaned the throttle body per your instructions and problem solved. I was really surprised how gunky the backside of the flapper valve was. Now my '05 trailblazer is running like a champ again. Thanks!
+Robert Gillin Thanks for watching and commenting
Thank you! I just watched a million videos trying to figure out how that electrical connector comes off without breaking it.
Glad it helped
@@wtbm123 Thank you! Got it all back together and it runs like a new car!
I have been watching several videos on cleaning the throttle body, just wanted to say, your video graphics rank as one of the best. Good work and explanations. Thanks!
Wow, thanks!
As it was said before I too am always learning from your videos Terry. Please keep doing them.
Thanks a lot man! Ten bucks and thirty minutes later she is running perfect!
Thanks for watching and commenting
Just did this today and my Trailblazer runs like a champ now!
wtbm123, U took that apart and put it back together again without a single profanity, I am impressed! U made it look easy and it even worked, good video!
Oh I just edit out the profanity. lol
wtbm123, One has to respect an honest man! U did make the whole thing look easy. Thanks for the video.
Nicely done. I'm sure it will save someone out there a ton of headache.
I hope so.,I have seen people get charged $150 to $200 to have it done.
Me I have a mygrain lol I kelpt telling the machanic it was the throttle body
Thanks this fixed my problem ,RPMs would drop when AC was turned on and eventually kill the motor and AC turn off and on like AC was bad. Cleaned throttle body per this video and all is FIXED..!!! Do this before you take to shop and get taken for a ride . Thnaks for the video !!
Thanks for stopping in and letting us know. Glad you got it fixed
Followed your procedure and it worked perfectly. Thanks for posting this!
+Ghostchanter Thank you for watching and commenting
I just did this to my '06 Trailblazer. Had the engine light for Idle Air Control low, not to mention low idle speed affecting the A/C temperature at idle. After cleaning up the throttle body, the truck is running perfect and the engine light went out on its on rather quickly. Thanks for the spot on video guide!
David Mallette Thank you for watching and commenting
No problem! Now if I could only find a video for replacing the parking brake shoes I would be all set.....lol
David Mallette Closes video i have
ua-cam.com/video/bSS1qHMNdLM/v-deo.html
I think that helps me out. I know the parking brakes are similar on mist GM disc brake setups. Thanks for the help!
Thank you so much!. I have a 2006 and with your advice, I finished in an hour. Trailblazer runs great. Check engine light is off after leaving it running for about 10 minutes. Keep up the good work.
Glad you got it running good ,and thanks for watching
Another great video, you make it look easy Terry
On occasion, I get the same symptoms. Idle starts to get rough and then nearly stalls and then goes into a low power/limp mode. My throttle body is clean. Other than that, my trailblazer runs well. 340K Miles.
Thanks, I just fixed mine thanks to your video! It worked.
Thank you for watching and commenting.
Perfect video Terry, covered all the if and whens plus your style of cleaning, very nice production brother !
Thanks Doug , Haven't seen any vids from ya lately hope I not missing them.
Looks like this solved my problem with my 2006 Trailblazer. Thanks for the video!
Awesome video/instruction by the way. I dont know if it was just coincidence, but after an alternator failure and installing the new alternator, the very next day the 03 trailblazer started idling rough, revving up, slowing to almost stalling(stalled a few times actually). only codes I was able to get were BARO/MAP, VAF, and a reference to throttle body intake tube loose.
Thank you for detailing how to remove wiring harness!
Glad it was helpful!
Just bought and 05 and behold it has this problem. So I will give it a go tomorrow.
It works, plus changing one coil for a misfire. See on you tube how to switch the coil from the misfire to another to make sure it is the coil. Replace all spark plugs and it purrs like kitten now. Wouldn't mind finding and SS now. In love with these trailblazer. lol. Thanks for sharing God bless
He almost left enough gas for a test drive... I'd be hopping mad if I ran out of gas on a ride... Great information Sir. Take care, be safe!
the gauge is broken. .thanks for watching
My GMC envoy had same engine code and rough idle while in drive and park even worse idle with A/C on. I took everything off used proper cleaner and put it back together.
I will tell you it worked like a charm idles perfect A/C on or off. Thank you for the video it defiantly helped. And yes with just a little of carbon build up it can make a difference in the engine. Took me less than an hour and i really appreciate the video.
Thanks for watching and commenting
Best T.B. video I have seen.
Thank You
Great lesson on a common issue. Thank you.
