    thank you !!!!!!!!!!!!

    you don't explain why you need to clear the codes. Why do you clear the codes and how do you put back the codes?
    What happens if you don't clear the codes?

    Is both the sensors in the plastic cover or is there is there one in the throttle body its self. i took the computer and they are reading different but don't wanna replace just the plastic sensor if its the other sensor that isn't working in the throttle body. my throttle body makes some weird noises also is that common when the sensor is bad I did get the code for tp sensor 1-2 correlation p2135

    So I have the same truck.., I’ve been having a funny idle going on almost like slight back pressure ..no codes..just fixed a vacuum leak, Changed fuel pump, injectors, map sensor , maf sensor, air filter, entire evap system, coil packs , wires, and I’ve made sure it’s all GM certified yet I’m still having a very slight rough idle especially in park on the brake…. At times the idle drops close to zero at a stop feeling as if the engine is about to shut down then it picks back up ….. it always smooth on the highway

    Good walk-through Eric O I have done 100s of these never Had the system say Disagree its very rare to replace the Throttle Position Sensor and it Disagree and have to replace the entire Throttle Body @SouthMainAutoRepairLLC

    Hello Eric, I drive '05 Chevrolet C5500 8.1 Vortec, Which is attached to my 35' Motorhome. Anyway, I have this code P2135 and another one which didn't show up this time,
    Which was P0220, Raw code: 0220
    ECU: 10
    Status: Confirmed
    OBDII: Throttle position (TP) sensor B/accelerator pedal position (APP) sensor B – circuit malfunction
    So, first I just replaced the black part which you show taking off of the Carburetor.
    I had to drill out the rivets and install New one using the nuts and bolts provided, as well as I replaced the gas pedal with a GM Genuine Part.
    We went on a 2,300 mile trip up to Niagara Falls and back and just about every day the engine would go into limp mode and we'd have to pull off of the side of road and use my VeepOBDII Scanner and go in and clear the codes and then we were able to get back on the road usually within 15-20 minutes and then it would run great the rest of the day.
    When we were up in New Hampshire we had a mechanic who specifically was a specialist dealing with this issue. He checked everything out and stated it was most likely coming from the off brand TPS sensor that I replaced on the Throttle Body.
    So when we finally made it home I ordered a new
    WHOLE Throttle Body on it with a GM Genuine OME part.
    Well, today I had the engine running just to warn it up because it had sat for a few days and then I got that code again.
    Do I need to have this new equipment I put on "Flashed" by a GM Certified Mechanic?
    This RV going into limp mode all the time is getting old!! Especially if you're going up a steep inclined in a mountainous region OR even going down hill! Thanks in advance for any help!

    Hi My name is Glen. I followed your video on (Chevy / GMC Code P2135 TPS Problems). I am working on a 2008 Silverado with the same code. the only thing deafferents was I took the battery cable off to clear the code while I changed the sensor out. I installed the sensor with no problems. When I tested it out it was running about 700 to 800 RPMs but when I did the slow throttle up and down it stayed at 1500 to 1600. I let it worm up and test drove it but it stayed at the same RPMs. I took the battery cable off again thinking it might reset it again. It is now running 700 at start up but when you throttle it up it now runs at 2100 to 2200 RPMs. What would be my next corse of action would you suggests?

    All these GM trucks from 07-13 are garbage I’ve own 3 GM trucks and this generation is the only one that’s given me hell

  21. Avataaar/Circle Created with python_avatars Joel Highsmith says:

    Ever worked on a 2005-2006 Pontiac GTO with this code? I've replaced my throttle body and my accelerator pedal assembly, replaced maf sensor, pigtailed the connectors at the throttle body and maf sensor, tried a new ecm, pinned out the harness…. I'm about ready to park her in a lake lol

  22. Avataaar/Circle Created with python_avatars wendell worth says:

    You don't have to get it flashed. Just drive it and it will reset itself. Don't waste your money going to the dealer.

  23. Avataaar/Circle Created with python_avatars biofall38 says:

    They don’t make these for the 2014 year model or at the very least I can’t find one

    This has come on 3 times on my 2019 chevy Tahoe RST and $1000 each time it happens. When is a recall going to take place?

  25. Avataaar/Circle Created with python_avatars Kevin Milam says:

    I'm having the same issue with 2004 GMC Yukon 4.8 l. have replaced both throttle sensors and still getting the code

  26. Avataaar/Circle Created with python_avatars Melissa Pulka says:

    Thank you for this video! Just did my 2004 Yukon. Slightly different because I had to cut the rivets off (used a hacksaw on the top of the rivet).

    I have a 2012 equninox with a P2106 thats really stumping me. Found wires broken at the TB , replaced harness connector and TB assembly. All codes are now gone except P2106 and reduced power indicator and runs rough?

    I replaced my TPS on my 2010 Chevy 5.3 litre. Instantly ran the same. Any suggestions now? Traction lite is on as well as check engine still.

    I bought a new throttle body, but code p2135 is still there. is ecm the problem?

    So helpful, thank you!!!

  32. Avataaar/Circle Created with python_avatars Mike Cracco says:

    Did the truck ever come back with the same issue?

  33. Avataaar/Circle Created with python_avatars Brandon Smith says:

    I wish you were around me lol. My Silverado has this p1516 code. Replaced the tps cleaned everything on the grounds etc. It's a dangerous thing going 60 mph and bam lose everything.

  34. Avataaar/Circle Created with python_avatars Eduardo Rivera says:

    Forgot to check the gear teeth, needed to pull the white thing like u say inspect gear behind it connecting to motor if there are missing teeth or worn teeth then you did all that for nothing..

  35. Avataaar/Circle Created with python_avatars craig jones says:

    Great for the diy guy. But for the time spent cleaning it, would replacing it be easier ?

    I'm have 2006 gmc yukon xl slt 5.3L with P2108 P1516 U0107 codes . It just go in to reduce engine when I start it . Never even moved .

  38. Avataaar/Circle Created with python_avatars Lane Johnson says:

    Not sure if anyone would still respond to this post but my code reader is saying "Not Plausible" rather than "Correlation" What's the difference?

  39. Avataaar/Circle Created with python_avatars Bill Alderton says:

    I have a 2009 Envoy. The car was going into limp mode with a code P2135. (rough idle, stalling, ….. 2 times same day). Replaced the throttle body with a new Bosch unit for the 2009 Envoy. The old TB was fairly well carboned. I performed the relearn, it is idling at 700-800 after about 5 seconds after starting. However, when you start to press the accelerator, the car leaches because the engine jumps to 1200 RPM. You just have to barely move the pedal for this to occur. If you are moving and stop, wait 5 seconds, the idle will return to 700-800. If you are in park and you place the car in drive, sometimes the car will increase to 1200 rpm as noted above. I did not have this issue with the old Throttle body. I have driven the car 50 miles with speeds of 50 mph with many stops and go, I am not seeing any improvements. Any ideas? I can't find anything on the internet describing this issue I am experiencing when replacing the throttle body.

    I’m going to try this on my 09 H3.

    Very helpful. Very educational and pro job/video. Thanks. 356 thousand miles on my 07 Silverado. Only had to do this three times in mine so far. A GOOD OLD TRUCK. Still runs like new. I like the china garbage remark. Thanks again my american friend.

    The dreaded reduced power mode, it's common on the earlier models, usually the pins on the circuit board.

    Very good job 👍 👍👍 👍 very good teaching good teacher
    Nice video 👌 👌👌

  44. Avataaar/Circle Created with python_avatars Juan S says:

    In the past there was ABSOLUTELY NOTHING wrong with the simple cable running from the accelerator pedal to the throttle body. GM and probably others had to put all these PLASTIC GEARS, TPS In order to enrich these S.O.B.s