Thanks John
Any time your removing electrical plugs/components on a vehicle you should always disconnect the negative battery terminal an the line your referring to as a fuel line is not a fuel line it's a vacuum line I'm sure those that have any kind of mechanical sense know this but seeing as this is You Tube an most are watching this to learn I just figured I'd point that out. Other then that I found this to be great video showing how to clean your throttle body on envoy's/trailblazer's with the 4.2 inline 6. An really is the same on any drive by wire vehicle
Sorry I said it wrong. , and you can un hook battery if u want but with key off those have no power. Plz make a video showing how you do it. Thanks for watching and commenting.
Awesome video bro! Thank you helped a lot on my 09 Chevy Trailblazer LTZ
Glad it helped!
I have a some model same year TB, haven't had any issues yet. Good information though. Thanks!
Thank you for watching and commenting
Excellent video.
Always learning watchin' your videos.
Thank You
Another nice one Terry!
Thanks EZ
Great how to ! Very informational
Thank you
Very informative, thank you much buddy. 😎
Thanks for watching and commenting
Nice Terry, going to have to do that on my Grand Prix soon.
They are not bad to do if it is not -30 degrees out. lol.
Great vid this is going help out alot of people for sure Terry! CJ
Thanks CJ.
Thanks. Quite an informative video my friend
Thank you
Snug is the same torque in metric and imperial...good vid Terry..
Yea ,you know how it is,after a while you just get a feel on how snug is good.
hey pardner, my thanks. Till I saw this I didn't have a clue.
Thanks for watching and commenting
Thanks for the video!!! Very well done.
Thank you
Worked like a champ!!!
Thanks for the Video worked great on my 2002.

Nissan Titan throttle body sensor
How to replace a Nissan Titan throttle sensor
Sir, I went with your guidelines and the Pb on my Envoy 2006 was fixed! The engine check went out after 20 min.
Thanks for watching and commenting
I have a 2006 trailblazer and have these issues as well. There was a recall about the senor in gas tank and they would do repairs but because i had gone over mileage allowance they fixed mine but i had to pay a reduced price. Mine went bad right after i bought it. But i still have idle sensor that is supposed to be bad and mine has cut off is the air is runnung.Bought new in 2006.
Good Job Terry :)
Thank you
very nice instructions learned alot thanks
Thanks
I missed this video. COOL
thanks
Great little vid, thanks.
What's that black thing with plastic cover called ur screwing the carbortator to I'm trying to take of head gasket and I need that off
I'll give u my number if it's easier
good fix dr. terry
Thank You
Sounds like a job for "SEAFOAM spray super clean". Faster than a speeding engine and able to leap tall throttle body's in a single bound.
very good info in this thanks for sharing
Thank you for watching and commenting
Very detailed nice video. This is what i need to do. Only thing I'm wondering if you should replace the throttle body gasket.
If flattened or looks bad yes , if able to get one at the time of repair yes
Used to keep old toothbrushes for such sensitive things
Yes they work well
great vid terry
Thanks Jay
Good vid Terry
Thank You
Thank you. Great vid..
My TB was so encrusted with carbon, cleaner did not remove anything. I had to gently scrape it, spray it and scrape some more.
I also disconnected the battery when removing the TB and the computer relearned idle after running rough for about 30 seconds.
Glad you got it going again , just be careful not to scratch the coating off the inside ,
FIRST!
Another great tutorial. thanks
Glad you rushed over to see my video.
What kind of OBD software would you recomment to perform idle re-learn?
Thank You. The plug had me confused in a garage with shadows! BTW mine had 133,000 on it and was much much more dirty than the one you showed. Pulled the 2 fuses when done and waited 1/2hour. Replaced fuses and idled for 15 mins then took a short drive. Idle ended up looking like about 740 on the gauge but the Trailblazer is running fine. Oh and to finish off replaced the gas pressure sensor right next to just because it's old. Now I have new O2s (front and rear bank), new air filter, cleaned throttle body, cleaned airflow temp sensor. Anything else in that pollution path I should be replacing "just because"?
Sounds like it should be in good shape now .
@@wtbm123 It's fine
I have a 07 TB L 6 motor that stalls on cold start up I'm gonna clean the throttle body and I don't have to pull any fuses or disconnect the battery right? As long as I don't lift up the throttle plate? Thumbs up subbed
Thanks for the video. My 03 4.2 just started showing P0510 code which is "closed throttle positioning switch" I think I have to remove the throttle body and clean it thoroughly and see if it does the trick
If dirty , cleaning may help , but with that code , you may have a throttle position sensor or closed throttle position switch needing a new throttle body assembly . Sometimes wiring by the throttle body has issues . Maybe a clean and a throttle body relearn would be worth the try .
@@wtbm123 I did just that and to luckily the code went away. I thoroughly cleaned the throttle body and reset the PCM after.
@@Iliya_sh72 Glad you are running ok again , Thank you for sharing your code and comment , it may help others some day
thanks, very good!
thanks for the video i have a used 02 TB about to hit 250k miles only had to replace leaking AC but will need to do this in future the dealership will overcharge u lol
Thanks for watching
Great vídeo!!!
If you unplug the throttle body connector, Will I need reprogram it using scan tool?
Thanks a lot
j charles Not for just unplugging it
That was a great video Terry. Please share the name of the fluid you used to clean.
Throttle body cleaner . Most parts stores carry it . Thanks for watching and commenting
thanks good tips
Do you have to disconnect the battery to do this?
Good job thanks.
Thank you for watching and commenting
Great video. Is that a crack on your display screen?
a tear in the screen cover
Thank you!
My TB needed a new battery, after installing the new one my check engine light came on. I clean the throttle body and MAF sensor and the light never came back on. So yes it does need cleaning or replacing at times.
6:26 How did you get the fuel line off without fuel spraying all over the place. I went to change the Fuel Pressure Regulator off my 1998 Pontiac Grand Prix GT on the 3800 Series II engine and that thing popped up out of my hand and sprayed fuel all over me. Changing it fixed the first start stalls I was having but damn that was a lot of pressure there.
i did not remove fuel line with liquid fuel in it . but if you do for something like a pressure regulator , then you can pull the fuel pump relay and start car and let it run till it quits this will remove the pressure with no mess
wtbm123 Yesss!!! I can't believe I didn't think of that! Well, it's done now, I'll know for future reference :)
My 2005 trailblazer when I go up hill revs up and down and some times does it when I'm driving 60 mph could it be the throttle?
good one..........tony
Thanks Tony
Thank you very much for this useful video, i have trail blazer 2007 LT and i have done the same what u done, its work perfect
Actually I found some oil inside the Throttle Body also inside resonator cover, any hint please
may be PCV Valve if equipped with one .
wtbm123 true , i will clean the area and repace the PVC Valve, thanks
Talat Deeb Hi , i think there is no PVC Valve on TrailBlazer 4WD L6-4.2L ,
i wonder how the oil came inside the resonator ? Any idea pls
My trailblazer had very low fuel ⛽️ it stalled on me once i got fuel in it it sputtering a little I’m thinking to clean the TB
hello what is the name of the wire connector to the left of the throttle body
Just wondering , couldn't it be that when the car is on idle the throttle still has a tiny gap to get air and that gap gets clogged with the carbon.Before i cleaned it i had to step on the gas a little which would open the plate when i stopped so the engine wouldn't die.
Most have an IAC valve that meters air for idle . After cleaning it may take a little time to relearn the proper idle .
What do you cal the black plastic cover you take off? Anyway, when I took it off I noticed a puddle of oil/brown liquid settled in the black cover. Not a lot but enough to notice. Why would there be oil in there and where could it come from?
misterdinkly I guess you talking about the air box plenum . If oil in there could be engine blow by , or crank case ventilation issue.
wtbm123 Ok I think the oil that collected there took hopefully 11 years to accumulate.
+misterdinkly CHANGE THE PCV VALVE [ POSITIVE CRANK VENTILATION]it might bee clug dup
the hose from the crankcase cover leads into it. Your truck is smoking too much apparently. Bad valves apparently. 1 or all.
I have a code 2176 2004 Envoy change the throttle body unit , nothing when turn key on gages flicker all dash lights come on then go out no start.
I did what you said step by step and it's idling weird going from about 2 thousand rpm to nothing what did I do wrong?
If it is not throwing a code then after running some it may relearn on its own . If not then it may need a relearn .
I will have to disagree with Ed below. There is a need to clean the throttle body as you can clearly see the carbon buildup in this video. The car was throwing a code for throttle body cleaning and it was running rough. This guy should have disconnected the negative terminal on the battery or you can pull fuse #10 and #28 and wait about 10 minutes. This resets the PCM computer so it will learn the now clean throttle body..air/fuel mixture
uploadthis2011 can I pull the fuses before I start unplugging wires? and should I disconnect the negative before I start just to be safe?
misterdinkly You can
wtbm123 Awesome..thanks for the info and video!
do you have to take it off?can you just spray it??
Changed battery and same thing happened. I'm going to do this tomorrow. Did you disconnect the battery prior to this? Some say yes and some say no. I would think you would so it would relearn idle with a clean throttle body
Un hooking battery will reset everything to start new . If ket is off there should be no power there , but unhooking will not hurt
Alright I got a Blazer 06 after I got my rotors done it now sounds as if I'm shaking a tool box like it might break in pieces and when I change gears too. I Asked the Mechanic why does it do that he said : " Is normal happends over time" :| Not satisfied with the answer. Just curious if anyone has an idea what could it be ??
Try a different garage
I found your video because I'm having issues with the battery meter recently dropping/bouncing pretty low. I've seen that cleaning the TB could potentially fix that, and I see from between the 00:14 and 13:40, it's increased. Was that a result of the TB cleaning? I've not noticed any idling issues, or rather any change in idling.
What kind of obdII code reader do you have? does it connect through your laptop? Where did you buy it? I LIKE IT A LOT!!
I have 2005 Trailblazer LT with the 4.2L and was told that the throttle body couldn't be cleaned and should just be replaced due to the type of housing used on the part. Something about it would "melt" it?
If you use the proper cleaner and do not scratch it all up it should be fine . I think i mentioned in the video about some having a coating, but maybe not . The one in the video is still driving daily .
After cleaning throttle body my trail blazer 2007 LT's RPM is not coming on idle and A/C stuck on defrost.... any suggestion or idea to fix this.
RPM gauge is displaying between .5 to .6. and engine has little vibration as well and not as smooth as before.
Shall I connect the computer and check the code.
Thanks in advance for the helping comments.
if it was smooth before are u sure everything is hooked back up. sometimes if you open drive by wire throttle plates it can cause it to need to relearn idle. Not sure on the defrost that should be a separate system. sometimes if idle relearn does not do it its self you may need a scanner to put it in relearn.
Cool
Thanks
Yes amsoil power form?
You can use it , but i prefer not to wash all the crud into the engine . then it goes into the catalytic converter
لماذا يكون مؤشر البطارية مرتفع عند بدئ التشغيل فوق 14 في البليزر
thanks great video question; can this apply in a 2006 model ?
should be basically the same
Also Ed, "Silencer Box?" I think u mean the resonator cover.. You show your ignorance here.
My good man, you had absolutely nothing to add to this conversation, and if I may be so bold, your pretentious wording shows your douchiness.
Hello I switched over to a new throttle body because my code said it was bad. I sinked it in and it started I drove around for a couple blocks pulled in the drive way turned the car off went to turn it back on and it would not start it would crank over but no fire. Any suggestions on what else it could be.
Maybe check wire connections . Hard to say , with out looking at it or plugging in a scanner to see if it is communicating with the vehicle . I would check for fuel pressure and spark .Wonders if it has a crank and cam signal . Never know it may or may not be related to the throttle body . When you figure out the issue , please let us know as it may help another .
Im gonna do this in the morning. my Tb is shaking and the idle flex's and sometimes it gets so low it kills the car.
+jehova lopez Hope it helps , not sure what u mean by TB shaking , may also check for a misfire as those coils do go bad from time to time
+wtbm123 trailblazer is TB, lol sorry. coils are fine. replaced all 6 and plugs 20k miles ago.
any reason why you should not open the throttle plate in order to clean better around the area where the plate touches the wall where it seals?
Sometimes it will mess with the calibration , and a relearn could be needed . some can relearn on their own but some may need a computer to do relearn . could idle at a very very high rpm .even 3000 is possible .Plugged in key on, gas pedal to floor , most will open
I was looking at your two gauges oil pressure and battery is it normal that they move higher than 40 on oil pressure and up to 16 on battery when you speed?? I don't know if that's a issue but I'm concerned about it I have a 2002 bravada that is doing the same
I saw a similar video on this and what the other guy did was after he re-installed the throttle back into place, he went over to the fuse box and disconnected two of those fuses and waited 15 minutes then put them on, is that necessary or just do it your way?
I used a scan tool to remove codes. If the car is fixed by the cleaning the light will go off in a few miles anyway. Thanks for watching and commenting
I found oil in the resonator when I removed it. What would cause that? Thanks.
Maybe blow by . if a lot of oil i would look into it , but also sometimes with the carbon build up it looks like a coating of oil .
I read that disconnecting the negative terminal and waiting to reset the PCM can cause problems when the battery is hooked back up. Some say the HVAC system actuators can break. Is there any truth to this?
misterdinkly Every time power is cut , and re energized , it will go through a relearn . It opens and closes the HVAC doors . If the relearn does not complete then HVAC will not work properly . Most of the times you can disonnect the power again and wait a min or so . then re power . turn key on and do not touch HVAC controls till relearn is complete . I believe in most cases if one actuator does not relearn then there was starting to be a issue with that actuator , or door anyhow , and would of acted up in the future anyhow .
wtbm123 very good. Thanks. Would disconnecting for half hour be any different than disconnecting for just a minute? It relearns no matter the time off the battery?
